Microsoft taps Chinese open-weight model for new decision AI · 3 sources tracked

Microsoft is leveraging an open-weight model from a Chinese AI lab, specifically Qwen3.5-9B, as the foundation for its new decision-making model, Microsoft-Decision-1. This move aims to challenge existing decision models like Jevíčko. While the initial version uses the Chinese model, Microsoft plans to integrate its own technology in future iterations. Decision models are highlighted for their ability to provide structured outputs for immediate software action at low cost and high performance, though potential errors and their magnification are also noted.
