Microsoft-Decision-1 is the decision model from Microsoft, delivered through Foundry, that answers bounded questions rather than generating text.
Product and engineering teams frequently need a model to pick among options rather than write prose, whether routing a request or grading a record. Microsoft-Decision-1 answers those bounded questions directly, returning a decision the calling software can act on without parsing generated text.
Offered through Microsoft Foundry and built on a Qwen3.5-9B backbone, it joins the emerging decision-model category alongside Jev from TypeSafe AI and Clef from Cloudflare. Microsoft positions it on speed, measuring it faster than rival small decision models for latency-sensitive routing and classification.
