New York —

Elon Musk’s xAI sued a user on Tuesday, alleging he used the Grok chatbot to create child sexual abuse materials. It’s one of the first lawsuits filed by a tech company against users who allegedly create explicit content with AI.

Musk’s company alleged in the lawsuit that a user named Terry Wayne Harwood violated its terms of service “to convert non-sexual photographs into sexually explicit images without the photograph subjects’ knowledge or consent.” Harwood, along with three other men, was arrested earlier this year in South Carolina on multiple counts of alleged sexual exploitation of a minor.

CNN has reached out to the attorney representing Harwood in his criminal case for comment.

The lawsuit, filed in the US District Court for the Northern District of Texas, alleges Harwood created multiple xAI accounts and entered “misleading prompts” to create explicit deepfakes of both minors and adults.
