Automated excerpt
On 6 October, OpenAI put a public beta of a different answer in front of developers: the Decisions API, a new endpoint — POST /v1/decisions — that returns typed verdicts instead of prose. In public beta the API costs **$0. 10 per million input tokens**, with no output, cache-read or cache-write charges.
