OpenAI Launches Decisions API in Public Beta, Offering 10x-Faster Structured Decision-Making for Agents

OpenAI has released the Decisions API in public beta, introducing a specialized endpoint that returns typed answers to developer-defined questions rather than generated text, marking a significant shift in how AI agents handle classification, routing, and decision-making tasks. The API, powered by GPT-6 Luna and launched on October 6, 2026, following its announcement at DevDay on September 29, enables developers to structure questions around three core types: predicates that estimate the probability of conditions, choices that select from predefined options, and scores that rate inputs against ordered levels.
