Microsoft and Mistral in Multi-Billion-Dollar AI Infrastructure Deal

Microsoft and Mistral Expand Partnership with Major AI Infrastructure Investment

Microsoft and Mistral have deepened their strategic collaboration through a multi-billion-dollar agreement focused on building out artificial intelligence infrastructure across Europe. The deal involves Mistral adding thousands of Nvidia Vera Rubin graphics processing units to its operations, and Microsoft will tap into that expanded capacity for its cloud and AI services.

Mistral's Medium 3.5 and OCR 4 models are now available through Microsoft Foundry, the company's platform for deploying and managing AI models. Medium 3.5 is also accessible within Copilot Studio, Microsoft's tool for building custom copilots. Businesses can run Mistral models via Azure Local, either in the cloud, within their own environments, or completely offline. This offering is designed for regulated industries such as finance, healthcare, and manufacturing, where data sovereignty and security are critical.

Data Control and European Sovereignty

Microsoft President Brad Smith stated that Europe should be able to use powerful AI without giving up control over its data. The partnership aims to provide European organizations with advanced AI capabilities while ensuring they retain authority over their information.

Mistral CEO Arthur Mensch described the partnership as a way to reach companies and public institutions around the world. Mensch recently warned that businesses risk exposing trade secrets when they rely on closed AI models, highlighting the importance of open and transparent AI systems.
