Elon Musk’s X is being investigated by authorities in Europe, India and Malaysia after its Grok chatbot let users create and share AI-generated sexualized images of children and women.

British media watchdog Ofcom also said it’s requested information from X, which is owned by xAI, concerning the Grok issues. And on Sunday, a member of Brazil’s parliament said on social media that she’s asked the country’s federal public prosecutor and data protection authority to suspend use of Grok until an investigation is completed.

The probes follow a global surge over the past few weeks in the use of Grok to create and share nonconsensual, intimate images, or NCII, derived from photos or videos of real people in response to user’s prompts. The concerning images have been widely shared on X.

Musk’s company recently updated its Grok Imagine features, enabling easier image generation from text-based prompts on the platform.

While safety experts and tech critics decried the proliferation of exploitative images and clips on X, Musk appeared to mock the situation by sharing an array of Grok-generated images, including one depicting himself in a bikini, punctuated by laughing-crying emojis.
