Microsoft's Decision-1 model enters the fast-growing AI decision model race
Microsoft released Decision-1, a Qwen3.5-9B decision model claiming top accuracy and low latency.
Microsoft launched Decision-1, a decision model based on Qwen3.5-9B for classifications, evaluations, routing, and potentially guiding agents. Microsoft says it led 36 benchmarks covering nearly 150,000 questions, scoring 83.5% accuracy at 85 ms latency and running 2.5 times faster than H2O-Lightning-4B, ahead of Jev 1.13.0. Cloudflare's Qwen-based Clef models were excluded from the comparison. Decision-1 is available on Microsoft Foundry and OpenRouter at $0.042 per million input tokens, with output tokens free.
