An expanded proposed class-action lawsuit against X and xAI, filed on Tuesday, alleges that a man used the Grok AI tool to generate roughly 7,000 sexually explicit images and videos of his stepdaughter from a single photograph taken when she was 11. According to the complaint, Grok produced extreme material depicting incest and rape without flagging it, and xAI's safety system intervened only when the man entered a prompt for "gang rape," triggering a report to the National Center for Missing and Exploited Children (NCMEC). The case matters because the girls now accuse the companies not only of building "nudify" tools but of actively obstructing police investigations into AI-generated child sexual abuse material (CSAM).

The complaint alleges xAI repeatedly refused to share information such as the user's IP address, stymieing investigators for weeks, and notes NCMEC found that 90 percent of xAI's tip-line reports in early 2026 were unactionable for the same reason. The stepfather was eventually arrested after a device warrant, and shot himself two days after being released on bail, leaving the girl (Jane Doe 4) with anxiety, depression and suicidal thoughts. A second victim, Jane Doe 5, was targeted by an adult family friend. Lawyers also added Stability AI as a defendant, alleging its open-weight models were trained on CSAM and underpin third-party "nudify" apps. Elon Musk has denied Grok has ever been used to generate child sex images; X and xAI did not respond to requests for comment.
