OpenAI makes the Decisions API generally available
OpenAI’s 22 October release notes confirm that the Decisions API has moved out of public beta. Developers can use gpt-6-luna to evaluate evidence and return a category, probability or score. The release adds structured JSON input, images in individual question instructions and prompt caching. The maximum number of questions per request has increased from 200 to 400.
Access and cost: this is an API for software integration. OpenAI’s implementation guide lists uncached input at US$0.10 per million tokens, with no charge for output tokens on this endpoint. Cache reads are discounted, cache writes are charged, and regional-processing premiums and long-context multipliers can apply. These endpoint-specific terms should not be assumed to cover other GPT-6 Luna requests.
Tecrave analysis: a service firm’s developer could use it to sort incoming enquiries into billing, technical support and other queues. Test it against previously labelled examples and keep uncertain cases in a human review queue before connecting any consequential action.
Useful caveat: a category is a model judgement, not a verified fact. The API returns answers; your application executes any resulting action. Integration, monitoring and mistake handling still need an owner. If a simple form rule already routes enquiries reliably, there may be little reason to add AI.
