Firefox Smart Window runs on Mistral models in beta

Sources: primary, discussion
Summary: Mistral states that Firefox Smart Window, Mozilla's AI browsing assistant, is in beta powered by Mistral models for users in France and North America, with the United Kingdom and Germany expected to follow later this year. Mozilla states that conversations are not saved on its servers by default and that partners including Mistral agree to zero data retention. Neither company published model identifiers, context limits or evaluation results.
Why it matters: A major browser is routing assistant traffic to a provider other than its search incumbent, and the only published technical substance is the data-handling commitment.
