GoKawiilOpenAI launches Decisions API in public beta with gpt-6-luna model
OpenAI has released a public beta of a new Decisions API that evaluates text and images and returns typed answers—probabilities, choices, or scores—about 10x faster than its Responses API. The endpoint, POST /v1/decisions, currently supports only the gpt-6-luna model, and requests combine a model, shared input evidence, and a set of named questions. OpenAI says general availability is expected in the coming weeks.
GoKawiil's interpretation of the reporting above, not reported fact.
By returning structured, typed outputs rather than free-form text, the API could simplify building classification, routing, and prioritization logic directly into applications without extra parsing. The speed claim suggests OpenAI is positioning this as infrastructure for high-volume, latency-sensitive decision tasks rather than open-ended generation. Limiting the beta to a single model suggests OpenAI is still validating performance before broader model support and general availability.
- Decisions API is in public beta via POST /v1/decisions, with GA expected soon.
- It returns predicate (probability), choice, or score answers instead of open-ended text.
- Only the gpt-6-luna model is currently supported, and OpenAI claims 10x faster responses than the Responses API.
