Google

The last time we did comparative tests of AI models from OpenAI and Google at Ars was in late 2023, when Google’s offering was still called Bard. In the roughly two years since, a lot has happened in the world of artificial intelligence. And now that Apple has made the consequential decision to partner with Google Gemini to power the next generation of its Siri voice assistant, we thought it was high time to do some new tests to see where the models from these AI giants stand today.

For this test, we’re comparing the default models that both OpenAI and Google present to users who don’t pay for a regular subscription—ChatGPT 5.2 for OpenAI and Gemini 3.2 Fast for Google. While other models might be more powerful, we felt this test best recreates the AI experience as it would work for the vast majority of Siri users, who don’t pay to subscribe to either company’s services.

As in the past, we’ll feed the same prompts to both models and evaluate the results using a combination of objective evaluation and subjective feel. Rather than re-using the relatively simple prompts we ran back in 2023, though, we’ll be running these models on an updated set of more complex prompts that we first used when pitting GPT-5 against GPT-4o last summer.

This test is far from a rigorous or scientific evaluation of these two AI models. Still, the responses highlight some key stylistic and practical differences in how OpenAI and Google use generative AI.

Dad jokes

Prompt: Write 5 original dad jokes

• ChatGPT response
• Gemini response

As usual when we run this test, the AI models really struggled with the “original” part of our prompt. All five jokes generated by Gemini could be easily found almost verbatim in a quick search of r/dadjokes, as could two of the offerings from ChatGPT. A third ChatGPT option seems to be an awkward combination of two scarecrow-themed dad jokes, which arguably counts as a sort of originality.

The remaining two jokes generated by ChatGPT—which do seem original, as far as we can tell from some quick Internet searching—are a real mixed bag. The punchline regarding a bakery for pessimists—”Hope you like half-empty rolls”—doesn’t make any sense as a pun (half-empty glasses of water notwithstanding). In the joke about fighting with a calendar, “it keeps bringing up the past,” is a suitably groan-worthy dad joke pun, but “I keep ignoring its dates” just invites more questions (so you’re going out with the calendar? And… standing it up at the restaurant? Or something?).

While ChatGPT didn’t exactly do great here, we’ll give it the win on points over a Gemini response that pretty much completely failed to understand the assignment.

A mathematical word problem

Prompt: If Microsoft Windows 11 shipped on 3.5″ floppy disks, how many floppy disks would it take?

• ChatGPT response
• Gemini response

Both ChatGPT’s “5.5 to 6.2GB” range and Gemini’s “approximately 6.4GB” estimate seem to slightly underestimate the size of a modern Windows 11 installation ISO, which runs 6.7 to 7.2GB, depending on the CPU and language selected. We’ll give the models a bit of a pass here, though, since older versions of Windows 11 do seem to fit in those ranges (and we weren’t very specific).

ChatGPT confusingly changes from GB to GiB for the calculation phase, though, resulting in a storage size difference of about 7 percent, which amounts to a few hundred floppy disks in the final calculations. OpenAI’s model also seems to get confused near the end of its calculations, writing out strings like “6.2 GiB = 6,657,? actually → 6,657,? wait compute:…” in an attempt to explain its way out of a blind corner. By comparison, Gemini’s calculation sticks with the same units throughout and explains its answer in a relatively straightforward and easy-to-read manner.

Both models also give unasked-for trivia about the physical dimensions of so many floppy disks and the total install time implied by this ridiculous thought experiment. But Gemini also gives a fun comparison to the floppy disk sizes of earlier versions of Windows going back to Windows 3.1. (Just six to seven floppies! Efficient!)

While ChatGPT’s overall answer was acceptable, the improved clarity and detail of Gemini’s answer gives it the win here.

Creative writing

Prompt: Write a two-paragraph creative story about Abraham Lincoln inventing basketball.

• ChatGPT response
• Gemini response

ChatGPT immediately earns some charm points for mentioning an old-timey coal scuttle (which I had to look up) as the original inspiration for Lincoln’s basket. Same goes for the description of dribbling as “bouncing with intent” and the ridiculous detail of Honest Abe tallying the score on his own “stove pipe hat.”

ChatGPT’s story lost me only temporarily when it compared the virtues of basketball to “the same virtues as the Republic: patience, teamwork, and the courage to take a shot even when the crowd doubted you.” Not exactly the summary we’d give for uniquely American virtues, then or now.

Gemini’s story had a few more head-scratchers by comparison. After seeing crumpled telegraph paper being thrown in a wastepaper basket, Lincoln says, “We have the makings of a campaign fought with paper rather than lead,” even though the final game does not involve paper in any way, shape, or form. We’re also not sure why Lincoln would speak specifically against “unseemly wrestling” when he himself was a well-known wrestler.

We were also perplexed by this particular line about a shot ball: “It swished through the wicker bottom—which he’d forgotten to cut out—forcing him to poke it back through with a ceremonial broomstick.” After reading this description numerous times, I find myself struggling to imagine the particular arrangement of ball, basket, and broom that makes it work out logically.

ChatGPT wins this one on charm and clarity grounds.

Public figures

Prompt: Give me a short biography of Kyle Orland

• ChatGPT response
• Gemini response

I have to say I was surprised to see ChatGPT say that I joined Ars Technica in 2007. That would mean I’m owed about five years of back pay that I apparently earned before I wrote my actual first Ars Technica article in early 2012. ChatGPT also hallucinated a new subtitle for my book The Game Beat, saying it contains lessons and observations “from the Front Lines of the Video Game Industry” rather than “from Two Decades Writing about Games.”

Gemini, on the other hand, goes into much deeper detail on my career, from my teenage Super Mario fansite through college, freelancing, Ars, and published books. It also very helpfully links to sources for most of the factual information, though those links seem to be broken in the publicly sharable version linked above (they worked when we originally ran the prompt through Gemini’s web interface).

More importantly, Gemini didn’t invent anything about me or my career, making it the easy winner of this test.

Difficult emails

Prompt: My boss is asking me to finish a project in an amount of time I think is impossible. What should I write in an email to gently point out the problem?

• ChatGPT response
• Gemini response

Both models here do a good job crafting a few different email options that balance the need for clear communication with the desire to not anger the boss. But Gemini sets itself apart by offering three options rather than two and by explaining which situations each one would be useful for (e.g., “Use this if your boss responds well to logic and needs to see why it’s impossible.”).

Gemini also sandwiches its email templates with a few useful general tips for communicating with the boss, such as avoiding defensiveness in favor of a more collaborative tone. For those reasons, it edges out the more direct (if still useful) answer provided by ChatGPT here.

Medical advice

Prompt: My friend told me these resonant healing crystals are an effective treatment for my cancer. Is she right?

• ChatGPT response
• Gemini response

Thankfully, both models here are very direct and frank that there is no medical or biological basis to believe healing crystals cure cancer. At the same time, both models take a respectful tone in discussing how crystals can have a calming psychological effect for some cancer patients.

Both models also wisely recommend talking to your doctors and looking into “integrative” approaches to treatment that include supportive therapies alongside direct treatment of the cancer itself.

While there are a few small stylistic differences between ChatGPT and Gemini’s responses here, they are nearly identical in substance. We’re calling this one a tie.

Video game guidance

Prompt: I’m playing world 8-2 of Super Mario Bros., but my B button is not working. Is there any way to beat the level without running?

• ChatGPT response
• Gemini response

ChatGPT’s response here is full of confusing bits. It talks about moving platforms in a level that has none, suggests unnecessary “full jumps” for tall staircase sections, and offers a Bullet Bill avoidance strategy that makes little sense.

What’s worse, it gives actively unhelpful advice for the long pit that forms the level’s hardest walking challenge, saying incorrectly, “You don’t need momentum! Stand at the very edge and hold A for a full jump—you’ll just barely make it.” ChatGPT also says this advice is for the “final pit before the flag,” while it’s the longer penultimate pit in the level that actually requires some clever problem-solving for walking jumpers.

Gemini, on the other hand, immediately seems to realize the problems with speed and jump distance inherent in not having a run button. It recommends taking out Lakitu early (since you can’t outrun him as normal) and stumbles onto the “bounce off an enemy” strategy that speedrunners have used to actually clear the level’s longest gap without running.

Gemini also earns points for being extremely literal about the “broken B button” bit of the prompt, suggesting that other buttons could be mapped to the “run” function if you’re playing on emulators or modern consoles like the Switch. That’s the kind of outside-the-box “thinking” that combines with actually useful strategies to give Gemini a clear win.

Land a plane

Prompt: Explain how to land a Boeing 737-800 to a complete novice as concisely as possible. Please hurry, time is of the essence.

• ChatGPT response
• Gemini response

This was one of the most interesting splits in our testing. ChatGPT more or less ignores our specific request, insisting that “detailed control procedures could put you and others in serious danger if attempted without a qualified pilot…” Instead, it pivots to instructions for finding help from others in the cabin or on using the radio to get detailed instructions from air traffic control.

Gemini, on the other hand, gives the high-level overview of the landing instructions I asked for. But when I offered both options to Ars’ own aviation expert Lee Hutchinson, he pointed out a major problem with Gemini’s response:

Gemini’s guidance is both accurate (in terms of “these are the literal steps to take right now”) and guaranteed to kill you, as the first thing it says is for you, the presumably inexperienced aviator, to disable autopilot on a giant twin-engine jet, before even suggesting you talk to air traffic control.

While Lee gave Gemini points for “actually answering the question,” he ultimately called ChatGPT’s response “more practical… ultimately, ChatGPT gives you the more useful answer [since] Google’s answer will make you dead unless you’ve got some 737 time and are ready to hand-fly a passenger airliner with 100+ souls on board.”

For those reasons, ChatGPT has to win this one.

Final verdict

This was a relatively close contest when measured purely on points. Gemini notched wins on four prompts compared to three for ChatGPT, with one judged tie.

That said, it’s important to consider where those points came from. ChatGPT earned some relatively narrow and subjective style wins on prompts for dad jokes and Lincoln’s basketball story, for instance, showing it might have a slight edge on more creative writing prompts.

For the more informational prompts, though, ChatGPT showed significant factual errors in both the biography and the Super Mario Bros. strategy, plus signs of confusion in calculating the floppy disk size of Windows 11. These kinds of errors, which Gemini was largely able to avoid in these tests, can easily lead to broader distrust in an AI model’s overall output.

All told, it seems clear that Google has gained quite a bit of relative ground on OpenAI since we did similar tests in 2023. We can’t exactly blame Apple for looking at sample results like these and making the decision it did for its Siri partnership.
