Source of truthdevelopers.openai.com/api/docs/changelogAccording to OpenAI's developer changelog, the Decisions API became generally available with gpt-6-luna on October 22, after the beta released on October 6. Each request now supports up to 400 questions, up from 200, individual question instructions can include images, and structured data can be passed directly with input_json. OpenAI says the API turns text and images into typed answers 10x faster than the Responses API.
