haider1 lays out a striking timeline for OpenAI's new model: RL training reportedly restarted on Aug 28, the model was set to work on Millennium Prize Problems by Sep 1, and a new checkpoint after Sep 3 produced a Navier–Stokes solution — a leap in capability within roughly two weeks of training.
Quoted posts call the model a "newborn" that is already better at math than humans. Note: third-party account, not officially confirmed by OpenAI.
