The European Commission has launched an investigation into Elon Musk’s X over the production of sexually explicit images and the spreading of possible child sexual abuse material by the platform’s AI chatbot feature, Grok.

The formal inquiry, launched on Monday, also extends an investigation into X’s recommender systems, algorithms that help users discover new content.

Grok has sparked international outrage by allowing users to digitally strip women and children and put them into provocative poses. Grok AI generated about 3m sexualised images in less than two weeks, including 23,000 that appeared to depict children, according to researchers at the Center for Countering Digital Hate.
