GPT-6 Luna Decisions

by OpenAI

GPT-6 Luna Decisions is the version of OpenAI's GPT-6 Luna that answers through OpenAI's Decisions API. It makes judgments for software to act on instead of writing text for a person to read: you send an input (a string, or user messages that mix text and images) with a list of questions, and every question comes back as a typed answer with probabilities. A predicate question returns the probability that a statement about the input is true. A choice question picks one of 2 to 255 options you define and returns a probability for each. A score question places the input on your own ordered scale of 2 to 10 levels and returns the probability of every level and a probability-weighted score. Choice and score answers also carry a confidence value, answers come back in question order, and a choice can only be one of the options supplied. It suits classification, routing, guardrail checks and rubric scoring where the result feeds code, with the probability deciding what runs automatically and what goes to a person or a larger model. Because it reads images directly, the same questions work on screenshots, scanned documents and photos. Opper also serves it in TypeSafe's System One format, so code written for Jev or Clef can switch to it by changing the model name; that path takes text only. OpenAI documents the API at https://developers.openai.com/api/docs/guides/decisions.
