What they're building
Europe's strongest frontier-model contender and the flagship of sovereign AI. Mistral ships open-weight models (Small 4 under Apache 2.0, Large 3), the Le Chat assistant, and Mistral Compute, a European alternative to US cloud AI.
Latest developments
- Mistral Medium 3.5 (April 2026) is the current general frontier tier.
- Mistral Small 4 (March 2026): multimodal, 256K context, Apache 2.0.
- Mistral Compute, built with Nvidia, positions the company as Europe's AI infrastructure provider.
Why it matters
Governments and regulated industries want AI they can run themselves. Mistral is the leading non-US, non-Chinese answer to that demand.
