OpenAI's Decisions API is generally available on gpt-6-luna, with up to 400 questions per request and prompt caching for shared input
The dedicated endpoint for turning text and images into typed answers leaves beta. What the GA version adds over the beta.
// Key points
- The Decisions API (v1/decisions) is generally available with gpt-6-luna. When the beta shipped on October 6, OpenAI said it turns text and images into typed answers 10x faster than the Responses API.
- Each request now supports up to 400 questions, up from 200 in the beta.
- Shared input can hit the prompt cache across requests for cache discounts, individual question instructions can include images, and structured data can be passed directly with input_json.
Builder's takeThe docs list uncached input on gpt-6-luna at $0.10 per million tokens with output not charged, which is cheap for read-this-then-answer-a-list-of-questions work. Tagging a résumé with a dozen labels in AI Interview has exactly that shape: put the résumé in shared input to hit the cache, make each label a question, and compare cost and latency against today's general-purpose call.
