X Activates AI Training on User Posts Without Public Notice

Users can opt out of Grok AI training, but the default setting collects data from all posts and interactions.

X is using user posts and interactions to train its AI assistant, Grok, without an initial public announcement.
The setting to opt out of data sharing is available only through the desktop version of X.
The European Data Protection Commission (DPC) has expressed surprise and is awaiting a response from X.
Grok is designed to provide candid and humorous responses, available exclusively to X subscribers.
Users can delete their conversation history with Grok within 30 days unless retained for legal reasons.
