Microsoft launches Decision-1 built on Alibaba's Qwen

KEY FACTS

On October 12, Microsoft released Microsoft-Decision-1, a decision model post-trained on Alibaba's Qwen3.5-9B.
The model outperforms LLMs and models such as Jev 1.13.0 in latency and accuracy on structured decision tasks.
Microsoft's Xbox research team has already used the model to process over 10,000 player feedback entries.
Microsoft CEO Nadella said the company is testing the model in areas including incident response, quality control, and scientific discovery.
Of the 129 open-source decision model projects on HuggingFace, 84 are based on Alibaba's Qwen, accounting for over 65%.

PHYSIX OBSERVATION

Microsoft betting its decision model on Alibaba's Qwen shows that China's open-source foundation is becoming the default choice for overseas giants building vertical models. Decision models compete not on conversation but on judgment; they are small and fast, exactly meeting the hard demand for frequent agent decisions. The notable signal: competition at the model layer is shifting from general capabilities to who controls the high-frequency decision entry point.
