OpenAI Decisions API Hits Public Beta With 10x Faster Typed Answers

OpenAI has launched its Decisions API in public beta, turning text and images into typed answers such as probabilities, choices and scores instead of prose. It runs on the gpt-6-luna model with a 1,050,000-token context window and is claimed to be about 10x faster than the Responses API. Input costs $0.10 per 1M tokens with no output charges.

• POST /v1/decisions returns probabilities, choices and scores, not prose
• OpenAI claims ~10x faster than the Responses API, with decisions near 150 ms
• Only gpt-6-luna is supported, with a 1,050,000-token context window
• Input costs $0.10 per 1M tokens; output and cache are free
