Did OpenAI Steal the Navier-Stokes Solution?

NYU mathematician Tristan Buckmaster put out a statement accusing OpenAI of only starting to prompt its model on the Navier-Stokes problem—one of seven Millennium Prize problems carrying a $1 million reward—after word of his own work reached the company. Buckmaster had spent most of the year on the problem with Lev Alantpaj, a mathematician who works at Anthropic, and had been running draft reports through OpenAI's Codex the whole time. When they asked whether the model had been trained on their sessions, they never got a clear answer. Buckmaster also claims OpenAI twice pushed him to drop Alantpaj from the paper because he works for their competitor. He then threatened to go public and was asked, "Why would you ruin your career?" OpenAI's Sebastian Boubeck called all of this "false and inflammatory" and has since apologized for that line, though OpenAI's own write-up confirms its effort only began on September 1st after hearing the rumor the problem was being worked on.

Today's show:

An Anthropic researcher quit this week, saying both leading labs are gambling with everyone's lives. His coworker chimed in and predicts there is a greater than 10% chance that AI will end humanity IN THE NEXT 10 YEARS. Jason and Lon take it to Yohei Nakajima of Untapped Capital, Ben Lerer of Lerer Hippeau, and Rebecca Lynn of Canvas Prime, who cannot decide whether it is the greatest PR strategy in history or some kind of mass psychosis.

Learn why Jason says founders should never hand a frontier lab their proprietary data, whether or not they're offered free credits. PLUS, who really solved Navier-Stokes, and what does the OpenAI–Buckmaster fight mean for anyone doing real work inside ChatGPT or Claude?
