Mistral and Mozilla are bringing open, private and multilingual AI to your web browser

Today, we are announcing a partnership with Mozilla to bring privacy, control and choice to people using AI to browse online.

Firefox Smart Window (beta), Mozilla’s AI browsing assistant, is now powered by Mistral models. Smart Window helps you make sense of complex searches, remember something important you clicked away from and source information important to you based on your browser tabs. Mistral will help power Smart Window for users in France and North America, with the United Kingdom and Germany expected to follow later this year.

This partnership represents two open source advocates working together to bring Mistal’s scientific innovations to consumers around the world. We are building AI systems that are trained and fine-tuned on regional languages, dialects and cultural context, so anyone can get responses that understand their local nuance.

This announcement is important to the global AI ecosystem for four reasons:

Open technology needs open distribution: Mozilla has spent more than two decades fighting for an open web and Mistral has been releasing open weight, frontier models since our first release. This partnership is about demonstrating the potential of open source to serve people around the world.

AI optimized for local countries and cultures, not exported to them: We’re fine-tuning our models on regional languages and dialects so that everyone, no matter where they are or how they communicate, can benefit from AI that understands their local nuances. This partnership extends this capability to people who use Firefox worldwide so that their AI experience feels native to them.
