March 16 (Reuters) - Three Tennessee plaintiffs, including two minors, sued Elon Musk's xAI on Monday, alleging that it knowingly designed its Grok image generator to let people create sexually explicit content by using real photos of others.

The lawsuit, filed in the San Jose, California federal court, is seeking class-action status for people in the United States who were "reasonably identifiable" in sexualized images or videos generated by Grok based on real images of themselves.

The artificial intelligence company did not immediately respond to a Reuters request for comment.

After an outcry over sexually explicit content generated by the chatbot, xAI said in January that it had blocked all users from editing images of "real people in revealing clothing" and from generating images of people in revealing clothing in "jurisdictions where it's illegal."

* Governments and regulators around the world have alsosince launched probes, imposed bans and demanded safeguards in agrowing push to curb illegal and offensive material. * The lawsuit claims xAI failed to install safeguards toprevent its systems from generating sexual content involvingminors. All three plaintiffs were minors at the time the imageswere generated. * Plaintiffs allege their real images were digitally alteredinto explicit content and then shared online through platforms,causing emotional distress and creating a public nuisance. * They are seeking unspecified damages, legal fees, and aninjunction requiring xAI to halt the alleged practices. * "These are children whose school photographs and familypictures were turned into child sexual abuse material,"plaintiffs' counsel Annika Martin of Lieff Cabraser Heimann &Bernstein said in a statement. "Elon Musk and xAI deliberatelydesigned Grok to produce sexually explicit content for financialgain, with no regard for the children and adults who would beharmed."
