The Decisions API is an OpenAI tool that turns complex text or image analysis into simple, fast yes/no or multiple-choice answers instead of long written responses.

The Decisions API is a product from OpenAI that uses artificial intelligence to look at text, images, or other input and return a short, structured answer rather than a paragraph of writing. Instead of generating prose, it returns probabilities, choices, and scores. This makes it easier for software to read the result and take action based on it.
Most AI tools output long-form text that needs to be parsed before a program can use it. The Decisions API skips that step. It gives apps simple answers in milliseconds, letting them branch their logic — if this, then that — without waiting for a full written response. It is designed especially for tasks that boil down to a yes/no question or a small set of options, such as content moderation, classification, or quality checks.
According to OpenAI, the Decisions API runs roughly ten times faster than existing alternatives for these kinds of evaluations. That speed boost comes from not having to generate a complete sentence or paragraph, only a concise decision.
OpenAI announced the Decisions API on October 7, 2026, and moved it to beta within a few days. At the time of the latest available information, it was in its beta phase, meaning it was available for developers to test but still subject to change.
It gives short, structured answers like yes/no, multiple-choice selections, scores, or probabilities. It does not write out full sentences or paragraphs.
It is currently in beta, which means OpenAI has made it available for developers to test. Pricing details were not included in the available information.
Standard OpenAI APIs generate full text responses that programs must interpret. The Decisions API returns direct, structured decisions — probabilities, choices, and scores — so apps can act on the result instantly.
