Details

OpenAI has released a limited preview of the Decisions API, built on GPT-6 Luna. Developers define a question and possible answers, and the API returns the optimal choice based on the provided context.

This API can be used for various scenarios, such as content classification, request routing, and selecting an agent's next action. Both text and images can be input as context; for example, providing a customer support request and a list of responsible teams will return the appropriate team selection.

Testing is currently underway with selected API customers. OpenAI stated that it plans to broaden access within the next few days, though this is distinct from a confirmed general availability status.
