Mathematician Tristan Buckmaster alleges OpenAI pursued Navier–Stokes breakthrough after learning of his work; Terence Tao calls his and Alpöge's proof a 'remarkable achievement'

Mathematician Tristan Buckmaster claims OpenAI pursued a breakthrough on the Navier-Stokes equations after learning of his work with Levent Alpöge. Fields Medalist Terence Tao praised their proof as a 'remarkable achievement,' while Buckmaster raises concerns about OpenAI's methods and potential use of his unpublished drafts.

Mathematician Tristan Buckmaster has raised serious allegations against OpenAI, claiming the company pursued a breakthrough on the Navier-Stokes equations after learning about his work with Levent Alpöge. Buckmaster's concerns stem from a conversation with OpenAI's Sébastien Bubeck, where he was informed that an internal model had produced a proof of the Navier-Stokes problem shortly after OpenAI became aware of his research.12310

Buckmaster stated, “When I heard ‘forced,’ it was a bright red flag,” indicating that the approach OpenAI described closely mirrored his and Alpöge's work. He also expressed doubts about whether OpenAI's model had been trained on his unpublished drafts, which he had been inputting into the company's tools.

In contrast, Fields Medalist Terence Tao praised Buckmaster and Alpöge's work as a “remarkable achievement,” noting that their proof has been formalized in Lean, ensuring its logical integrity. Tao emphasized that while the methods show promise for extending to the Navier-Stokes problem, he does not declare it solved yet.6

The Navier-Stokes equations, a fundamental question in fluid dynamics, remain one of the seven Millennium Prize Problems, with a $1 million prize for a complete solution. Buckmaster's allegations raise ethical questions about the intersection of AI and academic research, particularly regarding the ownership and originality of mathematical breakthroughs.

OpenAI's alleged proof, reportedly generated in just a few days, remains undisclosed, leaving the mathematical community unable to verify its claims. Buckmaster's decision to publish his findings publicly, despite their unfinished state, aims to establish a timeline for his research amidst these controversies.

Key Insight
“Buckmaster says OpenAI's model was first used on easier problems, including Euler, before turning to Navier–Stokes, and that an 'insane amount of compute' was used. He also alleges OpenAI asked him to remove Alpöge because he works at Anthropic, a rival AI company.”

“Fields Medalist Terence Tao — widely regarded as one of the best living mathematicians — has weighed in on the fluid dynamics results published today by NYU’s Tristan Buckmaster and Anthropic’s Levent Alpöge, calling the work a “remarkable achievement” and saying he sees no obvious obstacle to the same methods eventually being pushed all the way to Navier-Stokes, one of math’s seven Millennium Prize Problems.”

“OpenAI appears to have made a major claim about one of mathematics’ most famous unsolved problems, saying its reasoning AI generated a proof for the Navier-Stokes equations. But the proof remains private, while mathematicians involved in related research have questioned how OpenAI arrived at its result.”
