OpenAI launches Decisions API: typed verdicts without generated text

OpenAI has released its Decisions API in public beta, returning typed results instead of text: a probability, a choice from a defined list, or a score against a rubric. Pricing is $0.10 per 1M input tokens with no output charges. It is beta-only with a single model, gpt-6-luna, and no published benchmark for the claimed 10x speedup.
