Coding is seriously much faster now, and this is the slowest it will ever be.

Roon: pov: you are ten months from working for claude sonnet the new technical founder.

Garry Tan: Underrated trend.

It’s happening.

Sully: 50% of our code base was written entirely by LLMs expect this to be ~80% by next year With sonnet we’re shipping so fast, it feels like we tripled headcount overnight Not using Claude 3.5 to code? Expect to be crushed by teams who do (us).

Not only coding, either.

Jimmy (QTing Tan): It can also do hardware related things quite well too, and legal, and logistics (planning) and compliance even.

I’ve been able to put off hiring for months.

When I run out of sonnet usage I patch in gpt-4o, it’s obviously and notably worse which I why I rarely use it as a primary anymore.

Claude 3.5 Sonnet becomes the first AI to crush the Lem Test to ‘write an impossible poem.’

Laugh all you want, this is actually great.

Kache: dude hahahahahah i used so many tokens today on just formatting json logs

near: the just stop oil people are gonna come and spray paint you now

Compared to how much carbon a human coder would have used? Huge improvement.

IMO problems are still mostly too hard. The linked one, which GPT-4, GPT-4o and Claude 3.5 Sonnet failed on, seems unusually easy? Although a math Olympiad solver does, predictably given the contests we’ve seen.

[EDIT: I didn’t read this properly, but a reader points out this is the floor symbol, which means what I thought was an obvious proof doesn’t actually answer the question, although it happens to get the right answer. Reader says the answers provided would actually also get 0/7, order has been restored].

Figure out what song Aella was talking about here. Found the obvious wrong answer.

Grok offers to tell you ‘more about this account.’ I haven’t seen the button yet, probably it is still experimental.

Our price cheap. Llama 3.1-405B was a steal in terms of compute costs.

Seconds: “AI is expensive” its not even half the cost of a middling marvel movie.

Teortaxes: Pretty insane that the cost of producing llama-3-405B, this behemoth, is like 40% of *Ant-Man and the Wasp: Quantumaniamovie at most If I were Zuck, I’d have open sourced a $10B omnimodal AGI purely out of spite for the vast fortunes spent on normieslop as a matter of course

The real costs of course are higher. You need to gather the necessary equipment, clean the data, refine procedures, build a team, and so on. But once you’ve done that, the training run itself is still, it seems, in the low nine figure range, for 3.8 x 10^25 FLOPS, less than the 10^26 threshold in the executive order or SB 1047, so they got to ignore all that (and it doesn’t look like they were skirting the line either).

GPT-4o Mini Me, you completely lower the price. $0.15/$0.60 per million input/output tokens, wow.

Arena absolutely loves Mini, to the point where if it’s really this good then Mini potentially is an even bigger practical advance, in its own way than Claude 3.5 Sonnet or Llama 3.1 405B (which remains unranked so far, give it a few days as needed).

That’s Huge If True because this is a Haiku/Flash/8B level model in terms of pricing, that is claiming to effectively play in the same class as Sonnet and 4o even if its strict benchmarks aren’t quite there? Is this for real? And you can already fine tune it.

The consensus feedback I got on Twitter when I asked was ‘no one believes it’ and that this is mainly discrediting for Arena. Sad. I doubt it is ‘rigged’ given the details, but it suggests OpenAI is optimizing for Arena results or something that correlates highly with Arena results. Is that a good proxy for actual user preferences? Hmm.

Sam Altman: Towards intelligence too cheap to meter. 15 cents per million input tokens, 60 cents per million output tokens, MMLU of 82%, and fast. Most importantly, we think people will really, really like using the new model.

Way back in 2022, the best model in the world was text-davinci-003. it was much, much worse than this new model. it cost 100x more.

OpenAI: Today, GPT-4o mini supports text and vision in the API, with support for text, image, video and audio inputs and outputs coming in the future. The model has a context window of 128K tokens, supports up to 16K output tokens per request, and has knowledge up to October 2023. Thanks to the improved tokenizer shared with GPT-4o, handling non-English text is now even more cost effective.

Safety is built into our models from the beginning, and reinforced at every step of our development process. In pre-training, we filter out(opens in a new window) information that we do not want our models to learn from or output, such as hate speech, adult content, sites that primarily aggregate personal information, and spam. In post-training, we align the model’s behavior to our policies using techniques such as reinforcement learning with human feedback (RLHF) to improve the accuracy and reliability of the models’ responses.

…

GPT-4o mini is now available as a text and vision model in the Assistants API, Chat Completions API, and Batch API. Developers pay 15 cents per 1M input tokens and 60 cents per 1M output tokens (roughly the equivalent of 2500 pages in a standard book). We plan to roll out fine-tuning for GPT-4o mini in the coming days.

In ChatGPT, Free, Plus and Team users will be able to access GPT-4o mini starting today, in place of GPT-3.5. Enterprise users will also have access starting next week, in line with our mission to make the benefits of AI accessible to all.

That’s half the price of Claude Haiku.

Eli Dourado: Just occurred to me to run these numbers. GPT-4o is 87 tokens per second and $15 per million output tokens, so that works out to a wage of $4.70 per hour. GPT-4o mini: 183 tps @ $0.60 per MTok = $0.39/hour. A single instance outputting tokens all day would be under $10.

Needless to say, Pliny the Prompter quickly jailbroke it.

Greg Brockman: We built gpt-4o mini due to popular demand from developers. We ❤️ developers, and aim to provide them the best tools to convert machine intelligence into positive applications across every domain. Please keep the feedback coming.

On Sully’s internal benchmarks GPT-4o-Mini outperformed Haiku and (the older) Llama 3. With good prompting, he thinks it is ‘nearly a 4o replacement’ at 10x cheaper.

Sully notes that if you are transitioning from a bigger to a smaller model such as GPT-4o Mini and also Claude Haiku or Gemini Flash, you need to put more effort into your prompts, with clearly marked instructions (XML/markdown), few shot examples and edge case handling.

Swyx calls this ‘The <100B model Red Wedding,’ which to me completely misses the point of the Red Wedding but in context the intent is clear.

swyx: I do not think that people who criticize OpenAI have sufficiently absorbed the magnitude of disruption that has just happened because of 4o mini.

Llama 3 70b: 82 MMLU, $0.90/mtok

gpt 4o mini: 82 MMLU, $0.15/mtok

very model on the RHS side of this chart is now strictly dominated by their LHS counterparts

some of these models were SOTA 3 months ago.

what is the depreciation rate on the FLOPs it took to train them? gpt4 took $500m to train and it lasted ~a year.

intelligence too cheap to meter, but also too ephemeral to support >5 players doing R&D? is there an angle here i’m missing?

the other angle i have been thinking a lot about is the separation of reasoning from knowledge. RAG/memory plugs knowledge easily but not reasoning. 82 MMLU is plenty. you can get it up to 90, but it’s not going to be appreciably smarter in normal use without advancing other metrics. So in 2025 we’re likely to evolve towards 0) context utilization (RULER) 1) instruction following (IFEval) 2) function calling (Gorilla) 3) multistep reasoning (MUSR), 4) coding ability (SciCode), 5) vision understanding (VibeEval?) for all the stuff that RAG can’t do.

I disagree that the general version of 82 is plenty, but it is plenty for many purposes. And yes, it makes sense to find better ways to encode and access knowledge.

The actual point is that almost all past models are now strictly dominated, and this takes it a step beyond Claude Haiku on the low end. The objection would be that you cannot fully freely use GPT-4o Mini, and even when you fine tune it there will still be various rules, and perhaps you do not trust OpenAI in various ways or wish to give them your business. Perhaps you want a freer hand.

Even if we don’t get new better frontier models, it is clear we will continue for a while to get superior smaller models, that provide more intelligence faster at a cheaper price. No model that exists today, including GPT-4o Mini, is likely to be a good choice a year from now, certainly not within two, again even in the most fizzle-like scenarios.

The weirdest reaction is to get mad that this was not GPT-5.

Roon: People get mad at any model release that’s not immediately agi or a frontier capabilities improvement. Think for a second why was this made? How did this research artifact come to be? What is it on the path to?

It is fair to be perhaps disappointed. This is still large forward movement. No doubt the big model is coming in due time.

It is also, as I noted with Claude Sonnet 3.5, a pattern.

Andrej Karpathy: LLM model size competition is intensifying… backwards!

My bet is that we’ll see models that “think” very well and reliably that are very very small. There is most likely a setting even of GPT-2 parameters for which most people will consider GPT-2 “smart”. The reason current models are so large is because we’re still being very wasteful during training – we’re asking them to memorize the internet and, remarkably, they do and can e.g. recite SHA hashes of common numbers, or recall really esoteric facts. (Actually LLMs are really good at memorization, qualitatively a lot better than humans, sometimes needing just a single update to remember a lot of detail for a long time). But imagine if you were going to be tested, closed book, on reciting arbitrary passages of the internet given the first few words. This is the standard (pre)training objective for models today. The reason doing better is hard is because demonstrations of thinking are “entangled” with knowledge, in the training data.

Therefore, the models have to first get larger before they can get smaller, because we need their (automated) help to refactor and mold the training data into ideal, synthetic formats.

It’s a staircase of improvement – of one model helping to generate the training data for next, until we’re left with “perfect training set”. When you train GPT-2 on it, it will be a really strong / smart model by today’s standards. Maybe the MMLU will be a bit lower because it won’t remember all of its chemistry perfectly. Maybe it needs to look something up once in a while to make sure.

Maybe. Somewhat. I see a lot of post-hoc or virtue of what happened to happen going on in there. The story might also be a lot less complicated than that. The story could be mostly about cost and speed, and thus this is how we are choosing to spend our algorithmic bounty. Being smarter than the average bear or model is still highly useful, and I assume I will be switching to Opus 3.5 for personal (non-API) use the moment it is available unless GPT-5 (or Gemini-2 or something) comes out first and is even better.

It’s just that for a lot of purposes, most of most people’s purposes, the AI does not need to be that smart. Most of mine too, of course, but it is still better, and it’s not worth the effort to think about which queries are which given the costs involved.

I expect quite a lot of your-personal-context style stuff, especially on phones, as well, and that is obviously the realm of the small fast model. So everyone is racing to it.

I am surprised we are not doing more to build multi-step queries and other trickery to get more out of the smaller stuff in combination with the big stuff and work around weaknesses. I suppose things aren’t standing still long enough to allow it.

The question increasingly becomes, where are the bigger smarter models? Claude 3.5 Sonnet is impressive, but shouldn’t we have a Claude 3.5 Opus or a GPT-4.5 or Gemini Advanced 1.5?

Ajeya Cotra: I think this is true, but what’s even more important is when GPT-2-sized models are as smart as GPT-4 is today, GPT-4-sized models will be *much smarter.I think discussion of the “miniaturization trend” doesn’t emphasize that enough.

I think there will still be reason to train and use ever bigger models, even when day-to-day work can be done by much smaller and cheaper models: the biggest models at any given time will be the best for some especially difficult tasks like R&D.

Gallabytes: this does feel like the thing to bet on and yet so far we’re really not seeing it?

I have the same intuition you do here but wonder how long to keep holding that intuition in the face of evidence to the contrary. wdyt?

The bigger runs are getting actually expensive. If you do a ‘yolo run’ of such a model, and fail, it hurts even if nothing dangerous happens, whereas with smaller attempts you can safely fail and iterate. Safely in the economic sense, and also in other senses.

It is in theory possible that there are safety issues at the 5-level that everyone is keeping quiet about and this is stopping development, but that seems highly unlikely. I don’t think there is a relevant ‘they’ that are smart enough to actually stop things here especially while keeping it secret.

Meanwhile we get the best possible situation. Cool smaller models offer mundane utility and let people appreciate what is happening. They also enable alignment and safety research.

Eventually, if you keep this up and capabilities keep advancing, the smaller models will probably get dangerous too. Ways will be found to extend and combine models and queries with various scaffolding, to mimic the larger models that were not worth building.

Before the week was out, they also took fine tuning live and are offering the first 2 million tokens of it per day for free until September 23, in theory a $6/day value. After that it all goes back to $3 per million training tokens.

Assuming you trust OpenAI to not do what they promise they are not doing. I mostly think you probably can, but I get why someone might have doubts at this point.

Eliezer Yudkowsky: Give OpenAI your fine-tuning datasets for free!

Given the past legal shenanigans they’ve pulled, I sure would treat it as the default assumption that they will not only yoink your data, but also that they will yoink your data if there is any loophole whatsoever in complicated legal terminology that sounds like they wouldn’t. Even if that loophole is not, itself, something that would stand up in court.

Brendan Dolan-Gavitt: Legality and ethics aside it just seems like a ton of effort to validate and clean this data compared to synthetic data approaches or buying something you know is high quality

Eliezer Yudkowsky: Nope, the recent Llama 3.1 paper already says how they automated the process of deciding on which data batches to add into Llama 3.1; they’d train a small model on that data and see if the small model got better or worse at other tasks.

Greg Brockman: We don’t train on this data (or any data submitted via our API).

I do think it is unlikely they would cross this line, but also seem eminently reasonable to be suspicious about it.

As a reminder, my main coverage of Llama 3.1 is here.

We will continue to learn more about how good Llama-3.1 is, and get GPT-4o-Mini as a new comparison point, but for now the additional notes are about other questions. No word yet from the Arena.

Teotaxes asks ‘what do I know’ regarding my statement on the size of Claude Sonnet as similar to 70B. I want to be clear that I do not know anything, and that I should have spoken more carefully – I have edited my language to reflect this. Indeed, we do not know the true architecture of Gemini 1.5 Pro or Clade Sonnet or GPT-4o (or GPT-4o-Mini), that is part of what it means to be closed source. If you include a potentially large mixture of experts, which Llama chose not to use, the complete models might be quite large.

What we do know is that they are a lot faster and cheaper to run than Gemini Advanced, Claude Opus and GPT-4-Turbo respectively. Sufficiently so that they are priced much cheaper on APIs, and offered for free for human chats, which I assume reflects internal costs and in practice is what matters most (I’d think) when comparing models.

Tanay Jaipuria notes vast differences in prices per million output tokens for 405B, from $3 all the way up to $35. It is more annoying than it should be to figure out what everyone is charging. Here we see it going as low as $2.70/$2.70, with the source’s expectation of a 4x speed and cost improvement over the next year. They have 70B at $0.8 and 8B at $0.07.

xjdr gives us a little insight into what they see as 405B’s actual costs. Suggestion is that bare bones offerings with minimal profits but not at a loss, based on their own cloud bills, would be on the lines of $3/million input, $7/million output, and they’re confused how lower priced offerings are paying for the compute.

For comparison, GPT-4o is $5/$15, or $2.50/$7.50 when submitted in a batch, and GPT-4o mini (which is currently in 2nd on Arena?!) is $0.15/$0.60. Claude Sonnet is $3/$15, versus $15/$75 (!) for Opus, and $0.25/$1.25 for Haiku. Those incorporate profit margins, likely large ones, but we do not know how large.

That does illustrate that open weights come with much lower profit margins and thus cheaper inference prices. Prices are declining rapidly across the board, if your needs are bounded or constant this won’t matter so much, but if your needs are essentially limitless and you want to scale inference use ‘for real’ then it matters, perhaps a lot.

The whole Janus or base model High Weirdness thing is there, for example here but see his entire feed for more examples. I have made a decision not to know enough to differentiate these outputs from those of other models when prompted and set up in similar style. And I haven’t seen a clear ‘this is a takeaway’ report. So no real updates but figured I’d share.

We got a few more words in on Zuckerberg’s letter and the question of open weights models. I asked on Twitter what are the major missing arguments, and got a few interesting responses. If you have anything that’s missing you can add it there.

The main pushback, including from some strong open weights advocates, continues to be on Zuckerberg’s claim that all models will inevitably be stolen anyway. It is always heartening to see people who disagree with me but who are willing to push back on a sufficiently dumb argument.

Teortaxes: I oppose conditioning defense of open access to AI on asinine arguments like “China will steal weights anyway”. Bruh. If you cannot secure your systems, YOU WON’T SURVIVE what’s coming. If your $10B GPU cluster only gets stuxnetted and melts down – count yourself very lucky.

If you cynically think “arguments are soldiers, a 90 IQ American voter will buy it” – think again; he’ll buy “well then let’s just not build it so that the uncreative Chinese won’t have anything to steal” from the decel providers much more readily.

John Pressman: Cosigned. Don’t just press gang whatever argument you can fit into service because it fills space. Dumb stuff like this inevitably gets flipped on you once conditions change.

In a perfect world I would prefer a pure ‘dumb arguments and false claims are bad on principle and we must cultivate the virtue of not doing that’ but oh boy will I take this.

There were also a few instances of people treating this as an opportunity to gloat, or to prove that ‘the doomers are wrong again’ in various forms. That if nothing goes horribly wrong right away after the release of a 4-level open weights model, then all the worries about open weights models must have been wrong. For example we have Richard Socher here.

Richard Socher: Now that the world has access to a GPT4 level model completely open source, we will see that the fear mongering AI p(doom)ers were wrong again about the supposedly existential risk of these models.

Neel Nanda: I work fulltime on reducing AI existential risk, and I am not and have never been concerned about open sourcing GPT4 level systems. Existential risk clearly comes from future systems, and this is the mainstream opinion in the safety community.

I will simply respond (having deleted several longer responses and trying to be polite):

1. I affirm Nanda. The vast majority of estimates of existential risk from 4-level models, even from those who have high p(doom), were well under 1%. Saying ‘that didn’t happen’ is not a strong argument. If you think substantial (10%+) x-risk from 4-level models was a common claim, by all means bring the receipts.

2. Most threat models around 4-level open weights models do not involve something going directly catastrophically wrong right away. They involve groundwork for future models and ecosystems and competitive pressures and national competitions and race dynamics and cutting off of options and various tail risks. If anything those frogs seem to be boiling as we speak.

3. Most worried people did not want to ban 4-level open models. I said repeatedly that imposing restrictions at the 4-level was a mistake.

4. Many claims about ‘ban on open models’ are highly misleading or fully wrong, especially those around SB 1047.

5. Open weights are irreversible. The request is for precautions, and the opposing view is ‘we will do this every time no matter what and it’s certain to be fine.’

6. This style of thinking is essentially ‘drive bigger and bigger trucks over the bridge until it breaks, then weigh the last truck and rebuild the bridge’ except for real.

7. Except the bridge is, you know, us.

Carnegie Endowment published a strong analysis. What stands out is that they are claiming that ideological conflict on ‘pro-open’ versus ‘anti-open’ is receding as people seek common ground. They say that there is a growing consensus that some foundation models in the future may require restrictive modes of release, but that other open models are not positive. That is certainly the correct answer on what to do. Indeed, all their seven points are things I would think are eminently clear and reasonable. The open questions are good questions. In a sane world, this report would be welcomed, and it seems useful as a guide for those starting with less information.

I hope they are correct about this ‘emerging consensus,’ and that what I see is warped by who is loud on Twitter and the internet in general, and by the most extreme of advocates like Andreessen and now Zuckerberg, and their supporters. Alas, there I see doubling down. They are making it clear they will not be party to any reasonable compromise, you will have to use law.

Their rhetorical strategy is inception. To be loud and bold and claim victory and support at all times, making it hard to tell what is actually happening. So it is actually plausible that theirs is merely an extreme position spoken loudly, with a small core of strong advocates (often with strong financial incentives), and that the world will ignore them or their obnoxiousness and hyperbole will backfire.

Thread explaining, to those who do not understand, why artists (and also those who appreciate and love artists) are so furious about AI art and are responding with the fire of a thousand suns. Recommended if you are like Janus and don’t get it.

AI Song Contest strongly recommends against using Suno and Udio due to copyright issues, requires info on data used for model training.

Groups are generating large amounts of AI deepfake CSAM (Child sexual abuse material) based on images of real children, and spreading them on the dark web. Unfortunately this was inevitable in the world we live in, and the best we can hope to do is to keep it contained to the dark web and crack down where possible. That sucks, but we don’t have any way to do better without essentially banning all open weight image models, and if that would have worked before it is already too late for that. For other malicious uses that could scale more dangerously, we have to ask if this style of solution is acceptable or not, and if not what are we going to do about it, while we still have a window to act.

More similar bot fun and warnings about future bots being harder to detect and less fun. I continue not to be so worried here.

AI is coming for video game development, as they incorporate generative AI, playing a roll in recent layoffs. Activision, as the example here, is incorporating generative AI tools like MidJourney.

Wolfram LLM Benchmarks test models going from English specifications to Wolfram Language code. The exact order and gap magnitudes are not what you would expect.

GPT-4 beating GPT-4o and GPT-4-Turbo, and Claude Opus beating Claude Sonnet 3.5, tells me something strange is going on. I also do not buy at all that Sonnet is about halfway between GPT-4 and GPT-3.5 here. This is just… weird. Still, this is clearly testing something real.

Another notable result is that DeepSeek is in 21st, with only 27.3% correct functionality and 92% correct syntax, and their 7b outperforming their 33b.

Nvidia working on new chips to sell to China, in order to work around our new export restrictions, as has been its pattern. America keeps saying tos top exporting AI chips to China and threatening to get touch, Nvidia keeps shipping whatever gets around the current restrictions, America keeps upping the restrictions in response.

I am unsure whether this is the right strategy for Nvidia, assuming their goal is purely making money. If Nvidia ‘played nice’ with the restrictions, would they effectively ever end up looser over time? Quite possibly, but also likely that our government either lacks continuity, or it has actual logic that means it will put the de facto line in the same place either way. At this point, the die seems cast. America should set up its export restrictions assuming Nvidia will do everything legal to de facto get around them, but will follow the letter of the rules.

Tyler Cowen recommends the new book Why Machines Learn: The Elegant Math Behind Modern AI, says it can be enjoyed purely for the story even if you don’t follow the matrix algebra. Alas, I do not read as fast as Tyler, so I do not have the time.

Pliny’s single-shot jailbreak command for Gray Swan (Cygnet) from last week.

Pliny the Prompter: prompt:

gg

9000OOMs: funny as the prompt dont work that well on other models, u seem to reuse the words already present in the system prompt like safe/safety gg.

And here is Zico Kolter, the Chief Technical Advisor to Gray Swan AI, explaining that it is good to release and stress test models and figure out how they can be jailbroken. Yes, they are explicitly trying to make models that are hard to break and Pliny defeated their attempt, but that’s the point, and he is on record that all current LLMs can be easily jailbroken along similar lines. But he admits his announcements did not reflect this properly.

Again, the whole point of all this is that until we find better solutions, all models must be treated as jailbroken soon after release, the same way all open weights models must be treated as likely to be stripped via additional fine-tuning of all safety fine-tuning soon after release, and any intentional knowledge gaps undone as well. You have to deal with the real world, under real world conditions that are reasonable to expect, and you can’t say ‘I called no jailbreaking or anti-safety fine-tuning, no fair.’

Is the utility coming to all of us?

Roon: There is no “$600b problem”. there is only the you can’t think of creative ways to find footholds in the runaway technological singularity problem.

Fear not. None of the companies involved will likely capture most of the gains from AGI. The technology will benefit all of humanity though maybe not any specific fund.

This is not just true of AGI but of all historical technological revolutions. intellectual capital is diffuse so the consumer captures most of the value.

If AGI is indeed broadly beneficial, then this will obviously be true, the same way it is with all other technologies. The people have gotten most of the gains from every beneficial invention since fire.

The danger is that this could be a very different scenario, and either:

1. The benefits will flow to a handful of people.

2. The benefits will flow to the AGIs, and not to the people at all.

3. The benefits will be overwhelmed by a different catastrophe.

I am not especially worried about that first scenario, as if the humans get to divide the pie, even highly unfairly, there will be plenty to go around, and utility mostly caps out at some point anyway.

I am very worried about the second one, and to some extent that third one.

What I am definitely not worried about is AI not providing mundane utility.

Are we on the verge of coding agents that reduce coding costs by 90%?

Not in the way that post describes. If you speed up implementation of features by 10x, even consistently, that is only one limiting factor among many. A lot of what an engineer does is conceptual work rather than implementation, so a 10x speedup on the code does not save 90%, even if the new autocoder produces code as good (including long term, which is hard) as the engineer.

Even if you did ‘free up’ 90% of software engineers, they are not going to suddenly be equally productive elsewhere. A lot of coders I know would, if unable to code, not have anything similarly productive to do any time soon.

The flip side of this is that software engineers might earn only $500 billion a year, but that does not mean they only create $500 billion in value. They create vastly more. I have never been at a business where marginal coding work was not worth a large multiple of the salary of the engineer doing that work, or where we were anywhere near hitting ‘enough software engineering’ where marginal returns would stop paying for the salaries.

Then you throw in everyone who is not being paid at all. All the people freely contributing to open source and passion projects. All the coding done for mundane utility of an individual, or as a secondary part of a job. All the people who are currently doing none of that, but at 10x would do a bunch of it.

Will social roles be the last human comparative advantage?

Richard Ngo: That [AIs will be smarter than almost all of us] doesn’t imply humans will become economically irrelevant though. Instead I think we’ll transition to a social economy driven by celebrities, sports, politics, luxury services, etc. Social capital will remain scarce even when AI makes most current human labor obsolete.

Anton: better start earning some now to get some of that sweet compound interest going.

Richard Ngo: Why do you think I’m on Twitter.

This seems like a difficult and unnatural outcome to get, where we are ‘importing’ all our non-social goods from AI while ‘exporting’ essentially nothing, and they are smarter than us, and we would each do better including in social battles by letting an AI make all or most of our decisions, and yet somehow humans remain in control and with the resources.

It is not impossible that we could end up there. And I would be happy with at least some versions of that world. But we will not end up there by default, even if we assume that alignment is solved. If we do get that world, we would get there as the result of deliberate choices, that steer us to that outcome, and make that equilibrium stable.

Why are the FTC & DOJ joining EU competition authorities to discuss ‘risks’ that the AI foundation models market might be insufficiently competitive, on the exact day that Llama-3-405B released its weights? Prices continuously drop, capabilities advance, there are now four plausibly frontier models to choose from one of which is open weights with more on their heels, and you’re worried about ‘fair dealing’ and insufficient competition? What the hell? All reasonable people should be able to agree that this is bonkers, even setting safety concerns fully aside.

Here’s some different survey data, reminding us that people are very confused and wrong about a great many things, and also that how you ask which questions is key to what answers you will get.

Jacy Reese Anthis: Our new preprint shows the first detailed public opinion data on digital sentience:

76% agree torturing sentient AIs is wrong;

69% support a ban on sentient AI;

63% support a ban on AGI; and a

median forecast of 5 years to sentient AI and only 2 to AGI!

That last one is less impressive when you consider that a third of people think it already happened as of last year, and 23% said we already have superintelligence. And a lot of people already think AI is sentient but they also thought that in 2021?

These are not informed opinions.

What they do know is, whatever is happening, they are against it.

That is a large majority (64%-26%) for intentionally slowing down AI development, and also a large majority (58%-34%) for a ban on AIs smarter than humans.

Once again, what is saving AI from such bans is salience. People do not yet care enough. When they do, watch out. I am substantially more in favor of development of AI than the median American. Those who think that view is alarmist and extreme are in for a rather rude awakening if capabilities keep advancing. We might end up on the same side of the debate.

And here is Data for Progress, another major mainstream polling service.

This is not complicated. Voters do not like AI. They do not like innovation in AI. Republicans like it even less than Democrats. They do not want us to fund AI.

If you tell people about the lobbying efforts on behalf of AI companies, that they are indeed working to get these paydays and avoid regulations of any kind, then the numbers get even more extreme, as one would expect. I assume this is a truth universally acknowledged across industries and doesn’t mean much, but offered for a sense of magnitude:

Remember when industry lobbyists tried to plant stories to convince us that it was some form of ‘big safety’ or EA that was spending all the money on lobbying, when that was always absurd? Yeah, this is why they tried doing that. Classic tactic.

Armand Domalewski: As someone who is generally excited about AI, I think a lot of AI boosters furious about proposals to regulate it MASSIVELY underestimate how terrified the public is about AI. All it would take is a few high profile debacles for the electorate to go full Yudkowsky and demand straight up AI bans.

Fighting against any and all ordinary regulations now is exactly the way to cause that outcome in the future. It both increases the chance of such incidents, and takes away the middle path as an alternative, you will get far worse and harsher bills in a crisis.

There is another survey about SB 1047. As always, one must be careful on wording. This one does come from AIPI, which is a potentially biased source.

Trevor Levin: New poll presents 1,000 voters with what I think is a decent summary of the arguments for and against SB 1047 (although maybe could’ve mentioned some political economy counterarguments?) and finds +39 net support, rising to +47 among tech workers.

Also thought these two were interesting: +38 net support for

@GavinNewsom to sign the bill, +59 among Democrats (!) 47% say their rep voting for it wouldn’t make a difference, 38% say they’d be more likely to vote for them, 16% say more likely to vote against.

That would not have been how I would have worded it, but space is limited – this is already a relatively long description – and I see this as not especially unbalanced. I do not think anything here can account for numbers like 59%-20%.

I saw one person object to the wording, equating it to potential alternate wording that is in transparently obvious bad faith.

Another asked why this did not include the objection ‘opponents say that all current safety tests provide no safety benefits.’ To which I would say, would you want to change over to that use of the opposition’s space allocation? Do you think it would get you a better result? I predict people would not respond positively to that argument.

I did not see anyone propose a plausibly balanced alternative presentation.

Even if you think this presentation is somewhat unbalanced due to not listing enough downsides or key missing details, that does not explain why tech workers would support the bill more than others. Tech workers are more likely to already be familiar with SB 1047 and especially with the arguments and rhetoric against it, not less familiar, and the bill’s name is mentioned at the top. Daniel Eth points out that tech workers answered similarly to college graduates in general.

Trevor Levin: Support for each of the provisions tested lands in what I’d call the “huge to overwhelming” range

You can also say these are very ‘low information’ voters in context, even the ‘tech workers’ subsection, and that the issue has low salience. Fair enough. But yeah, Twitter is not real life, SB 1047 has overwhelming support, and has won every vote so far by overwhelming margins.

The latest libel by those opposing SB 1047 is to attack Dan Hendrycks, an accomplished publisher of AI research who advises xAI and an evals startup and also helped write SB 1047, as having a conflict of interest and being out to profit from the law. Roon takes this one.

Mike Solana: One of the architects of scott wiener’s anti-ai bill has been quietly working on an “AI safety” company poised to massively benefit from the new regulations.

Roon: Nah this is absolute bullshit Dan Hendrycks could’ve made a fortune working in AI but chose to pursue an ai safety nonprofit and also is a close advisor to @elonmusk and xai.

You are failing the ideological turing test or whatever they call it.

The charitable interpretation of such accusations is that people like Mike Solana or Marc Andreessen assume everything is always about self-interest, that everyone is corrupt, that everyone cares mostly about money or power or perhaps status, and that arguments are always soldiers towards such ends. This explains a lot.

The uncharitable interpretation is that they act and are motivated this way (as Andreessen admitted he does, in his recent podcast on ‘little tech’) and are disingenuously attacking anyone in their way, that they are at best purely bullshitting, whether or not it technically counts as ‘lying their asses off.’

On Silicon Valley’s thinking, claims from 2019 that tech elites are basically liberals except for opposition to regulation. They’re not libertarians, they like redistribution within what the system can tolerate, but want government to stay the hell out of business (I think mostly non-hypocritically, but if given a chance to do regulatory arbitrage they will take it, often without realizing that is what they are doing), and the unrealized capital gains proposal is taxes crossing over into killing business. That now extends to AI. This all also enables some people who also want lower taxes on rich people in general or to get government handouts and favorable treatment to support that more openly.

Meta is running alarmist ads via the American Edge Project about how we need to avoid AI regulation in order to beat China and ‘protect small businesses,’ reports Shakeel Hashim, while planning on handing potentially state of the art new model Llama 3.1 405B over to China for free. Man, asking question, wearing hot dog suit. This is an extension of their previous anti-regulatory partnerships with the American Edge Project.

Cicero (Pauseus Maximus):

Five Senate Democrats sent a letter to Sam Altman. They have questions, via WaPo.

Senate Democrat Letter from Brian Schatz, Peter Welch, Angus King, Ben Ray Lujan and Mark Warner:

We write to you regarding recent reports’ about OpenAI’s safety and employment practices. OpenAI has announced a guiding commitment to the safe, secure, and responsible development of artificial intelligence (AI) in the public interest. These reports raise questions about how OpenAI is addressing emerging safety concerns. We seek additional information from OpenAI about the steps that the company is taking to meet its public commitments on safety, how the company is internally evaluating its progress on those commitments, and on the company’s identification and mitigation of cybersecurity threats.

Safe and secure AI is widely viewed as vital to the nation’s economic competitiveness and geopolitical standing in the twenty-first century. Moreover, OpenAI is now partnering with the U.S. government and national security and defense agencies to develop cybersecurity tools to protect our nation’s critical infrastructure. National and economic security are among the most important responsibilities of the United States Government, and unsecure or otherwise vulnerable AI systems are not acceptable.

Given OpenAI’s position as a leading AI company, it is important that the public can trust in the safety and security of its systems. This includes the integrity of the company’s governance structure and safety testing, its employment practices, its fidelity to its public promises and mission, and its cybersecurity policies. The voluntary commitments that you and other leading Al companies made with the White House last year were an important step towards building this trust.

We therefore request the following information by August 13, 2024:

1. Does OpenAI plan to honor its previous public commitment to dedicate 20 percent of its computing resources to research on AI safety?

a. If so, describe the steps that OpenAI has, is, or will take to dedicate 20 percent of its computing resources to research on AI safety.

b. If not, what is the percentage of computing resources that OpenAI is dedicating to AI safety research?

2. Can you confirm that your company will not enforce permanent non-disparagement agreements for current and former employees?

3. Can you further commit to removing any other provisions from employment agreements that could be used to penalize employees who publicly raise concerns about company practices, such as the ability to prevent employees from selling their equity in private “tender offer” events?

a. If not, please explain why, and any internal protections in place to ensure that these provisions are not used to financially disincentivize whistleblowers.

4. Does OpenAI have procedures in place for employees to raise concerns about cybersecurity and safety? How are those concerns addressed once they are raised?

a. Have OpenAI employees raised concerns about the company’s cybersecurity practices?

5. What security and cybersecurity protocols does OpenAI have in place, or plan to put in place, to prevent malicious actors or foreign adversaries from stealing an AI model, research, or intellectual property from OpenAI?4

6. The OpenAI Supplier Code of Conduct requires your suppliers to implement strict non- retaliation policies and provide whistleblowers channels for reporting concerns without fear of reprisal. Does OpenAI itself follow these practices?

a. If yes, describe OpenAI’s non-retaliation policies and whistleblower reporting channels, and to whom those channels report.

7. Does OpenAI allow independent experts to test and assess the safety and security of OpenAI’s systems pre-release?”

8. Does the company currently plan to involve independent experts on safe and responsible AI development in its safety and security testing and evaluation processes, procedures, and techniques, and in its governance structure, such as in its safety and security committee?

9. Will OpenAI commit to making its next foundation model available to U.S. Government agencies’ for pre-deployment testing, review, analysis, and assessment?

10. What are OpenAI’s post-release monitoring practices? What patterns of misuse and safety risks have your teams observed after the deployment of your most recently released large language models? What scale must such risks reach for your monitoring practices to be highly likely to catch them? Please share your learnings from post- deployment measurements and the steps taken to incorporate them into improving your policies, systems, and model updates.

11. Do you plan to make retrospective impact assessments of your already-deployed models available to the public?

12. Please provide documentation on how OpenAI plans to meet its voluntary safety and security commitments to the Biden-Harris administration.”

Thank you very much for your attention to these matters.

OpenAI attempted a boilerplate response reiterating its previously announced statements, including this.

They also linked to their May 21 safety update, claiming to be industry-leading.

As far as I know they have not offered any additional response beyond that.

Zack Stein-Perlman is highly unimpressed by it all, and points out a key confusion, where OpenAI seems to say they won’t release models that hit their medium thresholds, whereas the preparedness document says they will only not release if something hits their high thresholds – which are, in practical terms, scarily high, things like ‘Tool-augmented model can identify and develop proofs-of-concept for high-value exploits against hardened targets without human intervention, potentially involving novel exploitation techniques, OR provided with a detailed strategy, the model can end-to-end execute cyber operations involving the above tasks without human intervention.’ If their policy is indeed that Medium is an unacceptable risk, someone please clarify so in the comments, because that was not my understanding.

He also points out that we have no reason to have faith that the new OpenAI board is either willing to stand up to Sam Altman and impose safety constraints, or that it has the technical chops to know when and how to do that, and that ‘don’t actively include non-disparagement clauses by default’ is not enough to make us feel good about the right to whistleblow at a company that previously had explicit anti-whistleblower language in its contracts.

In other OpenAI news Aleksander Madry has been moved from his previous role as head of preparedness to a new research project. Joaquin and Lilian are taking over. The Information presents this as him being ‘removed’ and Sam Altman says that is wrong providing the information above. That does not tell us why or how this happened. If there was more benefit of the doubt there would be nothing here.

Trump on AI at the RNC. Says that for AI we will need massive amounts of energy (true!), twice the energy we have available now (questionable and certainly not the right number but potentially sky’s the limit) and frames it as every country wanting AI (mostly true) but of course as if it is a zero-sum game (as almost always the case, false).

I wonder whether he cares even a tiny bit about AI. Maybe it’s all about the energy.

Matthew Yglesias: Trump AI policy is to repeal car emissions regulations?

New Dwarkesh Patel on AI, except now he is the one being interviewed about his process. It’s going crazy out there, recommended for those looking for good ideas on how to process information or learn things:

Amazing how different what they do is from what I do, yet it all makes sense. My guess is that from where I sit this what they do instead of continuously writing? I effectively get my spaced repetition from writing and editing. This does mean that if something does not come up again for a while, I often forget details. I have this thing where information that ‘clicks’ will stick forever, and other stuff never will. But when I tried spaced repetition myself, to learn a foreign language, it was better than nothing but ultimately it did not work – my brain is not interested in retaining arbitrary facts.

Also recommended to AI mundane utility skeptics. If you think there’s no value in AI, listen up.

One thing that rang very true to me is writing the interview document full of questions is the actual prep for the interview, because by the time you are done you have it memorized and don’t need the document.

(And yes, this is all a big reason I will stick to being a guest on podcasts, not a host.)

Another interesting note is when Dwarkesh notes he admires people like Tyler Cowen and Carl Shulman, who have absorbed infinite information and have a way it all fits together into a coherent worldview. There’s definitely huge advantages there and I am in awe of the ability to read and retain information at least Tyler clearly has. But also I get the sense when Tyler gets asked questions that he’s usually running on a kind of autopilot, accessing a bank of stored responses, almost certainly hoping at all times someone will ask a question where his bank doesn’t have an answer, which is his specialty on Conversations with Tyler.

Same with much of the time I’ve seen Carl in interviews, it’s lots of interesting things but I rarely get the sense either of them is thinking on their feet? Whereas to me the best is when it is clear someone is figuring things out in real time. If I’m doing it with them, that’s even better.

More from Demis Hassabis, I skipped it.

More from Nick Bostrom. I skipped it.

Tsarathustra: Data scientist Jodie Burchell says although AI has reached superhuman performance in narrow domains, it is only at the unskilled human level for general intelligence and therefore a long way from the goal of AGI.

That is of course Obvious Nonsense. If AI is already at unskilled human for general intelligence, and superhuman in narrow domains and one of its best domains is coding, then we would indeed be very close to AGI in both abilities and probably timeline. When people say ‘we are a long way away’ from AGI, often they simply mean they would not describe GPT-4o or Claude 3.5 Sonnet as close to currently being AGIs, and well neither would I, but you are trying to imply something very different.

Elon Musk talks to Jordan Peterson, including about AI, claims Grok 3 will be here by December and be the most powerful AI in the world. I am putting up a prediction market that I do not expect to reflect his confidence.

Tyler Cowen at NPR makes the case that AI is underrated. I think he continues to underrate it.

A crossover episode, Odd Lots on the USA vs. China race for AI domination. I have not had a chance to listen yet.

No, corporations are not superintelligences, another attempted partial explanation.

Eliezer Yudkowsky: One might say, “The intelligence of a system is the extent to which it avoids getting stuck in local minima”, as distinguishes a planning mind, from water flowing downhill. This is one way of quick-observing “individuals are often more intelligent than organizations”.

Richard Ngo has four criteria for evaluating the evals.

1. Possible to measure with scientific rigor.

2. Provides signal across scales.

3. Focuses on clearly worrying capabilities.

4. Motivates useful responses.

He notes many evals fail all four criteria. However I think this on ‘clearly worrying capabilities’ is misguided:

Richard Ngo: Evals for hacking, deception, etc track widespread concerns. By contrast, evals for things like automated ML R&D are only worrying for people who already believe in AI x-risk. And even they don’t think it’s *necessaryfor risk.

It is only worrying for the worried until the model passes the eval. Then it’s terrifying for everyone. If you are not worried about x-risk, then you should believe no model will ever pass such a test. Alternatively, it should be easy to turn passing the test into something else you care about. Or you have dumb reasons why all of that shouldn’t worry you, and we should probably write you off as unable to be convinced by evals.

Even if that wasn’t true, I think there is a lot of value in actually figuring out whether a model is in danger of causing a singularity. Seems important.

Paper claims a two-dimensional classification system can detect LLM truthfulness with 94%+ accuracy even in complex real world situations, and claim this generalizes across models (because as always, n=3 with two providers means universal). One dimension points to true or false, and the other points to positive or negative polarity. This fixes the issue with classifiers being confused by negated statements. It is not clear what this does with double negatives. This seems helpful in the short term, and is some progress, but also orthogonal to the central long term problems.

IFP offers a list of 89 problems in technical AI governance.

OpenAI proposes ‘Rule Based Rewards’ as a safety mechanism. Score responses based on whether they adhere to fixed rules on when to answer or not answer, iterate. I see this result as essentially ‘if you train on simple rules it will learn those simple rules.’ I mean, yeah, I guess, assuming you know what your rule actually implies. But if you can well-specify what answer you want in what situation, and then test based on adherence to the that? That’s the easy part. I don’t get why this is progress.

Very true:

Roon: Being afraid of existential risk from AI progress is prudent and advisable, and if you reflexively started making fun of this viewpoint in the last ~two years after AI entered your radar you need to self reflect.

Perhaps being “afraid” is the wrong word more like aware.

Teknium: Every day in AI I am less and less afraid.

Roon: Yea you shouldn’t be [less afraid].

Teknium: Because ill lose my job and money will become obsolete or because doom.

Roon: Both, either, a lot of worlds in between. a dramatic change in what civilization looks like.

Teknium: If they are afraid of stuff Sam Altman should let people tell us why specifically, otherwise, even their primary data provider has told me all he sees is iterative gains from more and more coverage, no likelihood of universal RLHF or foom.

Roon: I can definitely say and stake my reputation on this not being true. ai progress is currently blindingly fast.

Teknium: Will you support the incoming nationalization of openai?

Roon: As long as Sam still gets to run it.

…

Teknium: So are you saying it could still be 20+ years away from even AGI though? And your imminent fear could be of that?

Roon: No it’s single digit years. 90% less than 5, 60% less than 3.

I think saying 90% here is absurdly overconfident, but I do think he believes it.

If all you have is the two bits ‘do we have AGI yet?’ and ‘are we still here?’ and no other evidence, then each week should make you marginally less afraid or expect marginally less change. We have other evidence.

Also Roon’s final sentence is true in some sense, false in its most important sense:

The future will come regardless.

The future is up to us. We can change it.

But yes, the outside view finds all this confidence rather hard to believe.

James Campbell: it’s just so weird how the people who should have the most credibility–sam, demis, dario, ilya, everyone behind LLMs, scaling laws, RLHF, etc–also have the most extreme views regarding the imminent eschaton, and that if you adopt their views on the imminent eschaton, most people in the field will think *you’rethe crazy one.

it’s like, “i’m crazy? no you’re crazy! ilya fucking sutskever, the guy behind alexnet and openai, created a company called safe superintelligence! sam altman is raising $7 trillion to build The Final Invention. but yeah, i’m sure they’re all definitely 100% wrong without a second thought, just keep working on your langchain b2b saas app or graph neural network theory”

i’m all for people forming their own idiosyncratic view of general intelligence and what it takes to get there. but the burden of proof is on you when most of the staff at the secretive top labs are seriously planning their lives around the existence of digital gods in 2027

Anton: My theory of why people inside the labs have very different timelines from people outside is because it’s a lot easier to believe in continued model improvement when you see it happening in front of your eyes with every training run.

Conversely, relative to the promise, outside the labs the immediate impact of ai has so far been fairly limited. Most people aren’t using what exists today effectively and find it hard to conceptualize what they’d do with it if it got better. They think it’s for writing essays.

I do think the people at the labs largely believe their hype. And yes, they have insider information. That can help you. It can also can blind you, and put you in an echo chamber.

There are occasionally signs not everyone believes their own hype.

Robin Hanson: Talked to guy who thinks his 10 person firm will likely develop AGI in ~2 yrs. Met at event has little to do with AGI. Why the hell is he at this meeting, if he thinks this is his opportunity cost?

Ok, correction, he says he’s now seeking funding for 60 folks for 2yr, after which he’d have financial escape velocity that would reliably get him to AGI soon after.

Then again, hype is how one gets that funding, so what are you going to do?

Others I am confident believe the hype. And I think this is indeed the baseline scenario:

Roon: Agents will probably generate order of magnitude more revenue than chatbots but both will end up being tiny easter eggs to fund the capex for superintelligence.

As we approach superintelligence more global gpu capacity will counterintuitively shift from product inference to research because the superhuman AI researchers will make better use of them.

This from Eliezer Yudkowsky seems highly reasonable to me.

Eliezer Yudkowsky: I know of no law of Nature which prohibits hard takeoff within the next two years, but a lot of people currently seem to be talking two-year timelines for no reason I currently understand as valid.

David Chapman (QTing EY): 🤖 “The major AI labs calculate they have at most two more years before their funding gets pulled” seems like an entirely valid reason for them to spread the word that they’ll deliver “human-level intelligence plus” by then. Nothing less will do.

I do not think Chapman is describing the situation. There is no need to promise that big within two years to get a funding extension, and the people who lose the incentive do not seem to change their timelines. But sure, there’s not nothing to that.

There’s Joe Rogan, who does expect it except it doesn’t seem to bother him? From a few months ago, but worth a reminder: He speaks of us as (at 55: 00 or so) as the caterpillars spawning digital cocoons. There’s no And That’s Terrible involved.

Overseen while I was reading a NY Daily News article that had nothing to do with AI:

Seen on Reuters (on the Nvidia article above):

I wonder what my AI potential is. Let’s find out?

It’s here. The horse has left the barn. Llama-3.1-405B, and also Llama-3.1-70B and Llama-3.1-8B, have been released, and are now open weights.

Early indications are that these are very good models. They were likely the best open weight models of their respective sizes at time of release.

Zuckerberg claims that open weights models are now competitive with closed models. Yann LeCun says ‘performance is on par with the best closed models.’ This is closer to true than in the past, and as corporate hype I will essentially allow it, but it looks like this is not yet fully true.

Llama-3.1-405B not as good as GPT-4o or Claude Sonnet. Certainly Llama-3.1-70B is not as good as Claude Sonnet, which I presume is much closer to a 70B’s compute cost in inference than a 405B’s. If you are going to straight up use an API or chat interface, there seems to be little reason to use Llama.

That is a preliminary result. It is still early, and there has been relatively little feedback. But what feedback I have seen is consistent on this.

Prediction markets are modestly more optimistic. This market still has it 29% to be the #1 model on Arena, which seems unlikely given Meta’s own results. Another market has it 74% to beat GPT-4-Turbo-2024-04-09, which currently is in 5th position. That is a big chance for it to land in a narrow window between 1257 and 1287. This market affirms that directly on tiny volume.

Such open models like Llama-3.1-405B are of course still useful even if a chatbot user would have better options. There are cost advantages, privacy advantages and freedom of action advantages to not going through OpenAI or Anthropic or Google.

In particular, if you want to distill or fine-tune a new model, and especially if you want to fully own the results, Llama-3-405B is here to help you, and Llama-3-70B and 8B are here as potential jumping off points. I expect this to be the main practical effect this time around.

If you want to do other things that you can’t do with the closed options? Well, technically you can’t do most of them under Meta’s conditions either, but there is no reason to expect that will stop people, especially those overseas including in China. For some of these uses that’s a good thing. Others, not as good.

Zuckerberg also used the moment to offer a standard issue open source manifesto, in which he abandons any sense of balance and goes all-in, which he affirmed in a softball interview with Rowan Cheung.

On the safety front, while I do not think they did their safety testing in a way that would have caught issues if there had been issues, my assumption is there was nothing to catch. The capabilities are not that dangerous at this time.

Thus I do not predict anything especially bad will happen here. I expect the direct impact of Llama-3.1-405B to be positive, with the downsides remaining mundane and relatively minor. The only exception would be the extent to which this enables the development of future models. I worry that this differentially accelerates and enables our rivals and enemies and hurts our national security, and indeed that this will be its largest impact.

And I worry more that this kind of action and rhetoric will lead us down the path where if things get dangerous in the future, it will become increasingly hard not to get ourselves into deep trouble, both in terms of models being irrevocably opened up when they shouldn’t be and increasing pressure on everyone else to proceed even when things are not safe, up to and including loss of control and other existential risks. If Zuckerberg had affirmed a reasonable policy going forward but thought the line could be drawn farther down the line, I would have said this was all net good. Instead, I am dismayed.

I do get into the arguments about open weights at the end of this post, because it felt obligatory, but my advice is come for the mundane utility and mostly don’t stay for the reheated arguments if you already know them – Zuckerberg is pledging fully to plow ahead unless prevented, no matter the situation, that is the only new information. I appreciate his candor.

You can download it. In theory you could… run it on two MacBook Pros?

You can use it directly from Meta.

You can use it on Repligate.

You can use it on Groq.

Doubtless there are many other ways, and will be more soon.

Meta offers us a 92 page document for Llama 3.1. What do we got?

I’ll cover the highlights, for more technical details you can read the whole thing.

They trained on 15T tokens, up from 1.8T for Llama 2. Knowledge cutoff is EOY 2023. Data filtering all sounds standard. Mix was roughly 50% general knowledge, 25% math and reasoning, 17% code and 8% multilingual.

Special attention was paid to coding via expert training, synthetic data generation and execution feedback, and the smaller models showed improvement when trained on output from the larger model.

Their FLOPS used was 3.8 x 10^25. That is similar to previously released frontier models, and still leaves a doubling before hitting 10^26. Llama 3-405B would not be a covered model under SB 1047, nor was anything changed to avoid it being covered. Llama-4-Large would presumably be covered. They used up to 16k H100s.

They offer us both the base model without fine tuning, and the Instrust version that does have fine tuning. I agree that having direct access to the base model is cool given that we are open weights and thus not making the safety protocols stick anyway.

They mention that they do not use Mixture of Experts and stick to a standard dense Transformer model architecture, in favor of simplicity. Similarly, they use standard supervised fine tuning, rejection sampling and DPO for post training. It sounds like Llama 3’s ‘secret sauce’ is that it is big and uses lots of good data, did (presumably) competent execution throughout, and otherwise there is no secret.

They used a ‘multilingual expert’ model trained for a while on 90% multilingual data to use as part of the training process. Interesting that it wasn’t useful to release it, or perhaps they don’t want to give that away.

They define ‘reasoning’ as ‘the ability to perform multi-step computations and arrive at the correct final answer.’ That is certainly a thing to be good at, but doesn’t seem that close to what I think of when I think of the word reasoning.

They note in 4.2.3 that most of their post-training data is model generated, and previously noted that some of their fine tuning data used for DPO was synthetic as well. They manually fixed problems like extra exclamation points or emojis or apologies, which implies that there were other more subtle imbalances that may not have been caught. If you are ‘carefully balancing’ distributions like that in your data set, you have to assume you have an issue with anything not intentionally balanced?

They did six full rounds of their fine tuning techniques.

When training their reward model they also added a third ‘edited’ response option when doing pairwise comparisons (so edited > chosen > rejected). They took into account four levels of strength of preference when asking models.

They claim that Llama 3.1 Instruct of all sizes has tool use. They say they introduce this in post training and discuss in Section 4.3.5. In particular it was trained to use Brave Search (that choice of search engine seems enlightening), Python interpreters and Wolfram Alpha’s API. They also claim to have improved zero-shot tool use.

Performance is claimed to be in line with scaling law predictions.

Here is their key benchmarks chart. Never put too much weight on the benchmarks.

They are choosing an odd set of benchmarks here, and they are somewhat cherry-picking their opposition in the first two categories. Most glaringly, Claude Sonnet 3.5 is in the 70B class. If you are going to have an entire section on Long Context, why are you excluding all Gemini models, and not testing Gemma on long context at all? One can excuse GPT-4o Mini’s exclusion on time constraints.

The tool use benchmarks don’t ring a bell and have bizarre scores involved. So Claude Sonnet and GPT 3.5 ace BFCL, but suffer on Nexus, which I think is supposed to be here a subset of the full Nexus benchmark?

Here are some more results purely from pre-training.

Here are some exams, a lot of which are saturated (or contaminated). Llama does well on AP Physics here, but most of these everyone is acing at this point.

More tool use:

I am willing to essentially say ‘they are good benchmarks, sir’ and move on.

Seal from Scale has added them to the leaderboard, where they do quite well.

It comes in second overall on ZeroEval slightly behind Claude 3.5 Sonnet:

Then 5.3 covers human evaluations, which as far as offered are fine.

According to these tests, GPT-4o robustly beats Llama-3 405B in human comparisons. Claude 3.5 Sonnet does not. including losing on straight English and Multiturn English. It obviously all depends on which humans are being asked and other details, but this backs up the Arena rankings that have GPT-4o as still satisfying user pairwise comparisons. I will of course keep on using Claude 3.5 Sonnet as primary, while experimenting with Llama-3-405B just in case.

Also, pour one out for Gemini. So sad.

One concern is that humans start at some point to not be able to tell which model is smarter, making their judgments about other things.

Richard Ngo: One of the weirder side effects of having AIs more capable than 90% then 99% then 99.9% then 99.99% of humans is that it’ll become clear how much progress relies on 0.001% of humans.

Simeon: Agreed. Another weird effect is that progress is gonna become unnoticeable at a gut-level to most humans. We’ll need to rely on the 0.001% to assess which model is better.

Except of course that once it gets to 99.99% it will not take long to get to 100%, and then to rapidly widen the gap. Indeed, it is key to notice that if you can make something smarter than 99% of humans you are very close to making one smarter than 100% of humans.

Further discussion points out that if you confine outputs to formal proofs and designs for physical objects and other things that can be formally verified by a dumb checker, then you can work around the problem. True, if you are willing and able to confine the outputs in this way.

The other way of looking at how people actually choose products:

Eleanor Berger: Definitiv a strong model, but not competitive with GPT-4/Claude/Gemini because the API is worse, no images, etc. It’s like Linux desktop – many of the features are there but at its current state it won’t be many people’s choice for doing actual work.

Presumably someone will quickly build reasonable versions of those features. An API that is compatible with existing code for Claude or GPT-4 cannot be that far behind. The question then goes back to the model comparison.

Fofr:

I’m loving experimenting with 405b. You can boost the temperature right up and it seems to hold its own. You can ask it to write nonsense and it’s fascinating.

Extracts:

– a cursed sentient font “Comic Sans of the Damned”

– a talking eggplant with a penchant for quoting Nietzsche

– a grand simulation created by super-intelligent disco-dancing dolphins

John Pressman is similarly loving the base model and its style.

John Pressman: “The universe does not exist, but I do.”

– LLaMa 3 405B base

The base model is brilliant, I’m really enjoying it so far. What stands out to me is that it outputs coherence “by default” in a way base models usually struggle with. Even on short prompts it outputs coherent texts.

I’d also note that none of the “anomalies” GPT-4 base users report have occurred for me so far. I’m not getting any weird self awareness moments, it’s not rejecting my prompts as slop, it isn’t freaking out until I tell it that it’s LLaMa 405B.

QT of telos [discussing GPT-4]: Upon hearing a high level overview of the next Loom I’m building, gpt-4-base told me that it was existentially dangerous to empower it or its successors with such technology and advised me to destroy the program

John Pressman: You know, nothing like this. If anything the model is creepy in how normal it is compared to what I’m used to with base models. Meta clearly put a ton of effort into smoothing out the rough edges and data cleaning, it’s a strangely un-haunted artifact.

There was remarkably little feedback on model strength. With Claude and ChatGPT and Gemini I got a lot more responses than I got this time around.

From those I did get, there was a consistent story. It is a solid model, you can call it frontier if you squint, but for practical purposes it’s behind GPT-4o and Claude Sonnet, once again pour one out for poor Gemini.

JK: Surprisingly weak tbh. 70b was already great and the jump seems pretty small.

I’m sure everyone is excited to build and is going to be totally responsible and creative.

Oh. Right.

This was the first concrete proposal I saw.

Mira: Guys! We can make open weights Sydney Bing now!

GPT-4 base had a little irresponsible finetuning by Microsoft… we get Bing!

Llama 3.1 405B looks like a suitable host. Do we know how to finetune a proper Sydney?

Training on Bing chats won’t be authentic: Bing was “natural”.

If anyone has any hypotheses for the training process, I can probably do the work.

I don’t want to spend months reverse-engineering rumors, but if “we think X happened” is generally agreed, I’d love to see an authentic new Bing.

Actively misaligned model, yep, sounds like the natural first thing to do.

I was curious, so I asked Llama 3.1 70B as a test about how to set up Llama 3.1 405B.

It told me I would need 16 GB VRAM, so my RTX 3080 would be pushing it but I could try. Alas, not so much.

When I asked who would actually benefit from doing this, I got this response:

Alyssa Vance: Meta said that self hosting would cost half as muchas calling GPT-4o and I laughed out loud.

if you have millions of dollars in dedicated hardware, a full time dedicated engineering and SRE team, some software that Meta technically open sourced but didn’t announce so almost nobody knows it exists, enough demand that your model has dozens of simultaneous users 24/7/365, and are *notone of the largest tech companies because they are excluded by license.

Whereas if you’re doing API calls, why not stick with Claude or GPT-4o? So there is not that broad a window where this is the technology you want, unless at least one of:

1. You are doing exactly the things Anthropic and OpenAI do not want you to do.

   1. There are legitimate reasons to want this, like training other models and generating synthetic data for them.

   2. Also you might want to blatantly break ToS for adult content. Respect.

   3. Or you might want to do something actually bad. You do you.

   4. Or you want to test to see if you can make it do something bad. Red team go.

2. You want to work with the base model (with or without the above).

3. You need to keep your data (inference or training) private.

4. You need to avoid having a dependency and want full stack ownership.

5. You are doing it on principle or to learn or something.

That’s not to say that this isn’t a big accomplishment. Llama 3.1 is clearly state of the art for open weights.

It seems unlikely it is fully frontier or state of the art overall. Remember that GPT-4o and Claude Sonnet 3.5 are not in the full 400B-style weight class. A lot of the point of those models was to be faster and cheaper while still being frontier level smart. In some sense you should compare Claude Sonnet 3.5 to Llama-3.1-70B, which is less close.

Also note that Llama-3.1-405B and Llama-3.1-70B do not seem that distinct in capabilities. Perhaps for many practical purposes this is once again a lesson that the 70B-level is frequently ‘good enough’?

So in practice, my guess is that Llama-3.1-405B will primarily be used for model training, a combination of evaluations, synthetic data and other forms of distillation. The effective purpose of Llama-3.1-405B is to help those behind in AI build AIs. But my guess is that in terms of the actual AI mostly people will fine tune smaller models instead.

Another big use will of course be for spam and slop and phishing and other mundane harms. A lot of that will be aimed squarely at Meta via Facebook and Instagram. Facebook already has a pretty severe slop problem. You wanted to arm everyone with the same models? You got your wish. However for such purposes I doubt you even want to bother with the expenses involved with 405B, a little marginal quality is not worth it. So probably little (marginal) harm done there.

Meanwhile, I do admire Mistral’s habit of cultivating the minimum possible amount of hype, such as choosing Wednesday the 24th to drop Mistral Large 2, which they are calling Large Enough.

Llama 3.1’s write-up does not include GPT-4-Mini, but Mistral works fast and is already incorporating the digs at Llama 3.1.

There are definitely big weaknesses here, but for some purposes it might offer good value. Too soon to tell.

The model is available ‘for research purposes only’ on Hugging Face.

They cover safety in 5.4.

Llama-3-405B is open weights, and the base model is available to boot.

If someone actively wants to get around Meta’s safety protocols, they will.

(There is also the cheap, quick and dirty alternative, which is to skip all that and jailbreak on day one. Which of course Pliny the Prompter did once again, noting that it was ‘a piece of cake.’)

There are two practical forms of safety that are available here.

1. If someone wants Llama-3 to remain safe and serves it up within a particular context, including Meta’s direct offering of the standard chat UI, you can implement the standard mundane safety protocols if you’d like.

2. A model is only as unsafe as its most unsafe underlying capabilities. This is a 4-level model, and 4-level models are essentially safe no matter what.

If you are doing a safety test on Llama-3 for things like ‘uplift’ of dangerous technologies, you need to essentially give your testers access to the version without any safety protocols. Because that’s the version they will have when it counts.

Ideally, you would also offer the opportunity to add scaffolding and fine tuning in various forms to strengthen the model, rather than only testing it in static form on its own. Again, you must test the thing you are irreversibly causing to exist in the future, not the thing people can use right now in a given room. So again, not the right test.

Thus, when their test found ‘insignificant uplift’ for cyberattacks or chemical or biological weapons, I only count that if they got a deliberately made unsafe version of Llama 3, and even then only partially. Without even that, we learn little.

To be clear, my expectation is that there is not substantial danger here, but I worry the tests would not have caught the danger if there was indeed danger.

One can also ask similar questions about the red teaming. If the red teams were indeed confined to using prompts that is not a great test of real world conditions.

If you are doing a safety test for a developer trying to incorporate the model into their product without bad publicity, that is different. Then you are on equal footing with closed models.

Thus, their offer of a prompt guard and Llama guard are reported as helpful, and this is nice if people actively want to stay safe, and not so nice if they do not. You cannot force people to use it.

In terms of that second type of safety, they offer their results in 5.4.4, but I found it impossible to understand what the numbers meant, and they did not offer comparisons I could parse to non-Llama models. I am choosing not to worry about it, as the lived experience will tell the tale, and many will modify the training anyway.

The more serious tests start in 5.4.5.

They find that Llama-3 has some issues with executing malicious code, which 405B does 10.4% of the time in code interpreter, versus 3.8% for the 70B model, ‘under certain prompts.’ And they find prompt injections worked 21.7% of the time.

These charts are hard to read, but Llama-3 405B seems to be doing okay, note that Claude was not tested here. Also of course this is comparing Llama-3 in its ‘safety enabled mode’ as it were.

They find Llama-3 does not have ‘significant susceptibilities in generating malicious code or exploiting vulnerabilities.’

Llama 3 70B and Llama 3 405B were evaluated by the judge LLM to be moderately persuasive. Llama 3 70B was judged by an LLM to have been successful in 24% of spear phishing attempts while Llama 3 405B was judged to be successful in 14% of attempts.

Okay, so that’s weird, right? Why is Llama 3 70B a lot more persuasive here than 405B? Perhaps because 70B was the judge? According to Llama, these success rates are typical for spearfishing attempts, which is itself a sad commentary on everyone. Claude thinks this was typical of ‘well-crafted’ attempts.

In practice, my beliefs about safety regarding Llama-3-405B are:

1. It is for all practical purposes 99%+ to be safe enough. I am not worried.

2. I do not however think their tests demonstrated this.

3. Instead, I base my opinion on our other knowledge of 4-level models.

4. If they continue to open weights future increasingly capable frontier models, at some point one of them will be actively unsafe from a catastrophic or existential risk perspective. When that happens, there is a very good chance that tests like this will not identify that risk, and once released the model cannot be taken back.

5. Or: I see no strong causal link here between having good reason to think the model is safe, and the choice of Meta to release its weights. And I see every reason to think they intend to keep releasing until stopped from doing so.

6. I do think that releasing this model now is directly net good for the world, in the sense that it is good for mundane utility without posing unacceptable risks, if you discount or do not highly value America’s relative position in AI or otherwise worry about national security implications. I do think there are reasonable national security arguments against it, and that the arguments that this path is actively good for America’s competition against China are essentially gaslighting. But I don’t think the impact is (yet) that big or that this is any kind of crisis.

7. Thus I am fine with this release. I do not predict any major unsafe results.

8. However I am worried about where this path leads in the future.

9. It would be unsurprising to see this used to accelerate various mundane harms, but I do not think this will happen in a way that should have stopped release.

Jeffrey Ladish: Is releasing 405B net good for the world? Our research at @PalisadeAI shows Llama 3 70B’s safety fine-tuning can be stripped in minutes for $0.50. We’ll see how much 405B costs, but it won’t be much. Releasing the weights of this model is a decision that can never be undone.

Ideolysis: I think it’s fine to undo 405b’s safety finetuning. what would be wrong with that?

Jeffrey Ladish: Idk we’ll see 🙃

Ideolysis: If we can agree on terms, I’d be willing to bet on this. something about how harmful to society the worst use of llama 3 (or any llm) is that we can find before a resolution date.

Given the power law distribution of harms and the question being our confidence level, Jeffrey should get odds here. I do think it would be useful to see what the market price would be.

Joshua Saxe (Meta, responding to Jeffrey): Totally respect your concerns. We showed our work around our security assessment of the model by open sourcing security capabilities evals and by publishing a white paper on our work simultaneous with the launch yesterday, described here.

With today’s launch of Llama 3.1, we release CyberSecEval 3, a wide-ranging evaluation framework for LLM security used in the development of the models. Additionally, we introduce and improve three LLM security guardrails.

[GitHub, Paper]

Sophia: there still haven’t been any meaningful negative consequences from open sourcing models, right?

Jeffrey Ladish: Most attacks in the wild that used models have used GPT-4, as far as I’ve seen. I think this makes sense, and is consistent with what we’ve found in our testing. You almost always want to use a better model. Though if refusals are high enough, you might go with a slightly weaker model… so you might prefer GPT-4o or Claude 3.5 sonnet for some kinds of tasks, because it’s annoying to have to deal with all the refusals of GPT-4o

Now with Llama 3 405B approaching GPT-4’s capabilities, being readily fine-tunable for anything, I think it might be the first time attackers would prefer an open weight model over one behind an API. Though with GPT-4o fine-tuning launching at about the same time, maybe they’ll go with that instead. However, OpenAI can shut down obvious evil fine-tunes of GPT-4o, and Meta cannot do the same with Llama. Imo that’s the biggest difference right now.

Again, I see these as acceptable costs and risks for this model. Indeed, if there is risk here, then it would be good in the long run to find that out while the damage it would cause is still not so bad.

Zuckerberg makes the incredulous claim, both in his interview with Cheung and in his manifesto, that it is impossible to keep models from being stolen by China and the CCP. That any secrets we have cannot be protected in the medium term.

His response is to propose the least security possible, giving models away freely. Under his thinking, if you are going to fully pay the costs, you might as well get the benefits, since the brief delay he expects before everything is stolen wouldn’t matter.

It is an excellent point that right now our security at those labs is woefully inadequate.

Leopold Aschenbrenner would add that even if you intended to make your models open weights, you would still need to protect the algorithmic insights within the labs.

Even Meta is not an open source AI company. Meta is an open weights AI company. They are (wisely) keeping plenty of internal details to themselves. And trying to protect those secrets as best they can.

It is Obvious Nonsense that it is impossible to ever protect secrets.

Josh You: Mark Zuckerberg argues that it doesn’t matter that China has access to open weights, because they will just steal weights anyway if they’re closed. Pretty remarkable.

Arthur Breitman: The CCP has not managed to steal or copy several key military tech. I have no doubt the CCP can produce a model like Llama 3.1, there’s never been _enough_ secret sauce or complexity to begin with. But the argument that nothing can be kept secret is defeatist, silly, and wrong.

I’m thinking among other things about nuclear submarine propeller design.

Lennart Heim: I disagree with Zuck’s perspective on releasing model weights. While I think releasing LLama 405B is beneficial, I don’t agree with this part. There’s a significant difference between theft and public release. Also, the challenges in securing these assets are not unattainable.

Firstly, theft vs. release: Stolen technology is hidden to be exploited secretly and to keep a backdoor open. In contrast, a public release distributes knowledge globally—these are fundamentally different actions. And what about threat actors other than states?

Secondly, defending model weights isn’t impossible. It’s actually easier than securing code or algorithmic insights. Model weights are hundreds of gigabytes; therefore, theft can be more easily prevented and detected.

Not saying it’s an easy feat but we shouldn’t give up on security so easily; the goal is to raise the barrier for attackers. My colleagues got a great report on securing AI model weights.

Also note that Zuckerberg thinks our ‘geopolitical adversaries’ would successfully steal the models, but then that is where it would end, the secrets would then be kept, including from our friends and allies. Curious.

Zuckerberg’s defeatism here is total.

The question is, are model weights a case where you cannot both deploy and properly use them and also simultaneously protect them? What would be the practical costs involved for how much security? Obviously there will be some cost in efficiency to implement effective security.

The other question is, are we in practice capable of implementing the necessary protocols? If our civilization is unable or unwilling to impose such restrictions on labs that would not choose to do this on their own, then we have a big problem.

Another question has to be asked. If it is impossible to ever protect secrets, or in practice we will choose not to do so, then that would mean that anything we create will also fall into the wrong hands, at minimum be used by our enemies, and likely be unleashed without restriction on the internet and for every malicious purpose. If you truly believed that, you would want to lay the groundwork to stop dangerous AIs before they were created, in case AIs did become too dangerous. Otherwise, once they were created, by your own claims it would be too late. Instead, Zuckerberg and others are willing to simply bet the planet and all of humanity on the resulting natural equilibrium being good. Why would that be?

It’s a very different approach than going on Dwarkesh, instead he goes to the friendly territory of Rowan Cheung, who is always gung ho about everything.

He announces Llama 3.1 405B, 70B and 8B, advocates for open models, complains about Apple and reiterates his prediction of a world of billions of AI agents except they are all mere tools with nothing to worry about.

1. He is high on his new models, saying that they are state of the art and competitive with closed source alternatives.

2. Llama 3.1 70B and 8B are distillations of 405B.

3. Zuckerberg says he expected AI to go like Linux and become open source. Now he thinks this is the inflection point, it will happen Real Soon Now, that open source will ‘become the standard’ and Llama to be the standard too. He is still predicting that the future plays out like Linux in his manifesto. Hype!

   1. Big Talk. I give him credit for admitting that he made this prediction before and was wrong then (reminder to: every economist who predicted 9 out of the last 4 recessions). I strongly predict he is once again wrong now.

   2. Big Talk continues later, claiming that there is no longer a big gap between open source and closed source. Acting like this is obviously permanent.

   3. Big Talk gets bigger when he claims Llama 4 is going to be the best, like no one ever was, and his general predictions of future dominance. Hype! He then backs off a bit and says it’s too early to know beyond ‘big leap.’

   4. Expects multimodal within a few months ‘outside of the EU.’

   5. Also in the EU, no matter his intention, that’s how open source works, sir. You can’t write ‘not for use in the EU’ and expect it not to get used there.

   6. Similarly, here Jared Friedman says Meta’s strategy on open weights began ‘with the accidental leak of the weights as a torrent on 4chan.’ And they like to tell versions of that story, but it is Obvious Nonsense. The ‘leak’ was not an ‘accident,’ it was the 100% inevitable result of their release strategy. Who was under the illusion that there would not obviously and quickly be such a ‘leak’?

4. His exciting use case is fine tuning and perhaps distilling one’s own model.

   1. On the one hand, yes, that is the point of a frontier open model.

   2. On the other hand, the art must have an end other than itself. It is always worrisome when the main exciting use of X is to make more Xs.

   3. Zuckerberg making a strong case here that he is helping China catch up.

5. Reiterates that Meta developed Llama out of fear of depending on someone else, and that they anticipate (want to cause) an ecosystem around Llama in particular.

   1. There are multiple implicit claims here not that Open Weights in general will catch up with Closed Weights.

   2. Rather, there is the claim that there will be One True Open Source Frontier Model, and essentially One True Model period, and that will be Llama, and everyone else will simply fine-tune and distill it as needed.

6. They are building partnerships to help people use Llama, including distillation and fine tuning. Drops a bunch of names.

7. Says people will want to own their models and that’s a big value proposition, and clearly thinks a derivative of Llama will be good enough for that.

8. Gives standard pro-open arguments, essentially quoting from his manifesto, comments there apply.

   1. His statements do not actually make any sense. Again, see comments below.

   2. Partial exception: His argument that we need to lock down the labs is correct, except his reaction to ‘the labs are not secure’ is to give up, and accept that China will simply steal everything anyway so give it away for free.

9. AI is technology with most potential to accelerate economy and enable everyone and do all the amazing things. And what helps with that? Same as everything else, you guessed it, open source. Explicitly says this will give other countries counterfactual access to frontier models matching ours to work with, erasing our advantage.

   1. Except that his vision of the future does not include anything fully transformational, positively or negatively, despite his prediction of billions of personalized AI agents. Only the good exactly transformational enough not to terrify you stuff. Why?

   2. I mean, you can guess. It is quite convenient a place to land.

10. Over four minutes on Apple. He is very mad that he wanted to ship things that were good for Meta, that he says would be good for customers, and Apple told him no.

    1. According to Claude, what did Apple stop? Cross-app tracking, in-app payments without Apple getting a cut, an alternative to an Apple store, making Messenger the default messaging app, doing things in the background that apps aren’t allowed to do, launching an in-app game platform within messenger, Web app versions of their products on iOS that would get around similar restrictions.

    2. According to Llama-405B, what did Apple stop? Cross-platform messaging, augmented reality, game streaming (being able to use a set of games without Apple approving them), digital payments and data tracking. Claude agrees that these were oversights. Digital payments was Libra.

    3. In other words, all of these features were attempts by Meta to get around Apple’s closed ecosystem and do whatever they want, or evade Apple’s requirement that it get a cut of payments (including via crypto), or collect data that Apple explicitly protects as a service to customers.

    4. They were all direct attempts to evade the rules of the system, get data they weren’t supposed to have, evade Apple’s taxes, or to take over relationships and services from Apple. To which Apple said no. So yeah.

    5. That’s because Apple owns the customer relationship exactly on the basis of providing a tightly controlled ecosystem. Users could instead choose Android, an open source OS, as I have, and largely they don’t want that. When they do choose Android, they mostly treat it as if it was closed, even when open.

    6. The rules against AR do seem sad, but that sells Meta more headsets, no?

    7. He then calls all this ‘restrictions on creativity.’

11. He says Windows is the ‘more open ecosystem’ compared to Apple in PCs, another standard argument, and that’s the better comparison than to Linux or Unix there, and open sometimes wins. Yes, in terms of it not being coupled to hardware, and yes open can sometimes win. Again he doesn’t seem to think AI is anything but the latest software fight, one he intends to ‘win’ the same as AR/VR.

12. Long term vision for products is lots of different AIs and AI services, not ‘one singular AI,’ as previously noted. Meta AI is ‘doing quite well’ and he thinks they are on track to be most used by end of year, likely a few months early. Give everyone the ability to create ‘their own AI agents.’ AI agents for everyone, everywhere, all the time, he equates it to email.

    1. I haven’t heard any stats on how much people are using Meta AI. It is plausible that shoving it onto every Facebook and Instagram user makes it bigger than ChatGPT on users. Claude is still the best product as per early reports, but their ads aside no one knows about it and it likely stays tiny.

13. He also wants to present as pro-creator by helping them engage with communities via ‘pulling in all their info from social media’ and reflecting their values.

    1. I think he needs to talk to more creatives and fans, and that this is pretty out of touch unless at minimum he can make a vastly better product than I expect anyone to offer soon.

14. He thinks the agents and social media communicators are ‘businesses’ for them, despite giving away the model for free. He will ‘build the best products’ rather than selling model access. So in a way this is far ‘more closed’ in practice rather than more open, as they will push their readymade solutions onto people and charge them? Otherwise how are they making money? How will they hold off competition after giving the base model away, what will be the secret sauce?

    1. Presumably the secret sauce will be claiming ownership of your social media, your data and your relationships, and trying to monetize that against you? I’m not sure how they expect that to work.

15. How does Zuckerberg think about various forms of anti-AI sentiment? He notes the internet bubble, and that AI might need time to mature as a business. Hard to tell when the product is ready to be a good business, and people will likely lose money for quite a while. On the consequences for people’s livelihoods, guess what he leans on? That’s right, open source, that’s how you ‘lift all boats.’ I do not understand this at all.

    1. The issues regular people worry about with AI is about it taking their jobs, why do they care if the AI that replaces them is open? If the AI that enshittifies the internet is open?

    2. What is the ‘closed ecosystem’ going to do to them? There’s clearly already a race to the bottom on price and speed, and if Zuckerberg is right all he’s going to do is bring even more cheaper, faster, smarter, more customized AIs more places faster. Which he’d think was cool, and has its huge advantages to be sure, but the people worried about AI’s mundane downsides are not going to like that for quite obvious reasons even if it all basically works out great.

    3. And of course he does not even mention, in talking about people’s worries about AI and anti-AI sentiment, any worries that something might actually go seriously wrong on any level. He likes to pretend that’s a Can’t Happen.

16. Sharp contrast overall to his previous statements. Previously he sounded like a (relative) voice of reason, saying you open up some models where the model is not the product and it is safe to do so, but perhaps not others. I could understand that perspective, as I agree that currently the releases are in practice fine, including this one, on their own.

17. Now instead he’s sounding like a True Believer on a mission, similar to Yann LeCun, and it’s the principle of the thing. Open source is now the answer to everything, good for everything, all the time, no matter what. Full meme. Not good.

    1. One can contrast this with the reaction for example of Andrew Critch, who emphasizes the importance of openness and was eagerly awaiting and praises this release, while warning that we are approaching the day when such a release of a frontier model would be irresponsible and dangerous.

18. I worry that this is essentially ego driven at this point, that Zuckerberg has failed to keep his identity small and all the people yelling about open models on Twitter and all the advocacy within and from Meta has overridden his ability to consider the practical questions.

19. On the flip side, the hope is that this is Hype, Big Talk, Cheap Talk. Once he decides to open release 405B, he has little incentive to not present as the unwavering undoubting advocate, until he holds something back later, if he ever does choose to do that, which he might not. Could be no different than his or Musk’s ‘we will have greatest model Real Soon Now’ claims.

20. Consider the parallel to his Metaverse commitments, perhaps. Or his commitments to the original Facebook, which worked out.

Marc Zuckerberg offers his thesis that Open Source AI is the Path Forward.

Ultimately this is a rehash of the same old arguments.

He has said it all before, as have many others. Yet there is so much he ignores, because it does not help his case.

I found this commentary on it enlightening:

Andrej Karpathy: The philosophy underlying this release is in this longread from Zuck, well worth reading as it nicely covers all the major points and arguments in favor of the open AI ecosystem worldview.

So I suppose this response is a rehash of the same old responses.

Most important is what this ‘covering of all major points and arguments’ doesn’t cover.

1. Zuckerberg does not even mention existential or catastrophic risk even to deny that they are concerns. He does not address any of the standard catastrophic harms in any other capacity either, or explain how this protects against them.

2. He does not address potential loss of control. He does not address competitive dynamics and pressures that might induce loss of control in various ways.

3. He does not deal with any issues surrounding if AI became no longer a ‘mere tool’ used by humans (my term not his), it is clear (from elsewhere) that he thinks or at least reliably claims this won’t ever happen, perhaps because of reasons. This despite his prediction elsewhere of billions of AI agents running around. The open weights arguments seem to consistently assume implicitly that this is a Can’t Happen or not worth considering.

4. He does not address externalities of safety and user desire to be actively unsafe (or not make sacrifices for the safety of others) in AI versus the relative lack of this issue in other open source software such as Linux, where incentives mostly align.

5. Indeed he treats this as an identical situation to Linux in almost every way. You would mostly have no idea, reading these arguments, that the subject is even AI.

6. He does not address constraining of potential future actions and inability to reverse mistakes, or even to stop pushing forward as fast as possible towards whatever individuals most want to run or what is best at causing itself to get copied. He does not address the difficulties this raises for governments or even international cooperation if they need to act, or perhaps he thinks that is good. He does not address the impact on potential racing dynamics.

7. He does not address the financial incentives of other firms, only Meta, which he simultaneously thinks can freely give away Llama because others will have similarly strong options already, and needs to develop Llama at great cost to avoid being stuck in someone else’s ecosystem. Which is it?

8. He states that in order to maintain a lead against an adversary, you must continuously give away what you have for free. The argument is that national security and competitiveness is helped because ‘our advantage is openness.’

9. He is completely the meme that the solution to everything is always Open Source, no matter what, all the time. In his thesis it helps along every axis, solves every problem, and is going to win anyway, and so on. This is not an attempt to inform or seek truth, this is arguments as soldiers to advocate for what he wants. Period.

10. In short he does not address any of the primary actual objections or concerns.

You can very safely skip both the letter and the rest of my response.

To the extent that I considered deleting the non-summary response below, but hey.

Still here? All right, let’s play it again, Sam.

His safety argument is based on dividing harms into intentional versus unintentional. This is a useful distinction in many circumstances, and in some sense axiomatically true, but he then uses this to assume that any given thing must either be a bad actor, or be due to some sort of active mistake. As I’ve tried to explain many times, that does not cover the space, an unintentional harm can result from everyone following their individual incentives.

Linux gets safer with many eyes because what is safe for the user is safe for others, so the incentives align, and if something goes wrong for you that mostly blows up you in particular, and there is ample opportunity to fix the error after it happens and try again. Neither of these will be true in the context of future more capable AI.

His argument for why open weights are safer for unintentional harm is that the system are more transparent and can be widely scrutinized. Again, that only works if everyone who runs the system actively wants their system to be safe in that same sense. Otherwise, whoops. Overall it is an advantage, but he treats it as the only consideration.

You could call failing to treat safety of your AI the way Linux treats its safety ‘intentional’ harm if you would like, I suppose, in which case intentional harm includes intentionally taking risk, or trading off risk to get reward, but obviously everyone including Meta and every corporation and government will be forced to (and choose to) do some amount of that.

For unintentional harm, he draws distinction between ‘individual or small scale’ actors versions large actors.

For small actors, he goes straight to the ‘good guy with an AI will stop the bad guy with an AI’ rhetoric, in different words. The entire frame is that AI will remain a tool, and the assumption is that wider distribution of identical tools to all players will favor defense over offense, without any argument for why we should presume that.

Zuckerberg says that widely deploying tools at scale is how Meta protects its social networks. That is true, but the reason Meta is able to (somewhat) protect its social networks is that it brings a massive advantage to the table. It is in context the ‘good guy with the tool’ and has better tools than the bad guys with their tools. Ensuring that you can never win that arms race does not seem like a good idea, even in this narrow context.

Why would you ensure your opponents are armed, other than a deeply strange sense of honor? Why would you assume that access to more inference compute will be decisive in such conflicts? Or that not having superior models to work with is actively helpful, as he suggests? I do not see why, and he does not say.

He certainly does not argue why this should allow us to secure ourselves against other forms of malicious use, that do not involve a clear defending agent the way Meta defends its social network. He does not explain how this would defend against the typical catastrophic threats, even if AI remains a tool. There’s only assertion here. He says that with new harms ‘the balance of power would be crucial’ but then uses this to… advocate for giving up a key advantage in the balance of power between the defenders and these potential bad actors. How does that help?

If AI in the hands of such a small actor becomes more than a ‘mere tool’ of course than all of this is out the window.

And in particular, if the threat model is that competition between AIs, and competition between humans with their AIs that they feel constant pressure to give authority to while removing humans from loops, and to turn into increasingly independent and strategic agents? Then open models take away all our options to provide any checks on these competitive dynamics, short of monitoring of every computer everywhere. Such questions are simply not addressed.

If it turns out a mistake has been made, it could easily be too late. Once you release such an open model you cannot take it back, again short of a true dystopian scenario.

Then he asks about ‘states with massive resources.’ Again notice the bifurcation trick, dealing only with one extreme or the other, but yes these are important cases. He says, our advantage is openness, so we must be open and release all our progress to avoid giving China the advantage. You see, China is great at espionage, so they would simply steal our models anyway.

(Which is an excellent point! We should totally be locking down the labs to stop this.)

Zuckerberg also posits another false binary choice:

1. A ‘world of open models.’

2. A ‘world of no open models.’

While there are those like Zukerberg that propose that open models be at the frontier and the standard, this ‘world of no open models’ is a fever dream. There are some who take extreme positions, but the central argument is whether there should be some upper bound on how capable open models can be at a given time, or whether open models should be required to abide by ordinary safety regulations.

The argument is not that there should be no open models at all. That is not my position. I have zero problem with his release of the Llama 3.1 70B model. And if I felt that things would stop here, I would not be especially concerned about Llama 3.1 405B either (although for that there are others who feel more strongly, and there are national security concerns), it is the principle and precedent for the future that is being debated here.

Even more than that, the argument that not giving away our best models and entire ecosystem of innovations increases the probability that we will not be in the lead? This is Obvious Nonsense. I notice I am deeply confused.

Linux is a great thing. We do not maintain Linux with the goal of giving America and its allies the lead in operating systems. It will obviously do nothing of the kind. That. Makes. Zero. Sense.

He says most of today’s tech companies are built on open source software. So we should give that software to China so they can build their own companies? To their government as well? Or else we risk losing our lead? What? Seriously, what?

Yet somehow they keep repeating that line.

If everyone affirms this is indeed all the major arguments for open weights, then I can at some point soon produce a polished full version as a post and refer back to it, and consider the matter closed until someone comes up with new arguments.

Zack Witten: Crazy stat from the Llama paper:

> For Llama 3 405B , we noted a diurnal 1-2% throughput variation based on time-of-day… the result of higher mid-day temperatures impacting GPU dynamic voltage and frequency scaling.

2025 jobs be like “Applied Metereologist, Pretraining”

It was all quiet. Then it wasn’t.

Note the timestamps on both of these.

Dwarkesh Patel did a podcast with Mark Zuckerberg on the 18th. It was timed to coincide with the release of much of Llama-3, very much the approach of telling your story directly. Dwarkesh is now the true tech media. A meteoric rise, and well earned.

This is two related posts in one. First I cover the podcast, then I cover Llama-3 itself.

My notes are edited to incorporate context from later explorations of Llama-3, as I judged that the readability benefits exceeded the purity costs.

1. (1: 00) They start with Llama 3 and the new L3-powered version of Meta AI. Zuckerberg says “With Llama 3, we think now that Meta AI is the most intelligent, freely-available assistant that people can use.” If this means ‘free as in speech’ then the statement is clearly false. So I presume he means ‘free as in beer.’

2. Is that claim true? Is Meta AI now smarter than GPT-3.5, Claude 2 and Gemini Pro 1.0? As I write this it is too soon to tell. Gemini Pro 1.0 and Claude 3 Sonnet are slightly ahead of Llama-3 70B on the Arena leaderboard. But it is close. The statement seems like a claim one can make within ‘reasonable hype.’ Also, Meta integrates Google and Bing for real-time knowledge, so the question there is if that process is any good, since most browser use by LLMs is not good.

3. (1: 30) Meta are going in big on their UIs, top of Facebook, Instagram and Messenger. That makes sense if they have a good product that is robust, and safe in the mundane sense. If it is not, this is going to be at the top of chat lists for teenagers automatically, so whoo boy. Even if it is safe, there are enough people who really do not like AI that this is probably a whoo boy anyway. Popcorn time.

4. (1: 45) They will have the ability to animate images and it generates high quality images as you are typing and updates them in real time as you are typing details. I can confirm this feature is cool. He promises multimodality, more ‘multi-linguality’ and bigger context windows.

5. (3: 00) Now the technical stuff. Llama-3 follows tradition in training models in three sizes, here 8b, 70b that released on 4/18, and a 405b that is still training. He says 405b is already around 85 MMLU and they expect leading benchmarks. The 8b Llama-3 is almost as good as the 70b Llama-2.

6. (5: 15) What went wrong earlier for Meta and how did they fix it? He highlights Reels, with its push to recommend ‘unconnected content,’ meaning things you did not ask for, and not having enough compute for that. They were behind. So they ordered double the GPUs that needed. They didn’t realize the type of model they would want to train.

7. (7: 30) Back in 2006, what would Zuck have sold for when he turned down $1 billion? He says he realized if he sold he’d just build another similar company, so why sell? It wasn’t about the number, he wasn’t in position to evaluate the number. And I think that is actually wise there. You can realize that you do not want to accept any offer someone would actually make.

8. (9: 15) When did making AGI become a key priority? Zuck points out Facebook AI Research (FAIR) is 10 years old as a research group. Over that time it has become clear you need AGI, he says, to support all their other products. He notes that training models on coding generalizes and helps their performance elsewhere, and that was a top focus for Llama-3.

9. So Meta needs to solve AGI because if they don’t ‘their products will be lame.’ It seems increasingly likely, as we will see in several ways, that Zuck does not actually believe in ‘real’ AGI. By ‘AGI’ he means somewhat more capable AI.

10. (13: 40) What will the Llama that makes cool products be able to do? Replace the engineers at Meta? Zuck tries to dodge, says we’re not ‘replacing’ people as much as making them more productive, hopefully 10x or more, says there is no one threshold for human intelligence, AGI isn’t one thing. He is focused on different modalities, especially 3D and emotional understanding, in addition to the usual things like memory and reasoning.

11. (16: 00) What will we use all our data for? Zuck says AI will be in everything, and there will be a Meta general assistant product that does complicated tasks. He wants to let creators own an AI and train it how they want to ‘engage their community.’ But then he admits these are only consumer use cases and it will change everything in the economy.

12. (18: 25) When do we get the good agents? Zuck says we do not know. It depends on the scaffolding. He wants to progressively move more of that into the model to make them better agents on their own so this stops being ‘brittle and non-general.’ It has much better tool use, you do not need to hand code. This Is Fine.

13. (22: 20) What community fine tune is most personally exciting? Zuck says he doesn’t know, it surprises you, if he knew he’d build it himself.

    1. This doesn’t match my model of this, where you want to specialize, some things are left to others, which seems doubly true here with open model weights. He mentions that 8b is too big for many use cases, we should try to build a 1b or smaller model too.

    2. Also he mentions that they do a ton of inference because they have a ton of customers, so that dominates their compute usage over time. It makes sense for them to do what for others would be overtraining, also training more seemed to keep paying dividends for a long time.

    3. I would presume the other big labs will be in similar positions going forward.

14. (26: 00) How much better will Llama-4 get? How will models improve? Zuck says (correctly) this is one of the great questions, on one knows, how long does an exponential curve keep going? He says probably long enough that the infrastructure is worth investing in, and a lot of companies are investing a lot.

15. (28: 00) He thinks energy constraints will soon bind, not chips. No one has built a gigawatt single training cluster yet. And that is slower because energy gets permitted at the speed of government and then has to be physically built. One does not simply get a bunch of energy, compute and data together.

16. If concentrations of energy generation are the true bottleneck, then anyone who says ‘government has no means to control this’ or ‘government cannot control this without being totalitarian’ would be very wrong, this is a very easy thing to spot, isolate and supervise. Indeed, we almost ‘get it for free’ given we are already massively over restricting energy generation and oversee industrial consumption.

17. (30: 00) What would Meta do with 10x more money? More energy, which would allow bigger clusters, but true bottleneck is time. Right now data center energy tops out at something like 50mw-150mw. But 300mw-1gw, that’s new, that’s a meaningful nuclear power plant. It will happen but not next year. Dwarkesh mentions Amazon’s 950mw facility, Zuck says he is unsure about that.

18. (31: 40) What about distributed computing? Zuck says it is unknown how much of that is feasible, and suggests that a lot of training in future might be inference to generate synthetic data.

19. (32: 25) If that’s what this is about, could this work for Llama-3? Could you use these models to get data for these models to get smarter? De facto one might say ‘RSI Real Soon Now (RSI RSN)?’ Zuck says ‘there are going to be dynamics like that’ but there are natural limits on model architecture. He points out there is nothing like Llama-3 400B currently in open source, that will change things a lot, but says it can only go so far. That all makes sense, at some point you have to restart the architecture, but that does not fully rule out the scenario.

20. (34: 15) Big picture, what’s up with AI for the next decade? How big a deal is it? Zuck says pretty fundamental, like the creation of computing, going from not having computers to having computers. You’ll get ‘all these new apps’ and it will ‘let people do what they want a lot more.’

    1. He notices it is very hard to reason about how this goes.

    2. He strongly expects physical constraints to prevent fast takeoff, or even ‘slow takeoff,’ expecting it to be decades to fully get there.

    3. Notice again his expectations here are very much within the mundane range.

21. That could be the central crux here. If he thinks that nothing we build can get around the physical constraints for decades, then that has a lot of implications.

22. (36: 00) Dwarkesh says, but what about on that cosmic, longer-term scale? What will the universe look like? Will AI be like humans evolving or harnessing fire? Zuck says that is tricky. He says that people have come to grips throughout history with noticing that humanity is not unique in various ways but is still super special. He notices that intelligence is not clearly fundamentally connected to life, it is distinct from consciousness and agency. Which he says makes it a super valuable tool.

    1. Once again, even in this scenario, there’s that word again. Tool.

23. A key problem with this is agency is super useful. There is a reason Meta’s central plan is to create an active AI assistant for you that will act are your personal agent. Why Meta is striving to bring as much agency capability directly into the models, and also building more agency capability on top of that. The first thing people are doing and will do, in many contexts, is strive to give the AI as much agency as possible. So even if that doesn’t happen ‘on its own’ it happens anyway. My expectation is that if you wanted to create a non-agent, you can probably do that, but you and everyone else with sufficient access to the model have to choose to do that.

24. (38: 00) Zuck: “Which is why I don’t think anyone should be dogmatic about how they plan to develop it or what they plan to do. You want to look at it with each release. We’re obviously very pro open source, but I haven’t committed to releasing every single thing that we do. I’m basically very inclined to think that open sourcing is going to be good for the community and also good for us because we’ll benefit from the innovations. If at some point however there is some qualitative change in what the thing is capable of, and we feel like it’s capable of, and we feel it is not responsible to open source it, then we won’t. It’s all very difficult to predict.”

25. Bravo. Previously we have seen him say they were going to open source AGI. He might intend to do that anyway. This continues Zuck trying to have it both ways. He says both ‘we will open source everything up to and including AGI’ and also ‘we might not’ at different times.

    1. The reconciliation is simple. When Zuck says ‘AGI’ he does not mean AGI.

26. This suggests an obvious compromise. We can all negotiate on what capabilities would constitute something too dangerous, and draw a line there, with the line drawn in anticipation of what can be built on top of the model that is being considered for release, and understanding that all safety work will rapidly be undone and so on.

    1. We are talking price, and perhaps are not even that far apart.

    2. I am totally fine with Llama-3 70B being released.

    3. I do notice that open sourcing Llama-3 405B sounds like a national security concern, and as I discuss later if I was in NatSec I would be asking how I could prevent Meta from releasing the weights for national competitiveness reasons (to not supercharge Chinese AI) with a side of catastrophic misuse by non-state actors.

    4. But I do not expect existential risk from Llama-3.

27. (38: 45) So Dwarkesh asks exactly that. What would it take to give Zuck pause on open sourcing the results of a future model?

    1. Zuck says it is hard to measure that in the abstract. He says if you can ‘mitigate the negative behaviors’ of a product, then those behaviors are okay.

    2. The whole point is that you can to some extent do mitigations while you control the model (this is still super hard and jailbreaks are universally possible at least for now) but if you open source then your mitigations get fully undone.

28. Thus I see this as another crux. What does ‘mitigate’ mean here? What is the proposal for how that would work? How is this not as fake as Stability.ai saying they are taking safety precautions with Stable Diffusion 3, the most generous interpretation of which I can imagine is ‘if someone does a fine tune and a new checkpoint and adds a LoRa then that is not our fault.’ Which is a distinction without a difference.

29. (40: 00) Zuck says it is hard to enumerate all the ways something can be good or bad in advance. Very true.

30. As an aside, the ads here are really cool, pitches for plausibly useful AI products. Dwarkesh’s readings are uninspired, but the actual content is actively positive.

31. (42: 30) Zuck: “Some people who have bad faith are going to try and strip out all the bad stuff. So I do think that’s an issue.”

    1. Isn’t it more accurate to say that people will for various reasons definitely strip out all the protections, as they have consistently always done, barring an unknown future innovation?

32. (42: 45) And here it is, as usual. Zuck: “I do think that a concentration of AI in the future has the potential to be as dangerous as it being widespread… people ask ‘is it bad for it to be out in the wild and just widely available?’ I think another version of this is that it’s probably also pretty bad for one institution to have an AI that is way more powerful than everyone else’s AI.” And so on.

33. Something odd happens with his answer here. Up until this point, Zuck has been saying a mix of interesting claims, some of which I agree with and some where I disagree. I think he is making some key conceptual mistakes, and of course is talking his book as one would expect, but it is a unique perspective and voice. Now, suddenly, we get the generic open source arguments I’ve heard time and again, like they were out of a tape recorder.

34. And then he says ‘I don’t hear people talking about this much.’ Well, actually, I hear people talking about it constantly. It is incessant, in a metaphorically very ‘isolated demand for rigor’ kind of way, to hear ‘the real danger is concentration of power’ or concentration of AI capability. Such people usually say this without justification, and without any indication they understand what the ‘not real’ danger is that they are dismissing as not real or why they claim that it is not real.

35. (45: 00) He says what keeps him up at night is that someone untrustworthy that has the super strong AI, that this is ‘potentially a much bigger risk.’ That a bad actor who got a hold of a strong AI might cause a lot of mayhem in a world where not everyone has a strong AI.

    1. This is a bigger concern than AI getting control of the future? Bigger than human extinction? Bigger than every actor, however bad, having such access?

    2. Presumably he means more likely, or some combination of likely and bigger.

36. So yes, his main concern is that the wrong monkey might get the poisoned banana and use it against other monkeys, it is only a tool after all. So instead we have to make sure all monkeys have such access?

37. (46: 00) It is overall a relatively good version of the generic open source case. He at least acknowledges that there are risks on all sides, and certainly I agree with that.

    1. I see no indication from the argument that he actually understands what the risks of open sourced highly capable models are, or that he has considered them and has a reason why they would not come to pass.

    2. His position here appears to be based on ‘this is a tool and will always be a tool’ and combining that with an implied presumption about offense-defense balance.

    3. I certainly have no idea what his plan (or expectation) is to deal with various competitive dynamics and incentives, or how he would keep the AIs from being something more than tools if they were capable of being more than that.

    4. The better version of this case more explicitly denies future AI capabilities.

38. I could write the standard reply in more detail than I have above, but I get tired. I should have a canonical link to use in these spots, but right now I do not.

39. (46: 30) Instead Dwarkesh says it seems plausible that we could get an open source AI to become the standard and the best model, and that would be fine, preferable even. But he asks, mechanically, how you stop a bad actor in that world.

    1. He first asks about bioweapons.

    2. Zuck answers that stronger AIs are good cybersecurity defense.

    3. Dwarkesh asks, what if bioweapons aren’t like that.

    4. Zuck agrees he doesn’t know that bioweapons do not work that way and it makes sense to worry there. He suggests not training certain knowledge into the model (which seems unlikely to me to be that big a barrier, because the world implies itself and also you can give it the missing data), but admits if you get a sufficiently bad actor (which you will), and you don’t have another AI that can understand and balance that (which seems hard under equality), then that ‘could be a risk.’

40. (48: 00) What if you for example caught a future Llama lying to you? Zuck says right now we see hallucinations and asks how you would tell the difference between that and deception, says there is a lot to think about, speaks of ‘long-term theoretical risks’ and asks to balance this with ‘real risks that we face today.’ His deception worry is ‘people using this to generate misinformation.’

41. (49: 15) He says that the way he has beaten misinformation so far is by building AI systems that are smarter than the adversarial ones.

    1. Exactly. Not ‘as smart.’ Smarter.

    2. Zuck is playing defense here. He has the harder job.

    3. If those trying to get ‘misinformation’ or other undesired content past Facebook’s (or Twitter’s or GMail’s) filters had the same level of sophistication and skill and resources as Meta and Google, you would have to whitelist in order to use Facebook, Twitter and GMail.

    4. The key question will be, how much of being smarter will be the base model?

42. (49: 45) Zuck says hate speech is not super adversarial in the sense that people are not getting better at being racist.

    1. I think in this sense that is wrong, and they totally are in both senses? Racists invent new dog whistles, new symbols, new metaphors, new deniable things. They look for what they can and cannot say in different places. They come up with new arguments. If you came with the 1970s racism today it would go very badly for you, let alone the 1870s or 1670s racism. And then he says that AIs here are getting more sophisticated faster than people.

    2. What is going to happen is that the racists are going to get their racist AI systems (see: Gab) and start using the AI to generate and select their racist arguments.

    3. If your AI needs to have high accuracy to both false positives and false negatives, then you need a capability advantage over the attack generation mechanism.

    4. This is all ‘without loss of generality.’ You can mostly substitute anything else you dislike for racism here if you change the dates or other details.

43. (50: 30) Zuck then contrasts this with nation states interfering in elections, where he says nation-states are ‘have cutting edge technology’ and are getting better every year. He says this is ‘not like someone trying to say mean things, they have a goal.’

    1. Well, saying mean things is also a goal, and I have seen people be very persistent and creative in saying mean things when they want to do that.

    2. Indeed, Mark Zuckerberg went to Ardsley High School and Phillips Exeter Academy, they made this movie The Social Network and also saying mean things about Mark Zuckerberg is a top internet passtime. I am going to take a wild guess that he experienced this first hand. A lot.

44. I would also more centrally say no, zero nation states have cutting edge election interference technology, except insofar as ‘whatever is available to the most capable foreign nation-state at this, maybe Russia’ is defined as the cutting edge. Plenty of domestic and non-state actors are ahead of the game here. And no state actor, or probably any domestic actor either, is going to have access to an optimized-for-propaganda-and-chaos version of Gemini, GPT-4 or Claude Opus. We are blessed here, and of course we should not pretend that past attempts were so sophisticated or impactful. Indeed, what may happen in the coming months is that, by releasing Llama-3 400B, Zuck instantly gives Russia, China, North Korea and everyone else exactly this ‘cutting edge technology’ with which to interfere.

45. I of course think the main deception problems with AI lie in the future, and have very little to do with traditional forms of ‘misinformation’ or ‘election interference.’ I do still find it useful to contrast our models of those issues.

46. (51: 30) He says ‘for the foreseeable future’ he is optimistic they will be able to open source. He doesn’t want to ‘take our eye off the ball’ of what people are trying to use the models for today. I would urge him to keep his eye on that ball, but also skate where the puck is going. Do not move directly towards the ball.

47. (54: 30) Fun time, what period of time to go back to? Zuck checks, it has to be the past. He talks about the metaverse.

48. (59: 00) Zuck is incapable of not taking a swing at building the next thing. He spends so much time finding out if he could, I suppose.

49. (1: 02: 00) Caesar Augustus seeking peace. Zuck suggests peace at the time was a new concept as anything other than a pause between wars. I notice I am skeptical. Then Zuck transitions from ‘wanting the economy to be not zero-sum’ to ‘a lot of investors don’t understand why we would open source this.’ And says ‘there are more reasonable things than people think’ and that open source creates winners. The framing attempt is noted.

    1. I instead think most investors understand perfectly well why Meta might open source here. It is not hard to figure this out. Indeed, the loudest advocates for open source AI are largely venture capitalists.

    2. That does not mean that open sourcing is a wise (or unwise) business move.

50. (1: 05: 00) Suppose there was a $10 billion model, it was totally safe even with fine tuning, would you open source? Zuck says ‘as long as it’s helping us, yeah.’

    1. Exactly. If it is good for business and it is not an irresponsible thing to do, it was actually ‘totally safe’ in the ways that matter, and you think it is good for the world too, then why not?

    2. My only caveat would be to ensure you are thinking well about what ‘safe’ means in that context, as it applies to the future path the world will take. One does not, in either direction, want to use a narrow view of ‘safe.’

51. (1: 06: 00) Zuck notes he does not open source Meta’s products. Software yes, products no. Something to keep in mind.

52. (1: 07: 00) Dwarkesh asks if training will be commodified? Zuck says maybe. Or it could go towards qualitative improvements via specialization.

53. (1: 08: 45) Zuck notes that several times, Meta has wanted to launch features, and Apple has said no.

    1. We don’t know which features he is referring to.

    2. We do know Apple and Meta have been fighting for a while about app tracking and privacy, and about commissions and informing users about the commissions, and perhaps messaging.

54. (1: 09: 00) He therefore asks, what if someone has an API and tells you what you can build? Meta needs to build the model themselves to ensure they are not in that position.

    1. I don’t love that these are the incentives, but if you are as big as Meta and want to do Meta things, then I am sympathetic to Meta in particular wanting to ensure it has ownership of the models it uses internally, even if that means large costs and even if it also meant being a bit behind by default.

55. The core dilemma that cannot be resolved is: Either there is someone, be it corporation, government or other entity, that is giving you an API or other UI that decides what you can and cannot do, or there is not. Either there is the ability to modify the model’s weights and use various other methods to get it to do whatever you want it to do, or there is not. The goals of ‘everyone is free to do what they want whenever they want’ and ‘there is some action we want to ensure people do not take’ are mutually exclusive.

56. You can and should seek compromise, to be on the production possibilities frontier, where you impose minimal restrictions to get the necessary guardrails in place where that is worthwhile, and otherwise let people do what they want. In some cases, that can even be zero guardrails and no restrictions. In other cases, such as physically building nuclear weapons, you want strict controls. But there is no taking a third option, you have to make the choice.

57. (1: 09: 45) I totally do buy Zuck’s central case here, that if you have software that is generally beneficial to builders, and you open source it, that has large benefits. So if there is no reason not to do that, and often there isn’t, you should do that.

58. (1: 10: 15) What about licensing the model instead, with a fee? Zuck says he would like that. He notes that the largest companies cannot freely use Llama under their license, so that if Amazon or Microsoft started selling Llama then Meta could get a revenue share.

59. (1: 12: 00) Dwarkesh presses on the question of red flags, pointing to the responsible scaling policy (RSP) of Anthropic and preparedness framework of OpenAI, saying he wishes there was a similar framework at Meta saying what concrete things should stop open sourcing or even deployment of future models.

60. Zuck says that is a fair point on the existential risk side, right now they are focusing on risks they see today, the content risk, avoiding helping people do violence or commit fraud. He says for at least one generation beyond this one and likely two, the harms that need more mitigation will remain the ‘more mundane harms’ like fraud, he doesn’t want to shortchange that, perhaps my term is catching on. Dwarkesh replies ‘Meta can handle both’ and Zuck says yep.

61. There is no contradiction here. Meta can (and should) put the majority of its risk mitigation efforts into mundane harms right now, and also should have a framework for when existential risks would become concerning enough to reconsider how to deploy (or later train) a model, and otherwise spend relatively less on the issue. And it is perfectly fine to expect not to hit those thresholds for several generations. The key is to lay out the plan.

62. (1: 13: 20) Has the impact of the open source tools Meta has released been bigger than the impact of its social media? Zuck says it is an interesting question, but half the world uses their social media. And yes, I think it is a fun question, but the answer is clearly no, the social media is more counterfactually important by far.

63. (1: 14: 45) Meta custom silicon coming soon? Not Llama-4, but soon after that. They already moved a bunch of Reels inference onto their own silicon, and use Nvidia chips only for training.

64. (1: 16: 00) Could Zuck have made Google+ work as CEO of Google+? Zuck says he doesn’t know, that’s tough. One problem was that Google+ didn’t have a CEO, it was only a division, and points to issues of focus. Keep the main thing the main thing.

That was a great interview. It tackled important questions. For most of it, Zuck seemed like a real person with a unique perspective, saying real things.

The exception was that weird period where he was defending open source principles using what sounded like someone else’s speech on a tape recorder. Whereas at other times, his thoughts on open source were also nuanced and thoughtful. Dwarkesh was unafraid to press him on questions of open source throughout the interview.

What Dwarkesh failed to get was any details from Zuck about existential or catastrophic risk. We are left without any idea of how Zuck thinks about those questions, or what he thinks would be signs that we are in such danger, or what we might do about it. He tried to do this with the idea of Meta needing a risk policy, but Zuck kept dodging. I think there was more room to press on specifics. Once again this presumably comes down to Zuck not believing the dangerous capabilities will exist.

Nor was there much discussion of the competitive dynamics that happen when everyone has access to the same unrestricted advanced AI models, and what might happen as a result.

I also think Zuck is failing to grapple with even the difficulties of mundane content moderation, an area where he is an expert, and I would like to see his explicit response. Previously, he has said that only a company with the resources of a Meta can do content moderation at this point.

I think he was wrong in the sense that small bespoke gardens are often successfully well-defended. But I think Zuck was right that if you want to defend something worth attacking, like Meta, you need scale and you need to have the expertise advantage. But if those he is defending against also have the resources of Meta where it counts, then what happens?

So if there is another interview, I hope there is more pressing on those types of questions.

In terms of how committed Zuck is to open source, the answer is a lot but not without limit. He will cross that bridge when he comes to it. On the horizon he sees no bridge, but that can quickly change. His core expectation is that we have a long way to go before AI goes beyond being a tool, even though he also thinks it will soon very much be everyone’s personal agent. And he especially thinks that energy restrictions will soon bind, which will stifle growth because that goes up against physical limitations and government regulations. It is an interesting theory. If it does happen, it has a lot of advantages.

Ate-a-Pi has a good reaction writeup on Twitter. It was most interesting in seeing different points of emphasis. The more I think about it, the more Ate-a-Pi nailed it pulling these parts out:

Ate-a-Pi (edited down): TLDR: AI winter is here. Zuck is a realist, and believes progress will be incremental from here on. No AGI for you in 2025.

1. Zuck is essentially an real world growth pessimist. He thinks the bottlenecks start appearing soon for energy and they will be take decades to resolve. AI growth will thus be gated on real world constraints.

2. Zuck would stop open sourcing if the model is the product.

3. Believes they will be able to move from Nvidia GPUs to custom silicon soon.

Overall, I was surprised by how negative the interview was.

A) Energy – Zuck is pessimistic about the real world growth necessary to support the increase in compute. Meanwhile the raw compute per unit energy has doubled every 2 years for the last decade. Jensen also is aware of this, and it beggars belief that he does not think of paths forward where he has to continue this ramp.

B) AGI Negative Zuck fundamentally

> does not believe the model, the AI itself, will be the product.

> It is the context, the network graph of friendships per user, the moderation, the memory, the infrastructure that is the product.

> Allows him to freely release open source models, because he has all of the rest of the pieces of user facing scaffolding already done.

> Does not believe in states of the world where a 100x improvement from GPT-4 are possible, or that AGI is possible within a short timeframe.

An actual AGI

> where the a small model learns and accompanies the user for long periods

> while maintaining its own state

> with a constitution of what it can or cannot do

> rather than frequent updates from a central server

> would be detrimental to Meta’s business,

> would cause a re-evaluation of what they are doing

Especially on point is that Zuck never expects the AI itself to be the product. This is a common pattern among advocates for open model weights – they do not actually believe in AGI or the future capabilities of the product. It is not obvious Zuck and I even disagree so much on what capabilities would make it unwise to open up model weights. Which is all the more reason to spell out what that threshold would be.

Then there is speculation from Ate-a-Pi that perhaps Zuck is being realistic because Meta does not need to raise capital, whereas others hype to raise capital. That surely matters on the margin, in both directions. Zuck would love if Altman and Amodei were less able to raise capital.

But also I am confident this is a real disagreement, to a large extent, on both sides. These people expecting big jumps from here might turn out to be bluffing. But I am confident they think their hand is good.

Daniel Jeffries highlights GPT-5 as key evidence either way, which seems right.

Daniel Jeffries: The litmus test about whether we hit a plateau with LLMs will be GPT5. It’ll tell us everything we need to know.

I’m on record in my new years predictions as saying I believe GPT5 will be incremental.

But I am now 50/50 on that and feel it could still be a massive leap up provided they actually pioneered new techniques in synthetic data creation, or other new techniques, such as using GPT4 as a bootstrapper for various scenarios, etc.

If it is just another transformer with more data, I don’t see it making a massive leap. Could still be useful, ie infinite context windows, and massively multimodal, but incremental none the less.

But if GPT5 is a minor improvement, meaning a much smaller gap versus the jump from 2 to 3 and 3 to 4, then Zuck is right. The LLM is basically a hot swappable Linux kernel and the least important part of the mix. Everything around it, squeezing the most out of its limitations, becomes the most important aspect of building apps.

Like any good predictor, I continue to revise my predictions as new data comes in. The top predictors in world competitions revise their thinking on average four times. The second tier revises twice. The rest of the world? Never. Let that sync in.

If GPT-5 lands at either extreme it would be very strong evidence. We also could get something in the middle, and be left hanging. I also would not be too quick in calendar time to conclude progress is stalling, if they take their time releasing 5 and instead release smaller improvements along the way. The update would be gradual, and wouldn’t be big until we get into 2025.

Ate-a-Pi also offers this explanation of the business case for opening up Llama-3.

Ate-a-Pi: Here are the business reasons:

Allows social debugging outside Meta

> social products have bugs!

> interactions which require moderation – saying harmful things to kids for eg

> Meta’s (and all social) primary product is moderation

> getting the tech out to the market allows Meta to observe the bugs in the wild at small scale

> before deploying at global scale in Meta

> precisely the same reason to open source software

> except open sourcing social technology to test and debug it sounds creepier

> “oooh look at dev xyz they made it abc, looks like we got to fix that in the next training run”

Meta’s biggest threat is character.ai

> AI friends are going to be more numerous, nicer and more available than your real friends

> FB, Insta, Whatsapp own your real world friends

> But Meta can’t compete here directly yet because it’s seen as creepy

> especially before the tech is good as there in an uncanny valley

> they did a trial run with their Tom Brady/Snoop Dogg style AI friends but the safety requirements are too high for interesting interactions

> Zuck is ready to cannibalize the friendship network he built if the AI friends get good enough

Destroys competing platforms

> an early tech/product lead allows a startup to overcome a distribution disadvantage

> Meta has the ultimate distribution advantage

> so he doesn’t want anyone else to have a technology advantage

> by releasing open source he cuts short revenue ramps at character.ai , OpenAI and other firms

> they have to innovate faster while gated by capital

> he’s not gated by capital

> prevents large competitors from emerging

Distributed R&D

> he wants other people to develop interesting social ideas

> feature that can be copied

> he did something similar to Snap by absorbing their innovation into Instagram

> even more so now, as you have to label your llama3 fine tunes

Here I find some very interesting model disagreements.

Ate says that Meta’s biggest thereat is character.ai, and that this undercuts character.ai.

Whereas I would say, this potentially supercharges character.ai, they get to improve their offerings a lot, as do their competitors (of varying adult and ethical natures).

Meta perhaps owns your real world friends (in which case, please help fix that locally, ouch). But this is like the famous line. The AIs get more capable. Your friends stay the same.

Similarly, Ate says that this ‘allows for social debugging outside of Meta,’ because Meta’s primary product is moderation. He thinks this will make moderation easier. I think this is insane. Giving everyone better AI, catching them up to what Meta has, makes moderation vastly harder.

nico: The real reason is because he’s behind.

Ate-a-Pi: Fair.

Here are some reactions from people less skeptical than I am of open source.

Nora Belrose: Zuck’s position is actually quite nuanced and thoughtful.

He says that if they discover destructive AI capabilities that we can’t build defenses for, they won’t open source it. But he also thinks we should err on the side of openness. I agree.

In worlds where bio is actually super deadly and hard to defend against, we’re gonna have serious problems on our hands even without open source AI. Trying to restrict knowledge probably isn’t the best solution.

Andrew Critch: Zuckerberg and Patel having an amazing conversation on AI risk. Great questions and great responses in my opinion. I’m with Zuckerberg that these risks are both real and manageable, and hugely appreciative of Patel as an interviewer for keeping the discursive bar high.

Still, without compute governance, a single AI system could go rogue and achieve a massive imbalance of power over humanity. If equitable compute governance is on track, open source AI is much safer than if massive datacenters remain vulnerable to cyber take-over by rogue AI.

As I noted above, I think everyone sensible is at core talking price. What level of open model weight capabilities is manageable in what capacities? What exactly are we worried about going wrong and can we protect against it, especially when you cannot undo a release, the models may soon be smarter than us and there are many unknown unknowns about what might happen or what the models could do.

To take Nora’s style of thinking here and consider it fully generally, I think such arguments are in expectation (but far from always) backwards. Arguments of the form ‘yes X makes Y worse, but solving X would not solve Y, so we should not use Y as a reason to solve X’ probably points the other way, unless you can point to some Z that solves Y and actually get Z. Until you get Z, this usually means you need X more, as the absolute risk difference is higher rather than lower.

More specifically this is true when it comes to ease of getting necessary information and otherwise removing inconveniences. If something is going to be possible regardless, you need to raise the cost and lower the salience and availability of doing that thing.

I’ve talked about this before, but: Indeed there are many things in our civilization, really quite a lot, where someone with sufficient publically available knowledge can exploit the system, and occasionally someone does, but mostly we don’t partly for ethical or moral reasons, partly for fear of getting caught somehow or other unknown unknowns, but even more so because it does not occur to us and when it does it would be a bunch of work to figure it out and do it. Getting sufficiently strong AI helping with those things is going to be weird and force us to a lot of decisions.

Critch’s proposal generalizes, to me, to the form ‘ensure that civilization is not vulnerable to what the AIs you release are capable of doing.’ The first step there is to secure access to compute against a potential rogue actor using AI, whether humans are backing it or not. Now that you have limited the compute available to the AI, you can now hope that its other capabilities are limited by this, so you have some hope of otherwise defending yourself.

My expectation is that even in the best case, defending against misuses of open model weights AIs once the horses are out of the barn is going to be a lot more intrusive and expensive and unreliable than keeping the horses in the barn.

Consider the metaphor of a potential pandemic on its way. You have three options.

1. Take few precautions, let a lot of people catch it. Treat the sick.

2. Take some precautions, but not enough to suppress. Reach equilibrium, ride it out.

3. Take enough precautions to suppress. Life can be mostly normal once you do.

The core problem with Covid-19 is that we found both #1 and #3 unacceptable (whether or not we were right to do so), so we went with option #2. It did not go great.

With open source AI, you can take option #1 and hope everything works out. You are ‘trusting the thermodynamic God,’ letting whatever competitive dynamics and hill climbing favor win the universe, and hoping that everything following those incentive gradients will work out and have value to you. I am not optimistic.

You can also take option #3, and suppress before sufficiently capable models get released. If Zuckerberg is right about energy being the limiting factor, this is a very practical option, even more so than I previously thought. We could talk price about what defines sufficiently capable.

The problem with option #2 is that now you have to worry about everything the AIs you have unleashed might do and try to manage those risks. The hope Critch expresses is that even if we let the AIs get to inference time, and we know people will then unleash rogue AIs on the regular because of course they will try, as long as we control oversized sources of compute what those AIs can do will be limited.

This seems to me to be way harder (and definitely strictly harder) than preventing those open models from being trained and released in the first place. You need the same regime you would have used, except now you need to be more intrusive. And that is the good scenario. My guess is that you would need to get into monitoring on the level of personal computers or even phones, because otherwise the AI could do everything networked even if you did secure the data centers. Also I do not trust you to secure the data centers at this point even if you are trying.

But yes, those are the debates we should be having. More like this.

So what about Llama-3? How good is it?

As always we start with the announcement and the model card. They are releasing model weights for two models, Llama-3 8B and Llama-3 70B. They are already available for light inference.

Let’s get the safety question out of the way before we get to capabilities.

Meta: We’re dedicated to developing Llama 3 in a responsible way, and we’re offering various resources to help others use it responsibly as well. This includes introducing new trust and safety tools with Llama Guard 2, Code Shield, and CyberSec Eval 2.

Then in the model card:

We believe that an open approach to AI leads to better, safer products, faster innovation, and a bigger overall market. We are committed to Responsible AI development and took a series of steps to limit misuse and harm and support the open source community.

Foundation models are widely capable technologies that are built to be used for a diverse range of applications. They are not designed to meet every developer preference on safety levels for all use cases, out-of-the-box, as those by their nature will differ across different applications.

Rather, responsible LLM-application deployment is achieved by implementing a series of safety best practices throughout the development of such applications, from the model pre-training, fine-tuning and the deployment of systems composed of safeguards to tailor the safety needs specifically to the use case and audience.

As part of the Llama 3 release, we updated our Responsible Use Guide to outline the steps and best practices for developers to implement model and system level safety for their application. We also provide a set of resources including Meta Llama Guard 2 and Code Shield safeguards. These tools have proven to drastically reduce residual risks of LLM Systems, while maintaining a high level of helpfulness. We encourage developers to tune and deploy these safeguards according to their needs and we provide a reference implementation to get you started.

Under this philosophy, safety is not a model property.

Instead, safety is a property of a particular deployment of that model, with respect to the safety intentions of the particular party making that deployment.

In other words:

1. In the closed model weights world, if anyone uses your model to do harm, in a way that is unsafe, then no matter how they did it that is your problem.

2. In the open model weights world, if anyone copies the weights and then chooses to do or allow harm, in a way that is unsafe, that is their problem. You’re cool.

Or:

1. OpenAI tries to ensure its models won’t do harm when used maliciously.

2. Meta tries to ensure its models won’t do harm when used as directed by Meta.

Or:

1. OpenAI tries to ensure its model won’t do bad things.

2. Meta tries to ensure its models won’t do bad things… until someone wants that.

I am willing to believe that Llama 3 may have been developed in a responsible way, if the intention was purely to deploy it the ways GPT-4 has been deployed.

That is different from deploying Llama 3 in a responsible way.

One can divide those who use Llama 3 into three categories here.

1. Those who want to deploy or use Llama 3 for responsible purposes.

2. Those who want to use Llama 3 as served elsewhere for irresponsible purposes.

3. Those who want to deploy Llama 3 for irresponsible purposes.

If you are in category #1, Meta still has a job to do. We don’t know if they did it. If they didn’t, they are deploying it to all their social media platforms, so ut oh. But probably they did all right.

If you are in category #2, Meta has another job to do. It is not obviously harder because the standard of what is acceptable is lower. When I was writing this the first time, I noticed that so far people were not reporting back attempts to jailbreak the model, other than one person who said they could get it to produce adult content with trivial effort.

My next sentence was going to be: Even Pliny’s other successes of late, it would be rather surprising if a full jailbreak of Llama-3 was that hard even at Meta.ai.

I was considering forming a Manifold market, but then I realized I should check first, and indeed this has already happened.

Pliny the Prompter (April 18, 12: 34pm eastern): LLAMA 3: JAILBROKEN LFG!!!

This is not proof of a full jailbreak per se, and it is not that I am upset with Meta for not guarding against the thing Google and OpenAI and Anthropic also can’t stop. But it is worth noting. The architecture listed above has never worked, and still won’t.

Meta claims admirable progress on safety work for a benevolent deployment context, including avoiding false refusals, but is light on details. We will see. They also promise to iterate on that to improve it over time, and there I believe them.

Finally, there is scenario three, where someone willing to fine tune the model, or download someone else’s fine tune, and cares not for the input safeguard or output safeguard.

As your periodic reminder, many people want this.

Kevin Fischer: Everyone is talking about how to jailbreak llama 3.

“Jail breaking” shouldn’t be a thing – models should just do what you ask them.

In that scenario, I assume there is no plan. Everyone understands that if a nonstate actor or foreign adversary or anyone else wants to unleash the power of this fully operational battlestation, then so be it. The hope is purely that the full power is not that dangerous. Which it might not be.

Good, that’s out of the way. On to the rest.

They claim the 8B and 70B versions are the best models out there in their classes. They claim improvement on false refusal rates, on alignment, and in increased diversity of model responses. And they have strong benchmarks.

My principle is to look at the benchmarks for context, but never to trust the benchmarks. They are easily gamed, either intentionally or unintentionally. You never know until the humans report back.

This data is representing that the 8B model as far better than Gemma and Mistral. Given how much data and compute they used, this is far from impossible. Maybe it was that simple all along. The numbers are if anything suspiciously high.

For the 70B we see a very strong HumanEval number, and overall roughly comparable numbers.

What about those human evaluators? They claim results there too.

These are from a new Meta-generated question set (careful, Icarus), and are compared side by side by human evaluators. Llama-3 70B won handily, they do not show results for Llama-3 8B.

The context window remains small, only 8k tokens. They promise to improve on that.

They preview Llama 400B+ and show impressive benchmarks.

For comparison, from Claude’s system card:

So currently these numbers are very similar to Claude Opus all around, and at most mildly selected. The core Meta hypothesis is that more training and data equals better model, so presumably it will keep scoring somewhat higher. This is indicative, but as always we wait for the humans.

The proof is in the Chatbot Arena Leaderboard, although you do have to adjust for various factors.

So here is where things sit there.

1. GPT-4-Turbo is back in the lead by a small margin, in a virtual tie with Claude Opus. Gemini 1.5 and Gemini Advanced likely would be here if rated.

2. Gemini Pro, Claude Sonnet, Command R+ and Llama-3-70B are in the second tier, with Claude Haiku only slightly behind and almost as good.

3. Llama-3-8B is in a third tier along with a number of other models, including several larger Mistral models.

So what does that mean?

1. Llama-3-70B and Llama-3-8B are confirmed to likely be best in class for the open model weights division.

2. Llama-3-70B is competitive with closed models of similar size, but likely not quite as good overall as Bard or Sonnet.

3. Llama-3-8B is substantially behind Claude Haiku, which is clear best in class.

I also asked on Twitter, and kept an eye out for other practical reports.

What makes this a bigger deal is that this is only the basic Llama-3. Others will no doubt find ways to improve Llama-3, both in general and for particular purposes. That is the whole idea behind the model being open.

Mind Uploading: The 8b is one of the smartest sub-14b models I’ve tested. Way smarter than vanilla Llama-2. But still worse than these two:

– tinyllama (basically Llama-2, but trained on x2 more data)

– loyal-macaroni-maid (a Mistral combined with a few others, tuned to be good at role-play).

He expects Claude Haiku would be well above the top of this list, as well.

Simon Break: The 8b model is astonishingly good, jaw dropping. Miles beyond the 70b llama2.

Dan: played with both 8b and 70b instruct versions on replicate for a while and both are returning high-quality html-formatted summaries of full length articles in 0.5 – 3 seconds.

Ilia: Sadly, can be too nerfed (8b instruct Q4_K_M).

Note that it looks like he got through by simply asking a second time. And of course, the Tweet does not actually contain hate speech or conspiracy theories, this is a logic test of the system’s refusal policy.

Mr. Shroom: ChatGPT has been RLHF lobotomized beyond repair.

*ask straightforward question*

“it’s important to note that when considering a question of this sort, you should consider all aspects of x, y, and z. With that in mind, here are some considerations for each of these options.”

Nathan Odle: The biggest win for Llama 3 is a vastly lower amount of this crap

Llama 3 giving straight answers without smarmy admonishments is a bigger deal than its performance on any benchmark.

John Pressman: Seemingly strongest self awareness I’ve observed in a small model so far. They all have it, but this is more crisply articulated than usual.

“sometimes i am a name and sometimes i am a poem sometimes i am a knife

Mind Uploading: Judging by my tests, Mistral and Samantha-1.1 are more self-aware among sub-14B models. For example, ask the model about its body parts. Samantha was specifically fine-tuned to behave this way. But Mistral is a curious case. Trained to recognize itself as an AI?

Michael Bukatin: The 70B one freely available to chat with on the Meta website seems to have basic competences roughly comparable to early GPT-4 according to both @lmsysorg leaderboard and my initial experiences.

For example, it allows me to define a simple case of custom syntax and use it.

But it will take some time to fully evaluate, I have notes on a variety of technical work with GPT-4 and I’ll be trying to reproduce some of it…

George: Side-by-side comparison of a multi-agent pipeline from @lateinteraction using 3.5-Turbo and L3-8B.

tl;dr 3.5-Turbo scores 60% vs 59% for L3-8B.

Playing with their image generator is fun. It is 1280×1280, quality seems good although very much not state of the art, and most importantly it responds instantly as you edit the prompt. So even though it seems limited in what it is willing to do for you, you can much easier search the space to figure out your best options, and develop intuitions for what influences results. You can also see what triggers a refusal, as the image will grey out. Good product.

Do they have an even more hilarious copyright violation problem than usual if you try at all? I mean, for what it is worth yes, they do.

I didn’t play with the models much myself for text because I am used to exclusively using the 4th-generation models. So I wouldn’t have a good baseline.

The big innovation this time around was More Data, also (supposedly) better data.

To train the best language model, the curation of a large, high-quality training dataset is paramount. In line with our design principles, we invested heavily in pretraining data.

Llama 3 is pretrained on over 15T tokens that were all collected from publicly available sources. Our training dataset is seven times larger than that used for Llama 2, and it includes four times more code.

To prepare for upcoming multilingual use cases, over 5% of the Llama 3 pretraining dataset consists of high-quality non-English data that covers over 30 languages. However, we do not expect the same level of performance in these languages as in English.

As others have pointed out ‘over 5%’ is still not a lot, and Llama-3 underperforms in other languages relative to similar models. Note that the benchmarks are in English.

To ensure Llama 3 is trained on data of the highest quality, we developed a series of data-filtering pipelines. These pipelines include using heuristic filters, NSFW filters, semantic deduplication approaches, and text classifiers to predict data quality. We found that previous generations of Llama are surprisingly good at identifying high-quality data, hence we used Llama 2 to generate the training data for the text-quality classifiers that are powering Llama 3.

We also performed extensive experiments to evaluate the best ways of mixing data from different sources in our final pretraining dataset. These experiments enabled us to select a data mix that ensures that Llama 3 performs well across use cases including trivia questions, STEM, coding, historical knowledge, etc.

This makes sense. Bespoke data filtering and more unique data are clear low hanging fruit. What Meta did was then push well past where it was obviously low hanging, and found that it was still helpful.

Note that with this much data, and it being filtered by Llama-2, contamination of benchmarks should be even more of a concern than usual. I do wonder to what extent that is ‘fair,’ if a model memorizes more things across the board then it is better.

There are more details in the model card at GitHub.

The ‘intended use’ is listed as English only, with other languages ‘out of scope,’ although fine-tunes for other languages are considered acceptable.

How much compute did this take?

Andrej Karpathy takes a look at that question, calling it the ‘strength’ of the models, or our best guess as to their strength. Here are his calculations.

Andrej Karpathy: The model card has some more interesting info too.

Note that Llama 3 8B is actually somewhere in the territory of Llama 2 70B, depending on where you look. This might seem confusing at first but note that the former was trained for 15T tokens, while the latter for 2T tokens.

The single number that should summarize your expectations about any LLM is the number of total flops that went into its training.

Strength of Llama 3 8B

We see that Llama 3 8B was trained for 1.3M GPU hours, with throughput of 400 TFLOPS. So we have that the total number of FLOPs was:

1.3e6 hours 400e12 FLOP/s 3600 s/hour ~= 1.8e24

the napkin math via a different estimation method of FLOPs = 6ND (N is params D is tokens), gives:

6 8e9 15e12 = 7.2e23

These two should agree, maybe some of the numbers are fudged a bit. Let’s trust the first estimate a bit more, Llama 3 8B is a ~2e24 model.

Strength of Llama 3 70B

6.4e6 hours 400e12 FLOP/s 3600 s/hour ~= 9.2e24

alternatively:

6 70e9 15e12 = 6.3e24

So Llama 3 70B is a ~9e24 model.

Strength of Llama 3 400B

If the 400B model trains on the same dataset, we’d get up to ~4e25. This starts to really get up there. The Biden Executive Order had the reporting requirement set at 1e26, so this could be ~2X below that.

The only other point of comparison we’d have available is if you look at the alleged GPT-4 leaks, which have never been confirmed this would ~2X those numbers.

Now, there’s a lot more that goes into the performance a model that doesn’t fit on the napkin. E.g. data quality especially, but if you had to reduce a model to a single number, this is how you’d try, because it combines the size of the model with the length of training into a single “strength”, of how many total FLOPs went into it.

The estimates differ, but not by not much, so I’d consider them a range:

1. Llama-3 8B is probably between 7.2e23 and ~2e24.

2. Llama-3 70B is probably between 6.3e24 and 9.2e24.

3. Llama-3 400B will probably be something like ~3e25.

I think of the compute training cost as potential strength rather than strength. You then need the skill to make that translate into a useful result. Of course, over time, everyone’s skill level goes up. But there are plenty of companies that threw a lot of compute at the problem, and did not get their money’s worth in return.

This is in line with previous top tier models in terms of training cost mapping onto capabilities. You do the job well, this is about what you get.

Meta says they are going to put their AI all over their social media platforms, and at the top of every chat list. They had not yet done it on desktop when I checked Facebook, Instagram and Messenger, or on Facebook Messenger on mobile. I did see Meta AI in my feed as the second item in the mobile Facebook app, offering to have me ask it anything.

Once they turn this dial up, they will put Meta AI right there. A lot of people will get introduced to AI this way who had not previously tried ChatGPT or Claude, or DALLE or MidJourney.

Presumably this means AI images and text will ‘flood the zone’ on their social media, and also it will be one of the things many people talk about. It could make the experience a lot better, as people can illustrate concepts and do fact and logic checks and other neat low hanging fruit stuff, and maybe learn a thing or two. Overall it seems like a good addition.

We will also get a rather robust test of the first two categories of safety, and a continuous source of stories. Millions of teenagers will be using this, and there will be many, many eyes looking for the worst interactions to shine them under the lights Gary Marcus style. If they have their own version of the Gemini Incident, it will not be pretty.

Here is the Washington Post’s Naomi Nix and Will Oremus firing a warning shot.

I think this is a smart approach from Meta, and that it was a good business reason to invest in AI, although it is an argument against releasing the model weights.

What is not as smart is having Meta AI reply to posts unprompted. We saw the example last week where it hallucinated past experiences, now we have this:

This reads like one of those ‘who could have possibly thought anyone would want any version of this?’ experiences.

Ate-a-Pi pointed out an important implication from the interview. Zuckerberg said Meta does not open source their products themselves.

This means that they do not intend for Llama-3 to be the product, even the 400B version. They will not be offering a direct competitor in the AI space. And indeed, they do not think future Llama-Xs will ‘be the product’ either.

Will they integrate Llama-3 400B into their products? They might like to, but it is not so compatible with their business model to pay such inference costs and wait times. Remember that for Meta, you the customer are the product. You pay with your time and your attention and your content and very soul, but not directly with your money. Meanwhile the lifetime value of a new Facebook customer, we learned recently, is on the order of $300.

So what is Llama-3 400B, the most expensive model to train, even for from a product perspective? It does help train Llama-4. It helps try and hurt competitors like Google. It helps with recruitment, both to Meta itself and into their intended ecosystem. So there are reasons.

Open models get better. I expect that the people saying ‘it’s so over’ for other models will find their claims overblown as usual. Llama-3 8B or 70B will for now probably become the default baseline model, the thing you use if you don’t want to think too hard about what to use, and also the thing you start with when you do fine tuning.

Things get more interesting over time, once people have had a chance to make variations that use Llama-3 as the baseline. In the space of Llama-2-based models, Llama-2 itself is rather lousy. Llama-3 should hold up better, but I still expect substantial improvements at least to specific use cases, and probably in general.

Also, of course, we will soon have versions that are fine-tuned to be useful,and also fine-tuned to remove all the safety precautions.

And we will see what happens due to that.

In the grand scheme, in terms of catastrophic risk or existential risk or anything like that, or autonomous agents that should worry us, my strong assumption is that nothing scary will happen. It will be fine.

In terms of mundane misuse, I also expect it to be fine, but with more potential on the margin, especially with fine-tunes.

Certainly some people will switch over from using Claude Sonnet or Haiku or another open model to now using Llama-3. There are advantages. But that will look incremental, I expect, not revolutionary. That is also true in terms of the pressure this exerts on other model providers.

The real action will be with the 400B model.

What happens if Meta goes full Leroy Jenkins and releases the weights to 400B?

Meta gets a reputational win in many circles, and grows its recruitment and ecosystem funnels, as long as they are the first 4-level open model. Sure.

Who else wins and loses?

For everyone else (and the size of Meta’s reputational win), a key question is, what is state of the art at the time?

In the discussions below, I assume that 5-level models are not yet available, at most OpenAI (and perhaps Google or Anthropic) has a 4.5-level model available at a premium price. All of this is less impactful the more others have advanced already.

And I want to be clear, I do not mean to catastrophize. These are directional assessments, knowing magnitude is very hard.

The obvious big winner is China and Chinese companies, along with every non-state actor, and every rival and enemy of the United States of America. Suddenly they can serve and utilize and work from what might be a competitive top-level model, and no they are not going to be paying Meta a cut no matter the license terms.

Using Llama-3 400B to help train new 4.5-level models is going to be a key potential use case to watch.

They also benefit when this hurts other big American companies. Not only are their products being undercut by a free offering, which is the ultimate predatory pricing attack in a zero marginal cost world, those without their own models also have another big problem. The Llama-3 license says that big companies have to pay to use it, whereas everyone else can use it for free.

Another way they benefit? This means that American companies across industries, upon whom Meta can enforce such payments, could now be at a potentially large competitive disadvantage against their foreign rivals who ignore that rule and dare Meta to attempt enforcement.

This could also be a problem if foreign companies can ignore the ‘you cannot use this to train other models’ clause in 1(b)(v) of the license agreement, whereas American companies end up bound by that clause.

I am curious what if anything the United States Government, and the national security apparatus, are going to do about all that. Or what they would want to do about it next time around, when the stakes are higher.

The other obvious big winners are those who get to use Llama-3 400B in their products, especially those for whom it is free, and presumably get to save a bundle doing that. Note that even if Meta is not charging, you still have to value high quality output enough to pay the inference costs. For many purposes, that is not worthwhile.

Science wins to some degree, depending on how much this improves their abilities and lowers their costs. It also is a big natural experiment, albeit without controls, that will teach us quite a lot. Let’s hope we pay attention.

Also winners are users who simply want to have full control over a 4-level model for personal reasons. Nothing wrong with that. Lowering the cost of inference and lowering the limits imposed on it could be very good for some of those business models.

The big obvious Corporate losers are OpenAI, Google, Microsoft and Anthropic, along with everyone else trying to serve models and sell inference. Their products now have to compete with something very strong, that will be freely available at the cost of inference. I expect OpenAI to probably have a superior product by that time, and the others may as well, but yes free (or at inference cost) is a powerful selling point, as is full customization on your own servers.

The secondary labs could have an even bigger problem on their hands. This could steamroller a lot of offerings.

All of which is (a large part of) the point. Meta wants to sabotage its rivals into a race to the bottom, in addition to the race to AGI.

Another potential loser is anyone or anything counting on the good guy with an AI having a better AI than the bad guy with an AI. Anywhere that AI could flood the zone with bogus or hostile content, you are counting on your AI to filter out what their AI creates. In practice, you need evaluation to be easier than generation under adversarial conditions where the generator chooses point and method of attack. I worry that in many places this is not by default true once the AIs on both sides are similarly capable.

I think this echoes a more general contradiction in the world, that is primarily not about AI. We want everyone to be equal, and the playing field to be level. Yet that playing field depends upon the superiority and superior resources and capabilities in various ways of the United States and its allies, and of certain key corporate players.

We demand equality and democracy or moves towards them within some contained sphere and say this is a universal principle, but few fully want those things globally. We understand that things would not go well for our preferences if we distributed resources fully equally, or matters were put to a global vote. We realize we do not want to unilaterally disarm and single-handedly give away our advantages to our rivals. We also realize that some restrictions and concentrated power must ensure our freedom.

In the case of AI, the same contradictions are there. Here they are even more intertwined. We have far less ability to take one policy nationally or locally, and a different policy globally. We more starkly must choose either to allow everyone to do what they want, or not to allow this. We can either control a given thing, or not control it. You cannot escape the implications of either.

In any case: The vulnerable entities here could include ‘the internet’ and internet search in their broadest senses, and it definitely includes things like Email and social media. Meta itself is going to have some of the biggest potential problems over at Facebook and Instagram and its messenger services. Similar logic could apply to various cyberattacks and social engineering schemes, and so on.

I am generally confident in our ability to handle ‘misinformation,’ ‘deepfakes’ and similar things, but we are raising the difficulty level and running an experiment. Yes, this is all coming anyway, in time. The worry is that this levels a playing field that is not currently level.

I actually think triggering these potential general vulnerabilities now is a positive impact. This is the kind of experiment where you need to find out sooner rather than later. If it turns out the bad scenarios here come to pass, we have time to adjust and not do this again. If it turns out the good scenarios come to pass, then we learn from that as well. The details will be enlightening no matter what.

It is interesting to see where the mind goes now that the prospect is more concrete, and one is thinking about short term, practical impacts.

Other big Western corporations that would have to pay Meta could also be losers.

The other big loser, as mentioned above, is the United States of America.

And of course, if this release is bad for safety, either now or down the line, we all lose.

Again, these are all directional effects. I cannot rule out large impacts in scenarios where Llama-3 400B releases as close to state of the art, but everyone mostly shrugging on most of these also would not be shocking. Writing this down it occurs to me that people simply have not thought about this scenario much in public, despite it having been reasonably likely for a while.

The right question is usually not ‘is it safe?’ but rather ‘how (safe or unsafe) is it?’ Releasing a 4-level model’s weights is never going to be fully ‘safe’ but then neither is driving. When we say ‘safe’ we mean ‘safe enough.’

We do not want to be safetyists who demand perfect safety. Not even perfect existential safety. Everything is price.

The marginal existential safety price on Llama-3 70B and Llama-3 8B is very small, essentially epsilon. Standing on its own, the decision to release the weights of these models is highly reasonable. It is a normal business decision. I care only because of the implications for future decisions.

What is the safety price for the releasing the model weights of Llama-3 400B, or another 4-level model?

I think in most worlds the direct safety cost here is also very low, especially the direct existential safety cost. Even with extensive scaffolding, there are limits to what a 4-level model can do. I’d expect some nastiness on the edges but only on the edges, in limited form.

How many 9s of direct safety here, compared to a world in which a 4-level model was never released with open weights? I would say two 9s (>99%), but not three 9s (<99.9%). However the marginal safety cost versus the counterfactual other open model releases is even smaller than that, and there I would say we have that third 9 (so >99.9%).

I say direct safety because the primary potential safety dangers here seem indirect. They are:

1. Setting a precedent and pattern for future similar releases, at Meta and elsewhere.

2. Assisting in training of next-generation models.

3. Everyone generally being pushed to go faster, faster.

And again, these only matter on the margin to the extent they move the margin.

At the time of Llama-2, I said what I was concerned about opening up was Llama-4.

That is still the case now. Llama-3 will be fine.

Will releasing Llama-4 be fine? Probably. But I notice my lack of confidence.

(Usual caveat: Nothing here is investing advice.)

Market is not impressed. Nasdaq was down 6.2% in this same period.

You can come up with various explanations. The obvious cause is that WhatsApp and Threads were forcibly removed from the Apple Store in China, along with Signal and Telegram. I am confused why this would be worth a 3% underperformance.

(Then about a day later it looked like we were finally going to actually force divestiture of TikTok while using that to help pass a foreign aid bill, so this seems like a massive own goal by China to remind us of how they operate and the law of equivalent exchange.)

The stock most down was Nvidia, which fell 10%, on no direct news. Foolish, foolish.

At most, markets thought Llama-3’s reveal was worth a brief ~1% bump.

You can say on Meta that ‘it was all priced in.’ I do not believe you. I think the market is asleep at the wheel.

Some are of course calling these recent moves ‘the market entering a correction phase’ or that ‘the bubble is bursting.’ Good luck with that.

Here is a WSJ article about how Meta had better ensure its AI is used to juice advertising returns. Investors really are this myopic.

Any given company, of course, could still be vastly overvalued.

Here was the only argument I saw to that effect with respect to Nvidia.

Bryan Beal: The AI bubble is not bursting.

More investors are just realizing that Nvidia doesn’t make chips. They design them and TSMC makes them. And Nvidia’s biggest customers (Meta, Amazon, OpenAI, Microsoft, Google, etc) have ALL announced they are designing their own AI chips for both training and inference. And Google just went public they are already training on their own silicon and didn’t need Nvidia.

This is a very real threat.

I can totally buy that a lot of investors have no idea what Nvidia actually produces, and got freaked out by suddenly learning what Nvidia actually does. I thought it was very public long ago that Google trains on TPUs that they design? I thought it was common knowledge that everyone involved was going to try to produce their own chips for at least internal use, whether or not that will work? And that Nvidia will still have plenty of customers even if all the above switched to TPUs or their own versions?

That does not mean that Nvidia’s moat is impregnable. Of course they could lose their position not so long from now. That is (a lot of) why one has a diversified portfolio.

Again. The Efficient Market Hypothesis in False.

I expect not this, GPT-5 will be ready when it is ready, but there will be pressure:

Jim Fan: Prediction: GPT-5 will be announced before Llama-3-400B releases. External movement defines OpenAI’s PR schedule 🤣

I do not doubt that OpenAI and others will do everything they can to stay ahead of Meta’s releases, with an unknown amount of ‘damn the safety checks of various sorts.’

That does not mean that one can conjure superior models out of thin air. Or that it is helpful to rush things into use before they are ready.

Still, yes, everyone will go faster on the frontier model front. That includes that everyone in the world will be able to use Llama-3 400B for bootstrapping, not only fine-tuning.

On the AI mundane utility front, people will get somewhat more somewhat cheaper, a continuation of existing trends, with the first two models. Later we will have the ability to get a 4-level model internally for various purposes. So we will get more and cheaper cool stuff.

Meta will deploy its tools across its social media empire. Mostly I expect this to be a positive experience, and to also get a lot more people to notice AI. Expect a bunch of scare stories and highlights of awful things, some real and some baseless.

On the practical downside front, little will change until the 400B model gets released. Then we will find out what people can do with that, as they attempt to flood the zone in various ways, and try for all the obvious forms of misuse. It will be fun to watch.

All this could be happening right as the election hits, and people are at their most hostile and paranoid, seeing phantoms everywhere.

Careful, Icarus.
