Vercel Integrates Microsoft Decision-1, Enabling Structured Decisions Without Azure

Vercel AI Gateway has integrated the Microsoft Decision-1 model, enabling developers to execute structured decision tasks through a unified interface.

Previously, accessing such specialized decision models typically required configuring a separate Azure account and deployment environment. Now, developers can directly request the model to answer yes/no questions, choose categories, or score inputs using only a Vercel AI Gateway API key.

The model returns options with associated probabilities, helping applications decide whether to act automatically or route uncertain results for human review. This update lowers integration barriers, though specific inference performance relies on Microsoft's official benchmarks, as Vercel provides no independent reproduction data.
