“The reports about Grok raise deeply troubling questions,” said William Malcolm of the Information Commissioner’s Office.

Grok was developed by Musk’s xAI in 2023, designed to be a “truth-seeking” assistant with a witty, rebellious personality.

Integrated into X, formerly Twitter, it uses real-time data from the platform to generate text, images and code.

But complaints have mounted that Grok was being used to generate sexual photos of real women and children, and now the Information Commissioner’s Office (ICO) is investigating.
