OpenAI Introduces Decisions API for Choosing App Actions From Text and Images

OpenAI introduced the Decisions API, which lets developers define a question and a limited set of answers so a model can choose what an app does next from text or image input. OpenAI’s DevDay 2026 recap says the API is available in limited preview.

Full Report

OpenAI published a video introducing the Decisions API on October 6, 2026. Developers provide text or image input, define a question and its possible answers, and use the model’s choice to determine the next action in an app. OpenAI says the API is powered by GPT-6 Luna and focuses on a small set of choices to support responsive interactions.

The video illustrates classifying text and routing sales leads, as well as making decisions from images. It also presents voice-conversation examples and a demonstration combining voice, visual understanding and quick decisions with GPT-Live-1 and a Microduck; another segment features the Lavender robot.

OpenAI’s DevDay 2026 recap lists the Decisions API as available in limited preview. The introduction’s central approach is to have developers define the question and answer space in advance, so a model’s selection can feed into an app’s next step rather than simply produce a general text response.

Why This Matters

For apps that need to classify inputs, route requests or choose a next action, a defined answer set can map model choices directly to application workflows. OpenAI’s examples span text, images and voice, and the API is currently in limited preview.
