OpenAI launches decisions API in public beta for faster typed responses

OpenAI has launched the Decisions API in public beta, offering a tool that converts text and images into typed answers for code integration. The API is designed to be approximately 10 times faster than the Responses API, with a reported response time of around 150 milliseconds compared to 1.6 seconds for regular Luna calls. The Decisions API uses the gpt-6-luna model, which costs $0.10 per 1M tokens for input, with no output-token charges. It returns structured answers based on predefined questions and types, avoiding prose generation. The API competes with TypeSafe Jev, launched on September 15, 2026, which offers similar functionality at a lower cost. Jev provides input at $0.042 per 1M tokens and supports up to 255 choices, though it remains in early access. OpenAI highlights its edge in handling image inputs, compliance options, and open beta access. The company has not yet published accuracy or calibration data for the Decisions API, advising users to set thresholds using labeled examples from their applications.
