Unverified rumor circulating: if leaker Leo's info is right, OpenAI will first ship Astra, then a new pre-training run called Fable meant to dethrone it — and it already has an internal model more capable than GPT-6 Astra, which supposedly produced a Navier–Stokes problem solution.

A replier is skeptical, calling it obvious that frontier labs keep stronger internal models. Treat as unconfirmed speculation.
