[Microsoft launches Decision-1 model in Foundry](https://www.testingcatalog.com/microsoft-launches-decision-1-model-in-foundry/)

MICROSOFT : A new Microsoft-Decision-1 model for fast decision-making is now available on Microsoft Foundry.

Microsoft-Decision-1 was post-trained on Qwen3.5-9B for fast, single-pass decision scoring. Later, Microsoft is planning to rebase it on other models, including MAI and OpenAI models. 

> "Microsoft-Decision-1 achieved the highest accuracy in our 36-benchmark comparison, spanning nearly 150,000 questions across benchmarks kept blind from training."

> "4.5 times quicker than Quyet-1.0-Large, the runner-up, and 35 times quicker than GPT-6 Sol."

> "We’re already testing it across Microsoft for everything from incident response and quality control to scientific discovery."

Everyone is testing
