OpenAI: GPT-6 Luna Decisions
openai/gpt-6-luna-decisionsdecisionsVision
GPT-6 Luna Decisions is GPT-6 Luna served through OpenAI's Decisions API. Instead of generating text, it reads the content passed as `state` (text, JSON, or images) and returns typed, probabilistic answers to named questions in a single request: the probability of yes for a yes/no question (`noul`), a probability for every option plus the most likely one (`choice`), or a probability for every level of an ordered rubric plus the expected score (`score`).
It is built for classification, routing, moderation, and rubric grading where application code thresholds the returned numbers rather than parsing a chat reply. A request can carry up to 200 questions about the same content.
