Mathematician alleges OpenAI's Navier-Stokes proof followed his work; Bubeck calls claims false

eyishazyer · x · 2026-09-08

Tristan Buckmaster (NYU) and Levent Alpöge (Anthropic) spent a year on Euler, Boussinesq and Navier-Stokes variants, using Claude and Codex to generate candidate proofs verified by hand and checked in Lean, with Terence Tao praising the advance. Buckmaster alleges OpenAI then told him its internal model produced a 100-page blow-up proof for forced Navier-Stokes via the same narrow technical route, with its first prompt coming only after news of his work reached them — and that OpenAI never clarified whether the model trained on his Codex sessions, and proposed dropping Alpöge as coauthor because he works at Anthropic. Bubeck called the allegations "false and inflammatory"; Noam Brown backed him, while Anthropic's Sholto Douglas shared a year-old email showing Alpöge contacted Buckmaster about this exact problem in September 2025. If the timeline holds, OpenAI got there knowing where to look, not first.
