OpenAI fought dirty on career-making math problem, says NYU mathematician

NYU professor Tristan Buckmaster and Anthropic researcher Levent Alpöge released three proofs that advance the Navier–Stokes existence and smoothness problem, using OpenAI’s Codex alongside Anthropic models. They allege that OpenAI, after learning of their approach, deployed a next-generation model and 300 billion output tokens (≈ $22.5 million) to produce a full proof, prompting a dispute over the timing and source of the breakthrough.
