OpenAI's internal model 'Bel' reportedly produced a ~100-page Navier-Stokes proof

Mathematician Tristan Buckmaster says he was told that OpenAI's internal model 'Bel' solved the forced case of the Navier-Stokes equations — the case covered by Clay's Millennium Prize problem — producing a roughly 100-page proof. He has not yet seen the proof. If verified, it would be a landmark AI-for-math breakthrough, but it remains unverified and unreviewed.
