OpenAI previews Decisions API for routing and agent actions

Decisions API lets an application ask a model to pick an answer instead of writing one. In its announcement, OpenAI's OpenAI Developers account said developers define questions and the possible answers, and the API, powered by GPT-6 Luna, makes the decision. OpenAI's examples are classifying content, routing requests and choosing an agent's next action.

Because the developer supplies the possible answers, the result is meant to be one of the application's own options, which its code can act on directly. Sending a request to the right handler or choosing an agent's next step are decisions of that shape, and OpenAI pitches the API as giving apps real-time decision-making for them.

The post leaves the practical details open. Access was a limited preview, and the announcement gives no pricing, speed figures or description of the request format; its attached video had no extractable text and the linked documentation was not available for this explanation. OpenAI's later public beta announcement is covered separately.
