OpenAI solves 90 of top 500 open math problems at ~3 hours Pro compute each
TheZvi · x · 2026-10-08
Zvi's weekly AI #189: the biggest drop wasn't a new model but "the biggest day in the history of mathematics" — OpenAI published solutions to 90 of the top 500 open math problems (plus others) at an average of 3 hours of Pro-level compute per question. Also covered: Claude Haiku 5.5 at $0.10/$0.50 looks promising; his write-up of The Curve conference (Chatham House); and new posts on model welfare for Mythos/Fable 5.1 and Opus 5.5, which he argues matters for understanding today's AIs regardless of one's stance.
