Microsoft announced an expansion of its strategic partnership with France-based AI firm Mistral to expand European AI infrastructure. Under the terms, Microsoft will bring Mistral’s frontier and efficiency AI models across Microsoft Foundry, Copilot Studio, Azure, and the entire Microsoft platform, combining them with its security, compliance, and cloud-to-edge platform. Microsoft says this expansion is a “multi-billion dollar agreement” that will help expand European AI infrastructure, with Mistral adding to its GPU capacity by purchasing “thousands” of the latest NVIDIA Vera Rubin GPUs. Starting today, the Mistral Medium 3.5 and OCR 4 AI models are available in Microsoft Foundry, Medium 3.5 is available in Copilot Studio, and financial services, manufacturing, healthcare, and other regulated businesses can run Mistral-based AI apps in Azure or Azure Local.
