OpenAI may have cracked a hardest math problem, with Claude and Codex drafting proofs

eyishazyer · x · 2026-09-08

OpenAI may have solved one of math's hardest fluid dynamics problems, though the journey was messy. NYU mathematician Tristan Buckmaster and Anthropic researcher Levent Alpöge spent a year working on the Euler, Boussinesq, and a variant of the Navier-Stokes equations, using AI heavily—Claude and Codex—to generate candidate proofs that they then verified and rewrote by hand. The post is a retelling and the linked source details are truncated.
