OpenAI's AI beats every human at AtCoder, a top competitive programming contest

This was extremely impressive to me. AtCoder has the hardest problems these days, usually the human onsite final round contestants can't solve more than 2 or 3 problems. This year the problem setter sets the round in a way that maximizes humans chance of winning. Then OpenAI just comes in and solves all problems..

No point for them to even go to IOI or ICPC this year anymore, those are all much easier than this Atcoder contest. And given the mathematical nature of AtCoder problems, not sure if there's any value to do IMO either, except for publicity of course.

At the AtCoder World Tour Finals 2026, an OpenAI system crushed all human competitors in an exhibition match, solving all five problems in the Algorithm Division. Two of those problems were rated exceptionally difficult by observers.
