The model is being used internally to power LLM judges, manage incident response, and screen candidate hypotheses in scientific discovery pipelines. Future updates will include rebasing the tool on other architectures, such as MAI and OpenAI models, to refine latency and quality. This release follows a broader industry trend of deploying specialized decision-making architectures to outperform general-purpose large language models.

Microsoft Ships Decision-1 to Foundry with 35x Speed Over GPT-6 Sol
AI11 days ago
Nearly 150,000 blind questions across 36 different benchmarks resulted in the highest accuracy for Microsoft's latest structured-task model. Known as Microsoft-Decision-1, the tool is now available on Microsoft Foundry and was post-trained on Qwen3.5-9B to enable fast, single-pass decision scoring. The company reports that the model operates 4.5 times quicker than its closest rival, Quyet-1.0-Large, and 35 times faster than GPT-6 Sol.
