The European Union has launched a wide-reaching investigation into Elon Musk’s Grok chatbot on X following global outrage over its ability to generate sexually explicit images, including of children.

The scandal erupted at the end of last year when the AI chatbot churned out a barrage of digitally undressed images of women and children in response to requests from users.

The global outcry that followed was met by an initial announcement by X that the tool would be limited to paying subscribers, but the company eventually prevented all users from using Grok to create images of real people in revealing clothing.
