OpenAI Releases Decisions API in Public Beta, Powered by GPT-6 Luna

OpenAI has launched the Decisions API in public beta, a new interface powered by GPT-6 Luna designed to enable zero-shot decision-making and calibration in production systems. This represents a significant new agentic capability, allowing developers to integrate structured decision logic directly into their applications without training custom classifiers or building complex prompt chains. The API exposes probabilistic decision outputs with calibration signals, making it particularly useful for risk-sensitive workflows like content moderation, routing, and automated triage. Developers building agentic pipelines can now delegate discrete decision nodes to the API rather than relying on general-purpose chat completions. Public beta access means production use is now feasible with appropriate rate limits and SLA expectations.
