Product brief
What Microsoft-Decision-1 does.
Microsoft-Decision-1 is a decision-scoring model for routing, classification, verification and agent control. Give it fixed options and it returns a calibrated probability for each in a single pass, as structured output software can act on directly. Post-trained from Qwen3.5-9B, it is about 35x faster than GPT-6 Sol at median latency, per Microsoft. Available now in Microsoft Foundry at $0.042 per million input tokens, with free output.
