By default, Mistral AI may use the prompts you type and the AI responses you receive to improve and train its AI models, unless you actively opt out. This does not apply if you pay for an API plan or use Le Chat Enterprise.

Free-tier users' conversations are treated as training data by default, meaning your personal questions, instructions, and AI responses could influence how Mistral AI's models behave for all users unless you take action to opt out.
The updated policy now explicitly includes data accessed through third-party services and integrations users connect to Mistral AI Products as 'Input' data subject to collection and use. The policy removed its prior statement that Input and Output data are not used to train AI models when using Le Chat Enterprise or paid versions of Mistral APIs. This creates operational ambiguity: users of paid services and Enterprise customers no longer have a documented commitment that their data will be excluded from model training, though the privacy policy does not affirmatively state that model training now occurs. The policy also changed language describing product improvement from 'aggregated and anonymous statistics' to 'aggregated or anonymous datasets or statistics,' broadening the stated scope of what can be collected for improvement purposes.
