OpenAI's Decisions API lands on AI Gateway: swap the base URL and model ID to ask for probabilities, choices and scores
OpenAI's Decisions API is now callable through AI Gateway at /v1/decisions, using 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, supporting predicate, choice and score questions 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; OpenAI's GPT-6 Luna Decisions is reached as openai/gpt-6-luna-decisions, separate from the text-generating openai/gpt-6-luna.
