Decisions API evaluates text, images, and JSON and returns typed answers.
Decisions API evaluates text, images, and JSON and returns typed answers: the probability that a condition is true, a choice from a fixed set, or a score against a rubric. Developers define a question and its allowed answers, then provide context as text, images, or native JSON.
Decisions API serves applications and agents that make many small decisions throughout a workflow, such as how to classify an input, where to route a request, or which action to take next. It returns typed answers about 10x faster than the Responses API.
Adds products that compete with one of Decisions API’s direct competitors but not with Decisions API itself. They are shaded, and Linked Through names the direct competitor each one competes with.
