Of the papers submitted to a conference, it might be that reviewers don't offer suggestions that would significantly improve the quality of the work. Indeed the quality of reviews has gone down significantly in recent years. But if Anthropic were going to submit this work to peer review, they would be forced to tighten it up significantly.

The linear probe paper is still written in a format where it could reasonably be submitted, and indeed it was submitted to an ICLR workshop.

peer review would encourage less hand wavy language and more precise claims. They would penalize the authors for bringing up bizarre analogies to physics concepts for seemingly no reason. They would criticize the fact that they spend the whole post talking about features without a concrete definition of a feature.

The sloppiness of the circuits thread blog posts has been very damaging to the health of the field, in my opinion. People first learn about mech interp from these blog posts, and then they adopt a similarly sloppy style in discussion.

Frankly, the whole field currently is just a big circle jerk, and it's hard not to think these blog posts are responsible for that.

I mean do you actually think this kind of slop would be publishable in NeurIPS if they submitted the blog post as it is?

Does it really? If you want an LLM to edit code you need to feed it every single line of code in a prompt. Is it really that surprising that having just learnt it has been timed out, and then seeing code that has an explicit timeout in it, it edits it?? This is just a claim about the underlying foundational LLM since the whole science thing is just a wrapper.

I think this bit of it is just a gimmick put in for hype purposes.

I agree with you that transformers are probably not the architecture of choice. Not sure what that has to do with the viability of RL though.

Hmm well the reason a pre-trained transformer is a fancy sentence completion engine is because that is what it is trained on, cross entropy loss on next token prediction. As I say, if you train an LLM to do math proofs, it learns to solve 4 out of the 6 IMO problems. I feel like you're not appreciating how impressive that is. And that is only possible because of the RL aspect of the system.

To be clear, i'm not claiming that you take an LLM and do some RL on it and suddenly it can do particular tasks. I'm saying that if you train it from scratch using RL it will be able to do certain well defined formal tasks.

Idk what you mean about the online learning ability tbh. The paper uses it in the exact way you specify, which is that it uses RL to play montezuma's revenge and gets better on the fly.

Similar to my point about the inference time RL ability of the alphaProof LLM. That's why I emphasized that RL is done at inference time, like each proof you do it uses to make itself better for next time.

I think you are taking LLM to mean GPT style models, and I am taking LLM to mean transformers which output text, and they can be trained to do any variety of things.

But RL algorithms do implement things like curiosity to drive exploration?? https://arxiv.org/pdf/1810.12894.

Thinking to arbitrary depth sounds like Monte Carlo tree search? Which is often implemented in conjunction with RL. And working memory I think is a matter of the architecture you use in conjunction with RL, agree that transformers aren't very helpful for this.

I think what you call 'trial and error', is what I intuitively think of RL as doing.

AlphaProof runs an RL algorithm during training, AND at inference time. When given an olympiad problem, it generates many variations on that problem, tries to solve them, and then uses RL to effectively finetune itself on the particular problem currently being solved. Note again that this process is done at inference time, not just training.

And AlphaProof uses an LLM to generate the Lean proofs, and uses RL to train this LLM. So it kinda strikes me as a type error to say that DeepMind have somehow abandoned RL in favour of LLMs? Note this Demis tweet https://x.com/demishassabis/status/1816596568398545149 where it seems like he is saying that they are going to combine some of this RL stuff with the main gemini models.

The distinction is that LLMs are not used for what they are trained for in this case. In the vast majority of cases someone using an LLM is not interested in what some mixture of openai employees ratings + average person would say about a topic, they are interested in the correct answer.

When I ask chatgpt for code I don't want them to imitate humans, I want them to be better than humans. My reward function should then be code that actually works, not code that is similar to humans.

How about you want to solve sudoku say.And you simply specify that you want the output to have unique numbers in each row, unique numbers in each column, and no unique number in any 3x3 grid.

I feel like this is a very different type of programming, even if in some cases it would wind up being the same thing.

I did read your entire comment, and that is what prompted my response, because from my perspective your entire premise was based on LLMs failing at simple examples, and yet despite admitting you thought there was a chance an LLM would succeed at your example, it didn't seem you'd bothered to check.

The argument you are making is based on the fact that the example is simple. If the example were not simple, you would not be able to use it to dismiss LLMs.

I am not surprised that GPT 3.5 and 4o failed, they are both terrible models. GPT4-o is multimodal, but it is far buggier than gpt-4. I tried with claude 3.5 sonnet and it got it first try. It also was able to compute the moves when told the rule change.

To be clear, the construction given here violates the finite additivity property of measure. It's got nothing to do with the countable/uncountable additivity property.

Essentially the difficulty arises from attempting to assign a measure (area) to every single subset of the sphere, where you say that rotations need to preserve this measure. The paradox can be viewed as a proof that you cannot assign a measure to every subset of the sphere in a consistent way.

The way measure theory resolves this is by showing that if you restrict to appropriate subsets, called measurable subsets, you can get all the nice properties you would expect.

It turns out that basically everything is measurable. In fact the existence of a non-measurable set is independent of ZF. This means that you need the axiom of choice, which was used here in the Banach-Tarski paradox, in order to construct a non-measurable set. So measure theory doesn't really lose a great deal by restricting in this way, which is why it gives such a great theory of integration.

I don't see how the point about the typical human is relevant. Either you can reason or you can't, the ARC test is supposed to be an objective way to measure this. Clearly a vanilla LLM currently cannot do this, and somehow an expert crafting a super-specific prompt is supposed to be impressive.

The curious thing is if you can ever hit a snowball type point, because by proving theorems you are generating training data, and maybe you can get to a point where you effectively have limitless data.

GPT-4o 2 years ago

Doubtful. Apple can get away with tiny iterations on smartphones because they have the brand and they know people will always buy their latest product. LLMs aren't physical products so there is no cost to switching other than increased API cost, meaning openAI won't be able to recoup the cost of training a new model unless the model is sufficiently different that it justifies people paying significantly more for.

The special thing about GPT-4o is the multimodal capabilities, all the metrics suggest that it is the same size language model roughly as GPT-4. The fact it's available for free also points to it not being the most intelligent model that openAI has atm.

The time to evaluate whether we're starting to level off is when they've trained a model 10x larger than gpt-4 and we don't see significant change.
