OpenAI's Astra Model Solves 10 Open Math Problems, Disproving Connes' Rigidity Conjecture

GaryMarcus · x · 2026-08-05

OpenAI announced that Astra, its next major model, has solved 10 difficult open math problems, complete with Lean certificates and chain-of-thought walkthroughs.

The results span a wide range of mathematical fields, most notably disproving Connes' Rigidity Conjecture in von Neumann algebras. New bounds were also established for high-dimensional sphere packing, circuit complexity, and graph theory. However, researchers have noted some minor misstatements in OpenAI's official writeup.
