- OpenAI makes the Decisions API generally available for fast bounded choices with GPT-6 Luna
OpenAI made the Decisions API generally available. Built with GPT-6 Luna, it focuses the model on questions with bounded answers so apps can classify, route or score from text, images and structured inputs, which OpenAI says can be up to 10× faster than Luna through the Responses API. Since beta it added GPT-Live integration, prompt caching, US/EU residency, native JSON inputs, images in instructions and up to 400 questions per request. Input is $0.10 per million tokens with no output-token charge.
