In the same timescale, model capabilities across the board have only meaningfully improved in places where the labs are focusing their training efforts.
Moreover, they have a uniform style, even though your prompt doesn’t ask for one. There's no model going rogue and producing a watercolour of a pelican. They’re all rendered in an approximately uniform style, even though the svg format has a basically unlimited possibility space.
Blue sky and green grass aren't that surprising, but the color and direction are interesting.
When I finally build the proper gallery I'll throw in a few other creature-vehicle combinations, and track some characteristics like which direction, color of bicycle, general pelican geometry etc. It will be interesting to see if other creatures end up with coincidentally similar design choices or if that's unique to the pelican-bicycle combination.
So the direction may not be that interesting!
Before that it was vertical (although the ordering of the columns was right to left).

For example: "generate an SVG of a chessboard seen from a 45 degree angle slightly higher POV" or "generate an SVG of a basketball court from a TV broadcast perspective".
I find Gemini is still the best at creating SVGs.
I haven't seen many AI works that produces a pelican on a bicycle done in a "Ligne Claire" style, for example.
I guess AI's narrows down the output probability space drastically and converge on some agreed upon aesthetics. Works great for computer programs but bad for art.
You would not expect that to happen if the models trained on the unrecognizable mess, right?
> model capabilities across the board have only meaningfully improved in places where the labs are focusing their training efforts
And the labs clearly did focus on improving image rendering.
> they have a uniform style
SVG output from LLMs always looks like that. It looked that way from the beginning; no LLM ever produced a watercolor when asked for SVG output. They all render the prompted element centered in the picture. They all tend to draw things going from left to right, and so on.

You haven't seen their final form [1]
[1] final form is a frontend/react/let's not talk about it, library - it caused a great deal of PTSD to me and my previous company's team due to its dogmatic preference for "we use these axioms, end of story", over practical utility - so it was quite challenging to do state of the art tasks such as nested form fields (e.g. 'user.address.personal.line-1'). The PTSD it caused made us all block out the memories, I suppose. But - it had zero dependencies. That is what mattered. It kept us going. We weren't reaching for more. We had plenty of time.
And thank god for that. Because I'd forgotten my watch in California - and this was in Tokyo [2]
[2] a joke within a joke about Jensen's Kyoto gardener story. Beautiful story, drowned out by WatchGate memes. Why can't jokes have layers? Models have trillions. If you miss 100% of the jokes you don't make, make all the jokes. Someone will laugh (eventually, maybe?) Even if it's: "this person + comedy club = full secret service detail". If someone laughs at that - at my own expense? I don't mind. They laughed. I know this is a gibberish, off-topic message - it's also a human message. I just felt we need more such things in our lives these days.
PS: have you physically seen a pelican in real life? (not a joke)
We have several thousand living 15 minutes walk from our house. I recently started adding my wildlife photography (from iNaturalist) to my blog, so I'm posting several new pelican photos a week at the moment: https://simonwillison.net/search/?q=pelican&type=beat%3Asigh...
Your pelican output is thus both in the training set and yet still outside the capability of the model architecture.
And so you are tracking both the capability of the training and also the capability of the querying!
When you receive your first outstanding pelican it will track a gain of capability.
(btw I first mentioned simonw-pelican-into-training-set in May 2025 on twitter.)
My 3D-egyptology-explainer showed a massive uplift for Kimi K3 and this tracks a much improved 3D capability.
I have shared examples of certain models by certain labs doing far better on the pelican cycling vs other, similar prompts. Just operating on a feeling that labs don't optimise for this (as mentioned, even if they don't training data is filled with these) is not solid enough that criticism shouldn't be leveraged when it comes up.
Please share those again!
One of the things I'm most looking forward to is a lab producing a model that creates a really great pelican riding a bicycle and then a terrible sloth riding a skateboard (or whatever).
I've not seen that myself yet.
> [...] a really great pelican riding a bicycle and then a terrible sloth riding a skateboard [...]
Happy to play ball. You made a blog post a few weeks back on one of the Qwen models with the eye-catching title "Qwen3.6-35B-A3B on my laptop drew me a better pelican than Claude Opus 4.7" [1].
Here is what Qwen3.6-35B-A3B via Openrouter provided for a sloth riding a skateboard: https://imgur.com/a/Dy8fvR5
Like Grok 4 Fasts attempt at a mushroom in a rowboat, it is barely recognisable as anything despite both Qwen3.6-35B-A3B and Grok 4 Fast having no issue with more popular (i.e. benchmarked) examples. Whether this is a case of training data being unsanitized or intentional benchmark targeted training, I cannot say, but it is the case.
And here is Opus 4.7, again via Openrouter: https://imgur.com/a/Qus1Enf
A massive delta in favour of Opus 4.7, despite the pelican Qwen3.6-35B-A3B produced being noticeably better as you rightly pointed out. What does that tell us? Whether intentional or not (with such deltas, I do have my suspicions), any eval with such a delta is clearly polluted and can not be a source of information, especially as its continued existence does hinge on you testing similar prompts in private as a sanity check, yet by your own admission never noticing the plainly apparent delta in quality. I specifically stuck with the skateboarding sloth too, to keep it as fair as possible and found this in less than 5 minutes...
I would not critique your use of this fun benchmark the way I tend to if I did not have evidence to back up my position, including private evals beyond SVGs that I can reliably use to point out major deviations between what a models claimed performance is according to major benchmarks vs the actual performance outside these known test cases.
I will also say that while I have a lot to be critical of regarding Anthropics modus operandi, especially how they present interesting findings like their j-space work, which I found was irresponsibly anthropomorphic in their reporting, especially as this wasn't a first in model interpretability, but mainly a leap due to being applied to a larger model, but of all the labs, they are the ones that never underperform my evals vs public ones and they appear to strictly keep their training data sanitised.
Happy to discuss public vs private evals and the merit of each if you'd like, I do appreciate your reporting in general but just think the SVG benches have become evidently polluted, which is also why even simple queries in my benchmarks are private. Just saw Thinking Machines Inkling model succeed in certain queries that neither Fable 5, nor GPT-5.6 Sol on any reasoning level managed, which I feel is valuable to truly gauge where we are at. Informs my work with models, my views of the industry and my assessment of the future these tools have, along with how to best implement them to enable better UX.
Did you read either the post or the comment it was referencing?
On the note of training on SVGs, I have seen some labs models outperform when prompted for SVGs of certain animal and action combinations (pelican on bike, panda eating burger, etc.) compared to other similarly outlandish prompts for SVG output that are not part of widely reported benchmarks, even shared evidence one of the last times this came up on here.
[0] ... incredible Simon still believes ...
[1] I’m still not convinced that labs ....
I'm sure all sorts of crap pelican riding bicycle SVGs have ended up in the huge crawls of data that the labs feed into their pre-training steps.
What I'm questioning here is that there are labs who have sat down and deliberately tested and tweaked the performance for this particular task, independent of general model improvements.
The one exception here is Gemini, who have clearly invested a lot of effort in SVG tasks. I have no idea if my stupid benchmark influenced that decision!
Gemini have boasted about how good they are at pelicans riding bicycles, frogs on penny-farthings, giraffes driving a tiny car, ostriches on roller skates, turtles kickflipping skateboards, and dachshunds driving a stretch limousine. So if they trained for the test they did at least expand it a whole bunch! https://twitter.com/JeffDean/status/2024525132266688757
Given the massive delta easily reproducible with some models, is it really doubtful that certain labs have not: https://news.ycombinator.com/item?id=48951229
We are going from pretty good pelican to jumbled mess with a similarly silly, but different prompt across multiple models from multiple labs, both Western and Eastern, both Open Weight and Closed.
"That artist saw a pelican at the beach once!" [cue the outrage] "He's not a real artist, he's a cheater and produces nothing original!"
Plus obviously humans can still overfit to a specific style of test.
This is quite possibly reasoning-effort prompt which is injected before the opening <think> token whenever you set a custom reasoning effort, see e.g. DeepSeek-V4 max mode prompt: https://huggingface.co/deepseek-ai/DeepSeek-V4-Pro/blob/main...
So I put together a quick comparison of the last couple iterations of Opus, Fable and now Kimi.
Kimi is cheapest by 5x but also slowest by 2x
GLM is half the size of DeepSeek but costs four times as much, and beats it on every benchmark.
I'm not an expert on this stuff but it seems to be the attention mechanism. DeepSeek were bragging about how cheap they made it. But if you cut costs on attention you get worse results with way more parameters.
If I had to guess it seems to be the difference between memory (params) and intelligence (attention density). I think you need both.
Deepseek V4 Flash, the 284B model, is roughly equivalent to launch GLM 5, the 744B [sic] model.
I built a whole ELO scoring mechanism a while back, described here: https://simonwillison.net/2025/Jun/6/six-months-in-llms/#ai-...
I probably should spend some time on this now, even though the benchmark itself is feeling a bit stale. There's still a lot of demand for a gallery!

There seems to be more to producing a better model than brute forcing parameter count after all.
Perhaps more importantly can they do that during reinforcement training. Learning how to critically analyse the appearance of what it generates would be quite useful.
Manually feeding images back to models has been hilariously bad in the past which suggests that relating something it sees to something it wrote is not an ability it is very good at.
I'm starting to not trust any "benchmarks" when it comes to frontier models at least. As an example Sol feels the most "gets stuff done" but has zero taste, or any capability to surprise.
And for frontier models I go one step ahead and try to recreate a complex animation video, with the ability for the model to review its own work. And at this Fable is still the top one. Ex: https://www.youtube.com/watch?v=uDAeAuYyl0E (recreation of Claude announcement video) and https://www.youtube.com/watch?v=cSsVNtGPOIg (recreation of a fireship video). Sol did something similar but you can instantly tell its AI slop from very small things, and it just has no narrative or thought put into the writing.
https://mesmer.tools/benchmarks/ai-video-generation , I usually put basic ones here.
We may be boiling the oceans but at least we are finally getting some good SVGs of pelicans on bicycles.
I can't help but wonder where is the trend going? What will we have in five years? Maybe it will all have puttered out, and we will have moved to the next thing? Or maybe the prompt then will be "make a pelican ride a bicycle", and out will come the genetic code for a giant pelican with extremities suitable for a handle bar and pedals, and an inborn affinity to ride bicycles?
> What will we have in five years? Maybe it will all have puttered out, and we will have moved to the next thing?
We will just have more of the same.
I take exception to that! It's a performative joke for attention that works far more widely than just Hacker News.
New hotness: pelicanmaxxing
what they do have are many different pelicans and people helpfully rating them in the comments.
You still need an OpenRouter API Key and be careful this can burn quite a bit of money.
You’re reading a personal blog and complaining about an open source personal project he runs and distributes for free. He’s allowed to talk about his personal work on his personal blog. Especially considering the cli utility he talks about is directly related to the post.
Imagine complaining about someone generating valuable content for free and not packaging it to your personal tastes.
Why does Kimi not use a "Double Cheese Whammy" branding for "their" butchered and stolen IP?
Sorry, how again is this the end of the frontier labs?
Competition is always good.
Engineers get unbelievably silly about evaluating costs of things.
"The tokens are so expensive!" Oh my sweet child, how much would even the least capable human effort cost? This is what the executives properly understand that the programmers don't.
25 cents is 10x the cost of 2.5 cents, but it's still extremely cheap for the product. It's very much the wrong comparison for a world where the primary competition is still humans who need to eat, and it treats percentage differences as more important than absolute differences when the opposite is true.
Secondly, humans vs LLMs are apples vs oranges. It makes no more sense to compare human costs vs LLM costs as it would have to compare human costs vs calculator costs. LLMs are faster and cheaper but extremely different beasts with different limitations. Humans do not one-shot SVGs of pelicans riding bicycles, and they do not charge in tokens.
Comparing LLM cost efficiency is not something that should need to be defended. It's quite straightforward and reasonable...
