OpenAI Releases Decisions API in Public Beta, Powered by GPT-6 Luna
OpenAI launched the Decisions API in public beta, powered by GPT-6 Luna. The endpoint delivers typed answers over text and image inputs.
On October 6, 2026, OpenAI officially launched its new Decisions API in public beta, powered by the next-generation GPT-6 Luna model. Designed to streamline decision-making pipelines without complex prompt engineering or custom response parsing, the dedicated endpoint evaluates multimodal text and image inputs to return structured, typed answers to developer-defined questions.

This release focuses directly on common production AI tasks—such as classification, boolean evaluations, content routing, and structured extraction—by handling them as first-class typed operations at the API level.
Decisions API and the Typed Answers Interface
The core capability of the Decisions API is evaluating developer-defined questions against multimodal context to produce reliable, typed outputs.
Compared to coaxing structured JSON schema adherence out of standard conversational chat completion endpoints, the Decisions API provides a streamlined, decision-oriented evaluation workflow.
- Multimodal Context Support: Accepts combined text and image inputs, enabling single-call decisions across visual verification and textual context.
- Developer-Defined Questions: Replaces open-ended generative responses with strictly formatted evaluations tailored to developer-configured schemas.
- Seamless Pipeline Integration: By enforcing typed, predictable outputs, responses connect directly into downstream backend business logic and automated systems without fragile post-processing.
Powered by GPT-6 Luna and Practical Applications
The Decisions API is powered by GPT-6 Luna, part of OpenAI's next-generation model architecture.
Leveraging Luna's optimization for low-latency, deterministic reasoning, the endpoint provides higher reliability for tasks such as automated content moderation, visual inspection workflows, triage routing, and validation gates.
The Decisions API is currently available in public beta. Detailed token pricing tiers, rate limits, and full SDK reference specifications are available via OpenAI's official developer documentation.
