Mistral AI now uses user inputs and outputs for model training by default across its platform, with opt-out available only to enterprise customers. The policy applies to all free and paid tiers except the enterprise tier.

Mistral's updated data handling policy marks a shift in how the AI company approaches user data. Previously, users could opt out of having their conversations used for training purposes. Under the new arrangement, only enterprise tier subscribers receive automatic opt-out protection. The change affects all interactions with Mistral's models unless users fall into the enterprise category. Free tier and standard paid tier users must now explicitly request to exclude their data from training, reversing the prior opt-in model for most customers. The policy details were published in Mistral's help documentation. The announcement generated significant discussion among developers on Hacker News, where the post received 148 points and 71 comments, reflecting community concern about data usage practices and privacy implications. Mistral joins other AI providers in leveraging user interactions for model improvement, though the broader implications for data privacy and user consent continue to shape conversations in the AI community.
