On October 12, Microsoft released Microsoft-Decision-1, a new decision model post-trained on Alibaba's Qwen3.5-9B. Microsoft stated the model outperforms LLMs and popular decision models like Jev 1.13.0 in latency and accuracy for structured decision tasks. Microsoft's Xbox research team has used it to process over 10,000 player feedback items. CEO Satya Nadella said on social media that due to the model's strong performance, Microsoft is testing it across all areas, including incident response, quality control, and scientific discovery. The report notes that a wave of decision models, which output predictions, probabilities, and confidence scores rather than natural language, was sparked by the Jev model's popularity in September. Statistics show that of 129 open-source decision model projects on HuggingFace, 84 (over 65%) are based on Alibaba's Qwen, including models from Microsoft, Perplexity, Cloudflare, and H2O.ai.

On October 12, Microsoft unveiled a new decision model, Microsoft-Decision-1, built on Alibaba's Qwen. According to Microsoft, the model was post-trained on Qwen3.5-9B and outperforms popular decision models such as LLM and Jev 1.13.0 in terms of latency and accuracy on structured decision-making tasks.
Microsoft's Xbox research team has already used the model to process over 10,000 pieces of player feedback. Microsoft CEO Satya Nadella also revealed on social media that, given the model's strong performance, Microsoft is testing its application across all areas, including incident response, quality control, and scientific discovery.
The Jev model's surge in popularity in September sparked a wave of decision models. Unlike large language models (LLMs), these models do not generate natural language; instead, they output predicted values, probabilities, and confidence scores. They are significantly smaller than LLMs and respond faster, making them well suited to the frequent judgment calls required in AI tasks.
Statistics show that among 129 open-source decision model projects on HuggingFace, 84 are developed based on Alibaba's Qwen — more than 65% of the total. Notable decision models from companies including Microsoft, Perplexity, Cloudflare, and H2O.ai all adopt Alibaba's Qwen. (Hard AI)
