OpenAI's Decisions API now accessible via AI Gateway's `/v1/decisions` endpoint—returns probabilities and choices instead of text, replacing separate classification pipelines with typed question-answering against shared input.
Summary
Consolidates routing, triage, and scoring into a single request with predicate, choice, and score question types. Eliminates prompt engineering overhead for classification tasks by treating decisions as a first-class API primitive.

Implementation verdict
Ready to use now. Requires OpenAI SDK 7.30.0+ (JS) or 3.26.0+ (Python); point baseURL to AI Gateway and call `decisions.create()`. Replaces chained prompt-based classification patterns. Trial immediately if you're currently parsing LLM output for routing decisions.
