>> NOT an LLM. its a small ar transforme Super cool project! Though, aren't most modern LLM's ar transformers internally?

Not all transformers are _language_ models - the sequences of tokens don't have to be sequences of words.

Isn't this cheating? Or rather, are frontier agents only looking at one question at a time? If I understand correctly, you're looking at all the examples of the exam questions. If the exam was adjusted so that you can only look at one question at a time, you won't get 44% anymore.

Why would that be cheating? That's what humans do when they learn, they look for the signals and patterns that reduce the possible set of answers so they can converge on the solution and narrow the search space.

"I don’t understand why others didn’t figure this out" - how about we allot the possibility that so many of presumed ML experts don't have any clue what they be doing, and are eventually API bitches, nothing more.

Could be that many presumed ML experts don't even know how to train on the evaluation set

I don’t have any kind of ML background but I have always thought of sample efficiency as the great unsolved problem of AI. We humans have unbelievably good sample efficiency; often we can durably learn something on just a single example or two. This is the main area in which LLMs are vastly, vastly behind us.

No, the unsolved problem of AI is continuous learning. We never stop learning, we don't have a "training phase". You are always updating your world model even when you sleep. Also more quality training data does lead to greater learning efficiency as you have more priors to work with.

I think(?) you’ve already probably done a good job of explaining this criticism for semi-informed people. But can you dumb it down even more for those of us who are almost entirely out-of-the-loop? > Training on the eval puzzles is cheating / “training on test” > No this is false. “Training on test” specifically means training on the labels of test data. The labels were not trained on. > Also, ARC is a metalearning b…

I won't weigh in on whether it's "cheating" but it is definitely benchmaxxing

Yeah, unless the model is evaluated with blind hold outs, the benchmarks are misleading.

> I agree that its rare to see to face problem sets in real life where every problem is given at once. Even if it is (like an exam), humans can usually only attempt one at a time

Just one small snippet that I thought was interesting. I would always read through ~the entire exam before starting. Both so that I could find the problems most approachable to me, but also because sometimes it helps me figure out the rest of the questions :-)

> Ban offline training/pretraining. Models must train from scratch after submission Previously this was considered impossible so rule. My model shows this is possible Guarantees no synthetic data can be used It makes the comparison fair across differet models. Otherwise some models like LLMs can benchmaxx ARC by using ungodly amounts of offline training. (Since the benchmark has been around a long time, many ARC-like datasets have been created)

I'm not an ML researcher, so YMMV, but... how could a model learn to answer these ARC-AGI questions without training beforehand?

Hi! Author here. Surprised to see this on HN now. Happy to answer any questions! Some context about this: - This is NOT an LLM. its a small ar transformer trained from scratch. One of the points was that extremely complex problems can be tackled without LLMs - Till the v1 of this result, this benchmark was only scaled by LLMs or their finetunes (ofc w enormous training costs). Other attempts performed okayish but use…

>Personally I think today's frontier models can be beat by training from scratch

You mean for a specific usecase?

Also aren't frontier models trained 'from scratch'?

> Increases in LLM scores are now mainly driven by post training (evidence in next section) and are probably a function of amount of synthetic data. They are learning to solve ARC tasks, not learn general abstract reasoning Agreed and that's for any benchmark. Private tests are better but you still have to trust the provider to not log and use them for training. That's why I like when a new set of tests like a new AR…

> The "67 cents" part though is misleading imho. You can't extrapolate from there and think that investing say $100 will get you a lot better results.

Nothing about saying that it cost 67 cents implies that it will. Knowing only that it costs 67 cents you also have no reasonable basis for extrapolation. It doesn't indicate a trend whatsoever.
