The model handles yes/no questions, named-category selection, and rubric-based scoring, with multiple questions able to share one input per request, and it is callable through the AI SDK decision API, the OpenAI-compatible Decisions API, or the TypeSafe-compatible API using only an AI Gateway API key and no separate Azure account or deployment. Developers reference it as `microsoft/microsoft-decision-1`, and its calls appear in AI Gateway logs and count toward budgets alongside other model requests.", "body_md": "[Decision-1 from Microsoft](https://vercel.com/ai-gateway/models/microsoft-decision-1) is now available on [AI Gateway](https://vercel.com/ai-gateway). It answers typed questions about text with probabilities, choices, and scores. It can be used to classify support requests, select the next step in a workflow, or assess an AI response against a rubric.\n\nThe model can answer yes/no questions, choose among named categories, or score an input against an ordered set of criteria. Multiple questions can share the same input in one request. Choice and score answers include probabilities for each option, so your application can decide when to act or send an uncertain result for review.\n\nCall Decision-1 through the [AI SDK decision API](https://vercel.com/docs/ai-gateway/modalities/decision), the [OpenAI-compatible Decisions API](https://vercel.com/docs/ai-gateway/sdks-and-apis/openai-decisions), or the [TypeSafe-compatible API](https://vercel.com/docs/ai-gateway/sdks-and-apis/typesafe). You only need an AI Gateway API key, with no separate Azure account or deployment.\n\nTo get started, use `microsoft/microsoft-decision-1` as the model name in your requests:\n\nAI Gateway provides a unified way to access models and track usage and cost. Decision calls appear in [logs](https://vercel.com/docs/ai-gateway/observability-and-spend/logs) and count toward [budgets](https://vercel.com/docs/ai-gateway/observability-and-spend/budgets) alongside other model requests.\n\nSee the [decision documentation](https://vercel.com/docs/ai-gateway/modalities/decision) for Choice, Score, and Boolean questions. To pick a decision model, browse the [available models](https://vercel.com/ai-gateway/models?capabilities=decision) or read our [decision model guides](https://vercel.com/i/category/decision-models).", "url": "https://wpnews.pro/news/microsoft-decision-1-now-available-on-ai-gateway", "canonical_source": "https://vercel.com/changelog/microsoft-decision-1-now-available-on-ai-gateway", "published_at": "2026-10-09 00:00:00+00:00", "updated_at": "2026-10-10 05:01:23.316580+00:00", "lang": "en", "topics": ["ai-products", "ai-tools", "large-language-models", "artificial-intelligence", "developer-tools"], "entities": ["Microsoft", "Decision-1", "Vercel", "AI Gateway", "AI SDK", "OpenAI-compatible Decisions API", "TypeSafe", "Azure"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/microsoft-decision-1-now-available-on-ai-gateway", "markdown": "https://wpnews.pro/news/microsoft-decision-1-now-available-on-ai-gateway.md", "text": "https://wpnews.pro/news/microsoft-decision-1-now-available-on-ai-gateway.txt", "jsonld": "https://wpnews.pro/news/microsoft-decision-1-now-available-on-ai-gateway.jsonld"}}
