Microsoft has released Microsoft-Decision-1, a model for fast decision-making, now available in its Foundry platform, according to Satya Nadella's X posts.

Nadella says the model will come to OpenRouter soon, but no date has been reported.

Microsoft says the model outperforms both LLMs and other decision models on structured decision tasks in latency and quality. A later Microsoft post says it was post-trained on Qwen3.5-9B for single-pass decision scoring and achieved the highest accuracy in a 36-benchmark comparison of nearly 150,000 questions, running 4.5 times faster than Quyet-1.0-Large and 35 times faster than GPT-6 Sol. These performance claims are Microsoft's own and have not been independently verified. Microsoft says it is testing the model internally for incident response, quality control, and scientific discovery, and plans to rebase it on other models, including MAI and OpenAI models.
