Decisions API enters public beta, offering faster text and image evaluation
Key points
- Decisions API is in public beta.
- Evaluates text, images, or both.
- Returns typed answers 10x faster than Responses API.
- Uses gpt-6-luna model.
- Supports predicate, choice, and score question types.
Decisions API Public Beta Launch
The Decisions API has entered public beta, providing developers with a new tool for evaluating content. This API is designed to process text, images, or a combination of both, delivering specific typed answers. It is expected to reach General Availability (GA) in the coming weeks.
Performance and Functionality
The Decisions API offers a significant speed improvement, returning results up to 10 times faster than the Responses API. It can provide the probability of a condition being true, a selection from a fixed set of choices, or a score against a rubric. These outputs are intended for tasks such as classifying content, routing requests, and prioritizing work within applications.
Technical Details and Model
Currently, the Decisions API exclusively uses the gpt-6-luna model. Developers interact with the API via a dedicated POST /v1/decisions endpoint. Requests consist of an input, questions, and a model specification, with responses containing an answers array identified by unique question names.
Question Types
The API supports various question types, including 'choice' for unordered categories and 'score' for ordered levels, which calculates a probability-weighted average. A 'predicate' question type can be used to check for specific conditions, such as visible damage in an image, by providing instructions alongside the input.
Distinction from Other APIs
The Decisions API is distinct from the Responses API with Structured Outputs or function calling. While the Responses API is suitable for generating JSON objects or tool calls, the Decisions API focuses on providing direct, typed answers for specific evaluation needs.

The Decisions API is now in public beta, providing a new method for evaluating text and images to return typed answers up to 10 times faster than the existing Responses API. This development offers developers a dedicated tool for content classification, request routing, and work prioritization based on probabilities, choices, or scores.
