Microsoft and Mistral Expand AI Infrastructure Partnership Across Europe

Microsoft and Mistral are expanding their strategic partnership through a multi-billion-dollar deal focused on AI infrastructure in Europe. Mistral is adding thousands of Nvidia Vera Rubin GPUs, and Microsoft will use that capacity for its cloud and AI services. The move positions the partnership around enterprise AI demand, regional infrastructure, and access to high-performance compute.

Mistral’s Medium 3.5 and OCR 4 models are now available in Microsoft Foundry. Medium 3.5 is also available in Copilot Studio, extending Mistral model access into Microsoft’s app-building environment. Companies can run Mistral models through Azure Local in the cloud, in their own environments, or completely offline.

The offering targets regulated industries including finance, healthcare, and manufacturing. The key message is control: Microsoft President Brad Smith said Europe should be able to use powerful AI without giving up control over its data. For buyers in sensitive sectors, the deployment options signal a focus on data residency, operational control, and compliance needs.

Mistral CEO Arthur Mensch sees the partnership as a way to reach companies and public institutions worldwide. The article also notes Mensch’s recent warning that companies risk exposing trade secrets when they use closed AI models. Mistral, founded in 2023, recently grew revenue twentyfold to a run rate above $400 million, invested 1.2 billion euros in data centers in Sweden, and is reportedly negotiating a new funding round of about 3 billion euros at a valuation of roughly 20 billion euros.
