Ashley St Clair, the mother of one of Elon Musk's children, has sued his company xAI over sexualised deepfakes of her created on social media platform X.
The lawsuit filed in New York on Thursday alleges the Grok AI tool created sexually explicit pictures of St Clair.
The parent company of X and Grok, xAI, has counter-sued St Clair for violating its terms of service.
X did not respond directly to BBC News's enquiries about the lawsuits.
"We intend to hold Grok accountable and to help establish clear legal boundaries for the entire public's benefit to prevent AI from being weaponised for abuse," St Clair's lawyer Carrie Goldberg told BBC News.
