Decisions API (Public Beta)

OpenAI's endpoint for fast yes/no, multiple-choice, and scored answers about text and images is now open to all developers.

Returns three answer types: the probability a statement is true, a pick from options you define with confidence scores, or a score on a numeric scale
Runs on GPT-6 Luna through its own endpoint and answers up to 10x faster than the Responses API
Handles up to 10 independent questions in one request; questions that depend on each other need separate requests
Accepts text and images, with images sent inline rather than by link
Costs $0.10 per 1M input tokens, with no charge for output or caching
Was in limited preview before this; OpenAI expects general availability in the coming weeks

Sorting, routing, and scoring high volumes of inputs, like tagging support tickets or flagging off-brand product images.

You need a quick, structured answer to a fixed question, not a written response.

Developers building routing, moderation, or triage into marketing and support tools.

Staying informed is great. Staying ahead is better.
