OpenAI says its Decisions API is in public beta, offering typed outputs for classification, routing and scoring across text and images.
OpenAI said on Oct. 22, 2026, that its Decisions API is designed to provide “fast, focused, low-cost decisions” for applications, with the service described in documentation as a public beta. The company’s materials position the API as a way to return typed decisions rather than open-ended prose, a distinction that matters for use cases such as classification, routing and prioritization.
According to OpenAI’s developer documentation verified on Oct. 22, 2026, the Decisions API uses gpt-6-luna through POST /v1/decisions and can evaluate text and images. The documentation says it can produce three main kinds of outputs: predicates, which estimate whether a condition is true; choices, which select among predefined options; and scores, which assess inputs against a rubric. Those functions are framed for application tasks including classification, request routing and prioritization.
OpenAI also claims the API can provide answers roughly 10 times faster than the Responses API, but that figure is a vendor claim and is not independently verified in the supplied material. The same documentation recommends calibrating decision thresholds against labeled application examples and weighing the costs of false positives and false negatives when deploying the system.
The developer materials further say eligible customers can use Zero Data Retention and HIPAA-supported configurations, while data residency and regional processing are supported in the United States and Europe, subject to eligibility requirements and limitations. Separate recent notices in the supplied material indicate the Decisions API was available in Public Beta on Oct.
