The model answers typed questions about text with probabilities, choices, and scores. It supports yes/no questions, selection among named categories, and scoring against ordered criteria; multiple questions can share one input, and choice or score answers include probabilities for each option.
The changelog documents access through the AI SDK decision API, an OpenAI-compatible Decisions API, and a TypeSafe-compatible API. Vercel says an AI Gateway API key is sufficient, with no separate Azure account or deployment required. Calls appear in Gateway logs and count toward budgets alongside other model requests.
