The biggest story in AI was released a few weeks ago but was given little attention: on the recent USAMO, SOTA models scored on average 5% (IIRC, it was some abysmal number). This is despite them supposedly having gotten 50%, 60% etc performance on IMO questions. This massively suggests AI models simply remember the past results, instead of actually solving these questions. I'm incredibly surprised no one mentions this, but it's ridiculous that these companies never tell us what (if any) efforts have been made to remove test data (IMO, ICPC, etc) from train data.

Yeah I’m a computational biology researcher. I’m working on a novel machine learning approach to inferring cellular behavior. I’m currently stumped why my algorithm won’t converge.

So, I describe the mathematics to ChatGPT-o3-mini-high to try to help reason about what’s going on. It was almost completely useless. Like blog-slop “intro to ML” solutions and ideas. It ignores all the mathematical context, and zeros in on “doesn’t converge” and suggests that I lower the learning rate. Like, no shit I tried that three weeks ago. No amount of cajoling can get it to meaningfully “reason” about the problem, because it hasn’t seen the problem before. The closest point in latent space is apparently a thousand identical Medium articles about Adam, so I get the statistical average of those.

I can’t stress how frustrating this is, especially with people like Terence Tao saying that these models are like a mediocre grad student. I would really love to have a mediocre (in Terry’s eyes) grad student looking at this, but I can’t seem to elicit that. Instead I get low tier ML blogspam author.

**PS** if anyone read this far (doubtful) and knows about density estimation and wants to help my email is bglazer1@gmail.com

I promise its a fun mathematical puzzle and the biology is pretty wild too

It's funny, I have the same problem all the time with typical day to day programming roadblocks that these models are supposed to excel at. I'm talking about any type of bug or unexpected behavior that requires even 5 minutes of deeper analysis.

Sometimes when I'm anxious just to get on with my original task, I'll paste the code and output/errors into the LLM and iterate over its solutions, but the experience is like rolling dice, cycling through possible solutions without any kind of deductive analysis that might bring it gradually closer to a solution. If I keep asking, it eventually just starts cycling through variants of previous answers with solutions that contradict the established logic of the error/output feedback up to this point.

Not to say that the LLMs aren't productive tools, but they're more like calculators of language than agents that reason.

This might be honing in on both the issue and the actual value of LLM:s. I think there's a lot of value in a "language calculator" but if it's continuously being sold as something it's not we will dismiss it or build heaps of useless apps that will just form a market bubble. I think the value is there but it's different from how we think about it.
