Training impossibilities aside, how would you even make an optimization loop for "fun"?

Brain-computer interface, maybe. Hook a million play-testers up to the output and have it iterate. ..feels like there was a black mirror episode about that though

Black mirror is the dark version of simpsons with a bit of xkcd.

Agree. The pelican benchmark was interesting a year ago when most models struggled and a good pelican indicated an unusually capable model. Now it’s saturated and uninteresting. A good new benchmark should have awful performance to start and there should be a lot of headroom for improvement. This benchmark is also intentionally difficult and requires the LLM to develop the animation through spatial reasoning and firs…

Have you seen pelicans in Simon Willison’s tests? It is still not a pelican on bike I would like to publish :) Imho we don’t need to make benchmarks that draw the whole 3D world. Pelican’s drawing is really nice in its simplicity and complexity at the same time. It seems to be an obscene waste of compute time to generate useless 3D worlds that are just a bragging - 3D is really heavy discipline to make it right, see…

At some point, I'd think labs would start "teaching the test" and start adding bike riding pelican's in the fine-tuning.

I also ride a recumbent: Catrike Expedition. I'm not sure I would get the subtleties of the chain guides correct. What's yours? https://www.catrike.com/expedition

Nice!

> We're starting to leave the territory where you'd test an LLM by e.g. "create an svg of pelican on a bicycle". First sentence of the post is clear that it's not solved.

Might be my reading comprehension, but that reads to me like it's implying we're leaving the territory because it's solved and now need something harder.

"Starting to leave" is not the same as "leave" or "left".

When I start to leave my house in the morning, I have not yet gone through the door, but I'm on my way. I walk towards the door to leave the house. I'm leaving the house as I pass through the door. I look back and can see that I've left the house.

Taking a single paragraph of literary text, which is abstract and ambiguous, and converting it into a 3D animation requires an enormous amount of implicit knowledge about spatial relationships, intuitive physics, everyday objects, and so forth. Not to mention the mathematics of 3D transformations and computer graphics more generally. Saying that it's indicative of no more than three.js coding ability is absurd.

Why does it require knowledge about spatial relationships?

See 3D examples from earlier models and how they try to do it but things are stacked on top of the same x/y/z point or mushed together or parented wrong or disconnected.

It’s something that specifically stopped happening in the smarter models.

Same way the “pelican test” became worthless beyond a certain point and just some idea of “I like this one better” not technically more competent in any way.

But why are you starting to leave your house? Likely because you're ready to leave no? To me that's where it was implying that models are ready to leave that benchmark behind, and starting the process is coming up with a new benchmark.

Anyways, if it's just semantic misunderstanding, I have no issue. That means the fact is, models still can't draw a pelican riding a bike? With maybe the exception of Fable 5?

I don't think it's a bad way to benchmark new models, I just find it concerning that the author implies that "pelican on a bicycle" has been exhausted. At the risk of making overly broad, unfalsifiable claims I think multi-year exposure to AI content has dramatically raised our expectations for speed and volume but lowered them for quality. We see a very janky pelican and declare the problem solved.

I worked with an LLM to build a ~3D animation of the Back to the Future delorean Time Machine as a way to spice up the hero on a docs page. That took a fair amount of custom tuning and I had to create a tuning view to get some of the behaviors right. But it was enough fun that I generalized it to take in ~any scene description from a film. It goes out and gets more detailed descriptions and film stills if available b…

Neat app. Would be helpful if I could adjust text size. It's small enough that immediately looked for that setting. I don't think it exists, which means I'm disincentivized from using it. My vision is that of a middle-aged person and I already needed glasses in grade school.

A simple prompt that still stumps frontier LLMs most of the time is “create a pinball game”. They’ll put all the right pieces there but then fail to arrange them such that the game is truly playable. They’ll put a wall in the way of the launch chute so the ball can’t be launched. Or the flippers will pivot the wrong way. Or there will be holes such that the ball drops off the bottom without getting within reach of th…

We don't use these models by way of "one shot" so I don't see why it's relevant. It's clearly useful to let them iterate.

No tool-calling LLM is really "one shot" anymore, so we can easily repurpose that expression to mean "without further human feedback". The generated pinball games still seem to end up coming out broken. There's not much conversation about a good arrangement of pinball playing fields, and the LLM is a next token predictor. Pick any out-of-mainstream topic and same happens. Pelicans on bicycles used to be out-of-mainstream.

> touching the limit of what one can reasonably expect If the expectation is that AI is going to replace "knowledge workers" then the limit would be a darn perfect drawing. We are nowhere close to that. And Elon is already propagating the age of abundance where money won't exist anymore, right before calling the interviewing journalist dishonest and deservedly losing public trust. Smh my head.

> If the expectation is that AI is going to replace "knowledge workers" then the limit would be a darn perfect drawing. We are nowhere close to that. What knowledge workers do you know that have excellent drawing skills? I worked in a design agency and for a couple of years, each week me and a few other people would attempt to sketch a member of our group: one person would be the model and sit still, and everyone els…
