OpenAI Launches Decisions API in Public Beta, Delivering Decisions Up to 10x Faster Through GPT-6 Luna
Summary
OpenAI has launched its Decisions API in public beta on Oct 6, using GPT-6 Luna to deliver decisions up to 10x faster than the Responses API, with outputs spanning Predicates, Choices, and Scores at $0.10 per 1M input tokens—though early tester jefff found rival Jev faster, with a median of 0.3s versus 1.6s per turn.
Key Points
- OpenAI launches the Decisions API in public beta on Oct 6, letting apps choose the right model, tool, or action in near real-time, with decisions up to 10x faster than GPT-6 Luna through the Responses API.
- Powered by GPT-6 Luna, the API accepts text and image inputs and supports 3 kinds of outputs: Predicates to estimate the probability a statement is true, Choices to select from predefined options with confidence scores, and Scores to evaluate inputs against a numeric range.
- Pricing is $0.10 per 1M input tokens with gpt-6-luna, and developers pay only for input tokens with no cache-read, cache-write, or output-token charges; early tester jefff reported Jev was faster (median 0.3s vs 1.6s per turn) and more accurate on nuanced judgment calls in community tests.
