X/Twitter has activated a setting that is ON by default and allows it to use all of your data to train Grok. The change was not announced.
You can disable it through a browser
You canNOT disable it using the mobile app
If you do not want your comments, posts, images, interactions and the results to be used to train this Artificial Intelligence engine, go to …More > Settings and Privacy > Privacy and Safety > (scroll to the bottom of the “Data sharing and personalization” section) select Grok > Deselect the checkbox, and delete your conversation.
Doing that will not delete your tweets.
