Unverified rumor claims OpenAI's internal model 'Bel' solved Navier–Stokes with 10,000 agents

An X user claims OpenAI has an internal model codenamed "Bel," reportedly far more capable than the rumored "Astra": allegedly 10,000 agents running 88 hours solved the Navier–Stokes problem, with rumors both OpenAI and Anthropic may have cracked another Millennium Prize Problem.

The poster frames this as a "country of geniuses in a data center" and evidence of recursive self-improvement, speculating Bel could aid cancer research or even room-temperature superconductors, and that its successor could be superintelligent.

Caveat: all of this is unverified speculation from a non-authoritative source; no official evidence confirms Astra or Bel exist.
