On the record
OpenAI says it resolved Navier-Stokes. Buckmaster says Bubeck wanted his co-author removed.
You can read the three first-party accounts of the Navier-Stokes announcement side by side here: OpenAI's page, Buckmaster's four-page signed statement and Alpöge's post. They agree on the order of events and split in three places. If you are weighing OpenAI's frontier claims, the practical point is that the result was produced by an internal model no one outside the company can use, and that the mathematician it was described to says he has not read the proof.
