My personal AI benchmark: “Generate an SVG of a frog with a Habsburg jaw”

I'm afraid you'll need to look up "Habsburg" yourself.

by DimitriBouriez

8/3/2026 at 7:52:58 AM

Nathan is right though. It specifies a Habsburg jaw, not that the frog is a Habsburg king/prince. It's understandable that the LLM will hallucinate a king from this, but it isn't what's being asked of it.

When I ask to create an image of a smartphone, it will most likely show the front and while it's turned on, even though it's not mentioned. For a person, it will add clothing.

Adding things that are not explicitly stated in the prompt but that are probable are the main benefit of AI, as far as I am concerned.

An artist given the same prompt would likely do something similar.

by rcxdude

It's not hallucination. The prompt lacks details and given that an AI or a human has some artistic freedom. After all, that is why current AI is usable at all.

I thought this was great, and hilarious. Kudos to Opus 5, I thought it was the only one that came close to passing. Interestingly, I thought many of the failures drew the frog face OK, and they had some type of big blob for the jaw, so they knew "Hapsburg jaw" meant a protruding jaw, but it wasn't really connected to the frog face in any way that made sense.

Small side note, the first gemini-2.5-pro one totally reminded me of some sad faced meme or Pepe the frog from somewhere. Anyone know what I'm referring to, tried to find it.

Curious that none of the attempts draw the frog from side profile. If i have to draw this i would immediately know that drawing a recognisable frog is the easy part of job. Expressing a particular jaw shape and melding it on the frog is the hard part. And jaw shapes are more prominent from the side.

Even absence of thinking this through you would think that some frogs will be from the front, some from the side. Just by chance. And yet all appears to go for the harder pose.

by krisoft

8/3/2026 at 12:31:26 AM

When I asked ChatGPT, it gave me a side profile, first as a PNG which was good and then I asked again for an SVG and it obliged, doing a version of what it produced but it was bad.

SVG: https://jostylr.com/imgs/frog_habsburg_jaw.svg

My personal benchmark is a directory containing a bunch of research papers on the physics of popping popcorn kernels, and a prompt about creating high fidelity, photo realistic 3D models of all the different kinds of popped kernels. Fable (surprisingly? unsurprisingly?) refused to do it last time I tried, and the results from other models are, well, fine, but there's still plenty of headroom on this particular one.

by abound

LLMs don’t work particularly well in 3d applications in my experience. Every new model release I’ll ask one for help with my path tracer and results are horrid.

by wren6991

Arguably, a royal portrait is a misinterpretation of the prompt, since it's just asking for a specific facial feature. But I guess you could look at it as a bit of artistic license.

How do models approach SVG generation? In one version, I imagine them actually trying to reason about them as an LLM. In another, I imagine something closer to a GAN.

by dehrmann

8/3/2026 at 12:29:36 AM

I would be interested to hear more about that too. SVGs seem to be one of the biggest challenges- it has to write reasoned code rather than simply find averages of rasterized pixels. One thing I noticed is that none of the models chose to draw the frog in profile which would have made the jaw shape more prominent. To me that suggests the reasoning is very limited: "draw a frog" and "add feature X". The statistically average frog in the SVG training data is apparently front-facing. I tried the prompt in ChatGPT images (not SVG) and it produced a photo-realistic image of the frog in profile, showing the jaw clearly. Then when I asked it to convert the image to a cartoon vector it fell back to a generic front portrait template similar to those shown in the benchmark, nothing like the profile it had just produced.

Here is GLM 5.2 (https://codeinput.com/s/HAO0qTxw2ia) which is still inferior to Opus. I can't find Qwen 3.8 which now is my daily driver replacing GLM. This SVG test matches my experience when working with the different models. The other models can get the details right but their output is structured in a way that makes little or no sense.

I also did a timeline from 4.7 to 5.2: https://codeinput.com/s/7oK2IIA7qRO The improvements in models looks much less impressive with this test.

by epolanski

8/3/2026 at 1:55:37 AM

The vendors like to toss around terms like “thinking” or “reasoning” to encourage prospective buyers to anthropomorphize models. These challenges are a visceral reminder that none of those marketing claims accurately describe was LLMs do: they’ll happily return things even the worst human illustrator would never hand in and make errors showing that there’s no model of the world behind anything they do.

That doesn’t mean there are no ways to use them productively but rather that you should keep in mind that the same model will happily give you code or a decision with the same level of error unless you have carefully setup a QA regimen to prevent that.

> That doesn’t mean there are no ways to use them productively but rather that you should keep in mind that the same model will happily give you code or a decision with the same level of error unless you have carefully setup a QA regimen to prevent that.

The standard retort seems to be "this is also true of a large proportion of humans". But I think it's clear that there are differing patterns in how humans vs. models err on various tasks.

by zahlman

8/3/2026 at 11:04:41 AM

Exactly right: it’s not that humans were perfect-I’ve seen too many write-offs from the big consulting companies to ever say that—but that the pattern of errors is different and any intuition you have around that will not be correct in the LLM era.

by acdha

8/3/2026 at 2:29:24 AM

Unless the LLM has an SVG renderer in its toolbox, it's like asking a human to draw while blindfolded. It's amazing if they can do it well, but it's practically meaningless.

by Mindless2112

8/2/2026 at 10:25:00 PM

For me this looks ideological (or even political), not practical. The theory is that LLMs are approaching general intelligence (whatever that means) and that the more generic of a task they can perform—no matter how badly—the closer we are to AGI.

Specialized models can do this a lot better and for far cheaper then LLMs, but because people are so politically invested in a single statistical model being able to outperform a human on every metric (no matter how expensive the compute), then we get these ridiculous benchmarks.

Mine is any variations on mammoths in various situations, or anthropomorphic. Since mammoths are invariably majestically going from one place to another in any of the books, models have hard time imagining anything but that.

by AlienRobot

8/2/2026 at 7:42:08 PM

I think this one has advantages over the “pelican riding a bicycle” one because it hinges on an anatomical feature that many models associate with royalty, “habsburg” being a lineage and “habsburg jaw” being an anatomical feature.

Seven of fourteen models silently imported royalty into a prompt that named only an anatomical feature. Two of them knew they were extrapolating ("because Habsburg") and did it anyway.

Mistral returned byte-identical output across separate calls.

Gemini narrates its work in 65 comments; Llama says nothing.

If you're deciding which model to trust with instructions, "how much does it embellish beyond what I asked" and "does it behave deterministically" are directly practical questions.

8/3/2026 at 7:23:41 AM

> Two of them knew they were extrapolating ("because Habsburg") and did it anyway.

You seem to imply that they ought not to. I disagree.

I wasn't familiar with the term before this post. Having learned it, were I given the task, I think I'd be strongly tempted to do the same extrapolation.

> If you're deciding which model to trust with instructions, "how much does it embellish beyond what I asked" and "does it behave deterministically" are directly practical questions.

Agency is agency. You still need to vet what the model's output is actually permitted to control.

That would be like saying anyone with Lou Gehrig's disease must look like Lou Gehrig. So we'll have to agree to disagree here.

by thebigship

8/3/2026 at 8:07:45 PM

Well, no, I think you create a pretty clear false dichotomy there.

Certainly a person with Lou Gehrig's disease could look like Lou Gehrig; and especially in a cartoon illustration, where it's difficult to convey the point, this kind of artistic license is used specifically so that the viewer will make these kinds of associations.

I would, likely, otherwise perceive an underbite as just an underbite.

For those who don’t know a Habsburg jaw also known as mandibular prognathism, it is a genetic condition characterized by a protruding lower jaw, which was notably prevalent among members of the Habsburg royal family due to their history of inbreeding. This condition often resulted in significant facial deformities and difficulties with eating and speaking.
