- Microsoft launches Microsoft-Decision-1 for routing, classification, verification, and agent control.
- The model returns calibrated probabilities for fixed answer options instead of generating free-form text.
- It is built through post-training based on Alibaba's Qwen3.5-9B model architecture.
- Available right now for developers and enterprises via Microsoft Foundry and OpenRouter.
The artificial intelligence landscape welcomes a new specialized tool as Microsoft officially rolls out Microsoft-Decision-1. This newly introduced system functions primarily as a robust decision model tailored specifically for handling task routing, data classification, verification processes, and intelligent agent control.
A standout characteristic of Microsoft-Decision-1 is its role as a decision-scoring model. Rather than generating lengthy descriptive text like traditional language models, this system evaluates fixed answer options and outputs precise, calibrated probabilities for each potential choice.

Shifting away from standard text generation toward probabilistic scoring significantly minimizes hallucination risks. It allows automated pipelines and decision trees to parse deterministic numerical scores directly, which is crucial for enterprise workflow automation requiring high reliability.
Under the hood, the foundation of this release relies on advanced post-training procedures applied to Alibaba's Qwen3.5-9B model. This approach demonstrates how major tech players leverage and refine powerful open-weight architectures to build task-specific intelligence.
Developers and organizations looking to integrate this capability into their tech stacks can access Microsoft-Decision-1 immediately, as it has been made live on both Microsoft Foundry and OpenRouter.
