OpenAI previews Decisions API — a Jev-like fast decision model for Luna
At its Dev Day, OpenAI’s CEO Sam Altman revealed the Decisions API, a limited-preview product that lets the Luna model output probabilities over a predefined set of choices (e.g., classifications or agent behaviors) at high speed and low cost. Media and industry observers note the API resembles TypeSafe AI’s recently released Jev; proponents say such decision-focused models could cheaply monitor or gate agentic actions, though exact capabilities and calibration remain unclear.
