Microsoft now has its own decision model. Like the ones from OpenAI , Cloudflare , and the "original" from Jev , Decision-1 is built for fast, structured decisions. According to Microsoft , it handles classifications, evaluations, and routing decisions and has "the potential" to "guide and control agents through complex environments." Decision-1 is based on Qwen3.5-9B. Microsoft says it's the most accurate model tested across 36 benchmarks covering nearly 150,000 questions. On speed, it's 2.5 times faster than the runner-up, H2O-Lightning-4B. Cloudflare's open-source Clef models, which are also based on Qwen, weren't included in the comparison. Decision-1 is available through Microsoft Foundry and OpenRouter . Input tokens cost $0.042 per million, and output tokens are free.
