A math professor says OpenAI threatened his career

The credit fight over the Navier-Stokes breakthrough now has quotes on the record, and they are ugly.

What Buckmaster alleges

NYU professor Tristan Buckmaster published a statement describing what happened behind the scenes. He says OpenAI researcher Sebastien Bubeck twice pushed him to drop his co-author Levent Alpoge from their Navier-Stokes paper, because Alpoge works at Anthropic.

When Buckmaster refused and said he would go public, he says the answer was “Why would you ruin your career?” followed by “If you don’t want me to be nice, then I don’t have to be nice.”

What OpenAI concedes

OpenAI responded publicly on September 8. The company admitted it cannot rule out that de-identified data from the pair’s use of its products helped improve its models. Bubeck rejects the allegations as false and inflammatory.

Why the statement matters

Credit disputes in mathematics are usually fought quietly, in journals and letters. This one now includes a tenured professor at one of the strongest math departments in the United States putting direct quotes on the record against a frontier lab, and the lab conceding uncertainty about whether its models benefited from the researchers’ own usage data. The open question is whether any independent process can establish what OpenAI’s systems learned from whom, and when.
