Highlights

  • Published September 30, 2026 after Sam Altman described finite-choice decisions on Luna at DevDay.
  • Frames decision models as a cheaper watcher layer than frontier chat models for agent safety loops.
  • Notes limited-preview access and sparse third-party benchmarks at publication time.

Watch out

News analysis, not a reproducible eval; OpenAI pricing and response schema were still undisclosed.
