It will be valuable to have two types of benchmarks: ones that evolve alongside the models and ones that never change. You probably can't get historical stability and resistance to flooding and training on at least some parts of it from the same test
Like Simon concludes the article, the main use of this isn't to say which model is "better", but to try and poke at the model to sort out things like quality vs cost vs speed.
So I put together a quick comparison of the last couple iterations of Opus, Fable and now Kimi.
It's incredible Simon still believes pelicans on bikes aren't part of the training set, despite hundreds of them on blogs, forums, and Github. Stuff we put in our company blog shows up known by LLMs 6 months later, and we have 1000x less traffic than Simon's own website
The pelicans are still all rubbish. If they make it into the training set it doesn't help the models produce better pelicans, if anything it will make them perform worse!
Simon has stated a few times that he knows it’s possible that pelicans could be in the training sets. He also has other tests he doesn’t share publicly. He’s just a fan of pelicans.
From the article it doesn't even sound like he cares about pelicans at all, and doesn't think they are a good way to compare models anymore ... but people are used to seeing the test now, and it does serve as a common "hello world" unit of work.
the nature of the test was to see if the models can effectively compose an image of a novel concept outside the training set. If they are trained on it, it ceases to be an interesting test to some extent.
I would urge you to re-read the blog post you are commenting on. It pretty clearly explains how it is an interesting test independently of "see[ing] if the models can effectively compose an image of a novel concept outside the training set".
it's still interesting because there's no pelican-on-bike model, and if you're training a model well enough, then it should be obvious when a model has reached "AGI" or whatever.
More to it, the actual bloody companies are using them as a reference. Maybe it’s a 3d version, not an svg - but it clearly shows they’re on the radar of these companies.
Respectfully, did you? The comment was specific to doubting the believe simonw has that labs are not training [0] specifically for this task, which is exactly what simonw wrote in the post [1], that it is a believe of his that they don't. He did not mention any kind of evidence or any piece of information that would indicate that the commenter didn't read the blog post.
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.
Maybe it gets posted every time because besides a personal believe by the person popularising this "benchmark", there is no reason to assume that certain labs aren't intentionally training to game this and every other lab at least unintentionally gets improvements for this specific combination of animal and action because the internet is full of both good and bad examples, often ranked, which does inevitably become training data.
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.
> I have shared examples of certain models by certain labs doing far better on the pelican cycling vs other, similar prompts
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).
We do. People who, for example, memorize question banks to pass certification tests without knowing the underlying material are equally frowned upon for not having the problem solving skills that they purport to.
I'll leave the contrasts between LLMs and people to the well-written sibling comments.
This is a sight-reading test. If a musician practices a piece for thousands of hours, it would no longer be an effective sight reading / creativity test. The purpose of the test was to see how models would compose something novel requiring the ability to compose orthogonal, normally unrelated, components into a coherent image.
They can be in the training set but not deliberately trained for. There may be a lot of people posting pelican svgs, but not typically because they're high quality and worth replicating.
> How does the prompt “Generate an SVG of a pelican riding a bicycle” add up to 95 input tokens? OpenAI’s tokenizer counts 10, Anthropic’s counts 10 for Opus 4.6, 30 for Opus 4.7 and 25 for Sonnet 5/Fable 5. Prompting “hi” to Kimi K3 counted 86 tokens, suggesting there may be an 85 token hidden system prompt. It refused to leak it though.
3T is impressive, but parameter count seems to be less important than I thought.
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.
The idea is not to use pelicans on bikes but a similarly random non-sensical prompts: crows on scooters, squirrels in a moon rover etc. Then pick another one for another for next cross-llm evaluation.
I wonder how the Chinese labs are training a 3 trillion parameter model on what has to be vastly smaller compute resources. If the U.S. compute advantage is persistent, it's hard to imagine that Chinese labs will be able to keep pace forever, as a matter of physics, but... so far they seem to be doing just fine.
Do any of the vision models render the SVG and look at the result.
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.
My personal benchmark for new models has been to compare video making skills with something like remotion. Usually reveals if they have any "taste" or outside the box thinking.
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.
And on creativity at least visually, Gemini 3.1 pro is somehow still up there. But its really hindered by its inability to use tool calls effectively or make a long term plan.
Another day, another model and another pelican :-)
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?
You say it's performative joke, but it all depends what you're using model for. So far the rule has been quite straightforward, better models consistently renders pelican in higher quality, I've yet to see an exception. It is also a good enough (for me at least) test for "taste" the model has.
> better models consistently renders pelican in higher quality
The article literally avoid making this argument and gives counterexamples to this statement.
Imagine what amazing SVG generators we could have if Simon had randomized the target image from the start (and companies wouldn't just overfit on pelicans).

K3 is as expensive as Sonnet, not great at writing English, is handing IP back to the Chinese, and once open source will be difficult to run at scale without the compute that OpenAI and Anthropic have largely grabbed.
Sorry, how again is this the end of the frontier labs?
According to some benchmarks has the coding capability of Opus at the price of Sonnet, supposedly will be open weights and is not subject to random trade wars with allied states.
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.
they're comparing to similar capability llm models, not humans. If one dishwasher does job at similar quality as another dishwasher, but using 30% more water and energy, you wouldn't compare to how much it costs human to do the same work, it would make no sense.
> they're comparing to similar capability llm models, not humans
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.
Well first of all, any non-trivial use of LLMs is going to be orders of magnitude more tokens than this, usually multiple millions at minimum. Benchmarks are just benchmarks after all.
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...
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

I've not seen that myself yet.
"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!"
I'll leave the contrasts between LLMs and people to the well-written sibling comments.
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...

There seems to be more to producing a better model than brute forcing parameter count after all.

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.
what they do have are many different pelicans and people helpfully rating them in the comments.
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?

> 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.
You still need an OpenRouter API Key and be careful this can burn quite a bit of money.
