Decision-1 handles three question types: yes/no, a choice among named categories, and a score against an ordered set of criteria. Several questions can share the same input in one request.
Choice and score answers return a probability for each option, so an application can decide when to act and send uncertain results to review instead.
It is callable through the AI SDK decision API (experimental_decide), an OpenAI-compatible Decisions API, or a TypeSafe-compatible API, using the model name microsoft/microsoft-decision-1.
Vercel says decision calls appear in AI Gateway logs and count toward budgets alongside other model requests.
