1/ I competed for Team USA at IOI in 2015, so this achievement hits home for me. The biggest highlight: we *did not* train a model specifically for IOI. Our IMO gold model actually set a new state of the art in our internal competitive programming evals. Reasoning generalizes!

@yosupot Hi yosupo, this can be improved to Omega~(N^1.5)? Roughly speaking, pick a random prime p ~ N^0.5 and group the numbers based on residues mod p (each group likely has size ~ N^0.5). Let each group occupy a contiguous subarray. There are only p^2 interesting triples of groups

Evaluating o1 on the International Olympiad of Informatics was very personally meaningful to me. When I competed nine years ago, I never thought I'd be back—so soon—competing with an AI.
To highlight how amazing this model is, we shared on Codeforces its best IOI submissions ⬇️

Major surprise by 3 @Berkeley_EECS grad students: Meghal Gupta, @HongxunWu, Mihir Singhal. *Deterministic* eps-approximate quantiles in O(1/eps) mem. The previous best was the KLL sketch, which was randomized and used O(lglg(1/p)/eps) mem, p = fail prob arxiv.org/abs/2404.03847 1/

❤ Thanks to my advisor @hengjinlp for the supports along the way, and to all authors (@sinongwang, Qifan Wang, @haopeng_nlp, @XiongWenhan, @chenyu_hugo)!
I will be on job market next year, and always excited about deep researches on LLM understanding, adaptation and improvement!
