From that thread: "The model solved P1 through P5; it did not produce a solution for P6." It's interesting that it didn't solve the problem that was by far the hardest for humans too. China, the #1 team got only 21/42 points on it. In most other teams nobody solved it.
To me, this is a tell of human-involvement in the model solution. There is no reason why machines would do badly on exactly the problem which humans do badly as well - without humans prodding the machine towards a solution. Also, there is no reason why machines could not produce a partial or wrong answer to problem 6 which seems like survivor bias to me. ie, that only correct solutions were cherrypicked.

What's the clear path to improved efficiency now that we've reached peak data?
A) that's not clear
B) now we have "reasoning" models that can be used to analyse the data, create n rollouts for each data piece, and "argue" for / against / neutral on every piece of data going into the model. Imagine having every page of a "short story book" + 10 best "how to write" books, and do n x n on them. Huge compute, but basically infinite data as well.
We went from "a bunch of data" to "even more data" to "basically everything we got" to "ok, maybe use a previous model to sort through everything we got and only keep quality data" to "ok, maybe we can augment some data with synthetic datasets from tools etc" to "RL goes brrr" to (point B from above) "let's mix the data with quality sources on best practices".

#353Earlier quoted context omitted.
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%,…
The correctness of 8%, 16%, and 90% are all equally unknown since we only have one timeline, no?

#354Google also joined IMO, and got gold prize. https://x.com/natolambert/status/1946569475396120653 OAI announced early, probably we will hear announcement from Google soon.
Google’s AlphaProof, which got a silver last year, has been using a neural symbolic approach. This gold from OpenAI was pure LLM. We’ll have to see what Google announces, but the LLM approach is interesting because it will likely generalize to all kinds of reasoning problems, not just mathematical proofs.
The key difference is that they claim to have not used any verifiers.

#355Some 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...

Unless the machine is trained to mimic human thought process.

Off topic, but am I the only one getting triggered every time I see a rationalist quantify their prediction of the future with single digit accuracy? It's like their magic way of trying to get everyone to forget that they reached their conclusion in completely hand-wavy way, just like every other human being. But instead of saying "low confidence" or "high confidence" like the rest of us normies, they will tell you t…

#359Interesting that the proofs seem to use a limited vocabulary: https://github.com/aw31/openai-imo-2025-proofs/blob/main/pro... Why waste time say lot word when few word do trick :) Also worth pointing out that Alex Wei is himself a gold medalist at IOI.
Terence Tao also called it, that the top LLMs would get gold this year in a recent podcast.
