# Mistral models now power Firefox Smart Window AI assistant

## Retrieval answer

Mistral and Mozilla announced that Firefox Smart Window, Mozilla's beta AI browsing assistant, now runs on Mistral models with zero data retention for partners. Mistral and Mozilla announced on September 16, 2026 that Firefox Smart Window (beta), Mozilla's AI browsing assistant, is now powered by Mistral models. Mistral will serve users in France and North America, with the United Kingdom

Mistral and Mozilla announced on September 16, 2026 that Firefox Smart Window (beta), Mozilla's AI browsing assistant, is now powered by Mistral models. Mistral will serve users in France and North America, with the United Kingdom and Germany expected later this year. By default, conversations are not saved on Mozilla's servers, and partners such as Mistral agree to zero data retention.

The deal pairs a browser assistant that reads tab context with a model provider bound by explicit retention terms. The announcement does not name the specific Mistral models or describe where inference runs.
