Brazilian authorities have ordered 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 decision follows broader regulatory pressure on how social platforms use public posts and account data for AI training, including similar scrutiny in Europe. Brazilian authorities have raised concerns regarding the lawful basis and consent for using users’ personal data for training Grok.
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. The move highlights the growing regulatory scrutiny on the use of public data for AI training.
