Elon Musk-led social media platform X is training Grok, its AI chatbot, on users’ data, and that’s opt-out, not opt-in. If you’re an X user, that means Grok is already being trained on your posts if you haven’t explicitly told it not to.
Over the past day or so, users of the platform noticed the checkbox to opt out of this data usage in X’s privacy settings. The discovery was accompanied by outrage that user data was being used this way to begin with.
The social media posts about this sometimes seem to suggest that Grok has only just begun training on X users’ data, but users actually don’t know for sure when it started happening.
Earlier today, X’s Safety account tweeted, “All X users have the ability to control whether their public posts can be used to train Grok, the AI search assistant.” But it didn’t clarify either when the option became available or when the data collection began.
You cannot currently disable it in the mobile apps, but you can on mobile web, and X says the option is coming to the apps soon.
On the privacy settings page, X says:
To continuously improve your experience, we may utilize your X posts as well as your user interactions, inputs, and results with Grok for training and fine-tuning purposes. This also means that your interactions, inputs, and results may also be shared with our service provider xAI for these purposes.
X’s privacy policy has allowed for this since at least September 2023.
