OpenAI Says AI Solved Navier–Stokes Millennium Prize Problem

According to Axios, OpenAI said Tuesday that an internal model it described as significantly more capable than GPT-6 Astra produced a proof that the three-dimensional Navier–Stokes equations can develop a singularity in finite time. The company said the effort began Sept. 1 after researchers heard rumors that two Millennium Prize problems had been solved, and that roughly 10,000 concurrent agents reached the result in about 88 hours. OpenAI executives said the project used enormous computing power and cost in the millions of dollars. The announcement was shadowed by questions from NYU mathematician Tristan Buckmaster and Anthropic researcher Levent Alpöge, who had been working on closely related fluid-dynamics research. Buckmaster has publicly questioned whether OpenAI moved down a research path it learned about from their work and raised concerns about whether private Codex material could have played a role. OpenAI said neither its researchers nor its agents saw Buckmaster and Alpöge's work before it was released publicly. Chief research officer Mark Chen said no people or AI systems searched through user data to solve the problem. OpenAI said it does not intend to claim the $1 million Millennium Prize.
