Brazilian authorities have told X to stop collecting and using users’ personal data to train its Grok AI chatbot, citing concerns about lawful basis and consent under local privacy rules.
The move follows broader regulatory pressure on how social platforms use public posts and account data for AI training, including similar scrutiny in Europe.
For X, the decision could mean pausing or changing how Grok is trained for Brazilian users until clearer opt-in or other compliant mechanisms are in place.
