> high school/early university maths problems should not have been a stretch at all for it.

Either you are unfamiliar with the International Math Olympiad or you’re trying to be misleading.

Calling these problems high school/early university maths is a ridiculous characterization.

Some previous predictions: In 2021 Paul Christiano wrote he would update from 30% to "50% chance of hard takeoff" if we saw an IMO gold by 2025. He thought there was an 8% chance of this happening. Eliezer Yudkowsky said "at least 16%". Source: https://www.lesswrong.com/posts/sWLLdG6DWJEy3CH7n/imo-challe...

While I usually enjoy seeing these discussions, I think they are really pushing the usefulness of bayesian statistics. If one dude says the chance for an outcome is 8% and another says it's 16% and the outcome does occur, they were both pretty wrong, even though it might seem like the one who guessed a few % higher might have had a better belief system. Now if one of them had said 90% while the other said 8% or 16%,…

From a mathematical point of view there are two factors: (1) Initial prior capability of prediction from the human agents and (2) Acceleration in the predicted event. Now we examine the result under such a model and conclude that:

The more prior predictive power of human agents imply the more a posterior acceleration of progress in LLMs (math capability).

Here we are supposing that the increase in training data is not the main explanatory factor.

This example is the gem of a general framework for assessing acceleration in LLM progress, and I think its application to many data points could give us valuable information.

Wow. That's an impressive result, but how did they do it? Wei references scaling up test-time compute, so I have to assume they threw a boatload of money at this. I've heard talk of running models in parallel and comparing results - if OpenAI ran this 10000 times in parallel and cherry-picked the best one, this is a lot less exciting. If this is legit, then we need to know what tools were used and how the model used…

Why is that less exciting? A machine competing in an unconstrained natural language difficult math contest and coming out on top by any means is breath taking science fiction a few years ago - now it’s not exciting? Regardless of the tools for verification or even solvers - why is the goal post moving so fast? There is no bonus for “purity of essence” and using only neural networks. We live in an era where it’s hard…

>> Why is that less exciting? A machine competing in an unconstrained natural language difficult math contest and coming out on top by any means is breath taking science fiction a few years ago - now it’s not exciting?

Half the internet is convinced that LLMs are a big data cheating machine and if they're right then, yes, boldly cheating where nobody has cheated before is not that exciting.

In fact no car company claims “gold medal” performance in Olympic running even they can do that 100 yeas ago. Obviously since IMO does not generate much money so it is an easy target. BTW; “Gold medal performance “ looks a promotional term for me.

Glock should show up to the UFC and win the whole tournament handily.

These are high school level only in the sense of assumed background knowledge, they are extremely difficult. Professional mathematicians would not get this level of performance, unless they have a background in IMO themselves. This doesn’t mean that the model is better than them in math, just that mathematicians specialize in extending the frontier of math. The answers are not in the training data. This is not a mode…

>> This is not a model specialized to IMO problems.

How do you know?

I encourage anyone who thinks these are easy high-school problems to try to solve some. They're published (including this year's) at https://www.imo-official.org/problems.aspx . They make my head spin.

I didn't know there were localized versions of the IMO problems. But now that I think of it, having versions of multiple languages is a must to remove the language barrier from the competitors. I guess having that many language versions (I see ~50 languages?) may make keeping the security of the problems considerably harder?

I thought progress might be slowing down, but this is clear evidence to the contrary. Not the result itself, but the claims that it is a fully general model and has a clear path to improved efficiency.

I feel like I've noticed you you making the same comment 12 places in this thread -- incorrectly misrepresenting the difficulty of this tournament and ultimately it comes across as a bitter ex. Here's an example problem 5: Let a1,a2,…,an be distinct positive integers and let M=max⁡1≤i Find the maximum number of pairs (i,j) with 1≤i<j≤n for which (ai +aj )(aj −ai )=M.

Where did you get this? Don't see it on the 2025 problem set and now I wanna see if I have the right answer

- AI competing is "wholly unfair" - "[AI is] far away from being substantially being better than MCTs" ^ pick only one

Yeah it’s a completely fair playing field, it’s completely obvious that AI should be able to compete with humans in the same way that robotics and computers can compete with humanity (and are better suited for many tasks).

Whether or not they’re far away from being better than humans is up to debate, but the entire point of these types of benchmarks it to compare them to humans.

> I think OpenAI participating is nothing but a publicity stunt and wholly unfair and disrespectful against Human participants. It should be allowed for AI models to participate, but it should not be ranked equally,

OpenAI did not participate in the actual competition nor were they taking spots away from humans. OpenAI just gave the problems to their AI under the same time limit and conditions (no external tool use)

> nor put any engineers under duress of having to pull all-nighters.

Under duress? At a company like this, all of the people working on this project are there because they want to be and they’re compensated millions.
