Microsoft releases Microsoft-Decision-1, a 9B model for fast decisions
AIMicrosoft has made Microsoft-Decision-1 available on Microsoft Foundry, a model post-trained on Qwen3.5-9B for fast, single-pass decision scoring. Microsoft says it achieved the highest accuracy across a 36-benchmark comparison of nearly 150,000 questions, and runs 4.5 times faster than Quyet-1.0-Large and 35 times faster than GPT-6 Sol. Microsoft plans to rebase it on other models, including MAI and OpenAI models.
