微软于2026年10月9日正式发布名为Microsoft-Decision-1的人工智能模型，该模型基于阿里巴巴的Qwen3.5-9B开发，拥有90亿参数 1。Microsoft-Decision-1并非用于生成开放文本，而是专门针对路由、分类、优先级划分及验证和工作流控制等高频低延迟任务优化，核心功能是从固定选项中快速选择答案并返回校准后的概率分数 1。这一模型目前通过Microsoft Foundry公开预览版以及OpenRouter平台提供服务，但不向公众分发模型权重，仅支持托管API访问 1。
在性能表现方面，微软声称该模型在包含36个基准测试和约15万个保留问题的评估中达到了83.5%的准确率，其扰动稳定性为98.7% 1。速度上，Microsoft-Decision-1比GPT-6 Sol快约35倍，比Quyet-1.0-Large快4.5倍 1。该模型最大支持32,000个输入令牌，定价策略极具竞争力，每百万输入令牌收费0.042美元，而输出部分免费 1。微软内部计划将其应用于事件响应、质量控制及科学发现等领域，且Satya Nadella亲自介绍了这款新产品 1。关于未来技术路线，微软表示计划后续将底层模型迁移至Microsoft AI（MAI）和OpenAI的技术栈 1。
Microsoft launched Microsoft-Decision-1 on October 9, 2026, introducing a specialized artificial intelligence model designed for high-frequency, low-latency tasks such as routing, classification, prioritization, and validation 1. The model was personally introduced by CEO Satya Nadella and is engineered to select answers from fixed options while returning calibrated probability scores, rather than generating open-ended text 1. Built upon the Alibaba Qwen3.5-9B architecture, the system features 9 billion parameters 1.
The company reports that Microsoft-Decision-1 achieved an accuracy of 83.5% across 36 benchmarks and approximately 150,000 held-out questions 1. In terms of performance speed, the model claims to be roughly 35 times faster than GPT-6 Sol and 4.5 times faster than Quyet-1.0-Large, while maintaining a perturbation stability rating of 98.7% 1. Internally, Microsoft utilizes this technology for event response, quality control, and scientific discovery applications 1.
Availability is currently restricted to hosted APIs via Microsoft Foundry in public preview and OpenRouter, with no plan to distribute the model weights publicly 1. The pricing structure is set at $0.042 per million input tokens, with output generation provided free of charge 1. Users are limited to a maximum input size of 32,000 tokens 1. Looking ahead, Microsoft stated its intention to migrate the underlying model to proprietary Microsoft AI (MAI) and OpenAI technologies in the future 1.
