OpenAI’s Decisions API is now available through AI Gateway at /v1/decisions . It uses the same request and response format as OpenAI, so existing OpenAI SDK integrations can switch by changing the base URL, credentials, and model ID.

Decision models answer typed questions about shared input and return structured answers rather than generated text. In one request, you can ask a model to:

Estimate the probability that a condition is true with a predicate question

Select from supplied options with a choice question

Rate the input against an ordered rubric with a score question

Use these answers for tasks such as classification, routing, triage, and rubric-based scoring.

The endpoint works with any decision model on AI Gateway, including Jev , Liquid d1 , and Laya . Use openai/gpt-6-luna-decisions for OpenAI’s GPT-6 Luna Decisions model.…
