The XAI class covers all U.S. individuals whose “realistic images of minors” have been altered using Grok “to produce images or videos depicting sexually suggestive behavior or content with their faces and/or other reasonably identifiable distinguishing features.” The Stability AI class includes US individuals similarly harmed using “software built on the Stability AI model.”
Lawyers believe thousands of minors could join the classes and continue to seek out victims victimized by AI CSAM.
NCMEC did not respond to Ars’ request for comment.
However, the group called on platforms, lawmakers, child safety organizations and law enforcement agencies to work together to address the “increasing urgency for coordinated action.”
In March, NCMEC warned A “sharp increase” in “reports of generative AI” (GAI) in 2025. According to NCMEC, more than 1.5 million CyberTipline reports were made last year, which “shows a link between QAI and child sexual exploitation.” Unfortunately, in more than 133,000 cases, NCMEC “did not obtain sufficient data to determine how the technology was used.”
That report didn’t mention X or xAI, but that suggests it’s likely common for AI companies to be reluctant to share information about AI CSAM that police could use to make arrests. For another example, NCMEC noted that Amazon AI services provided the vast majority of tips (1.1 million), and none of those tips provided “actionable information” that law enforcement could use to identify criminals.
As investigations into the harm AI firms do to children intensify, advocates hope firms will adjust models to avoid all the hype. The girls who sued Xi claimed it was the only remedy, “because if you have a model that allows any sexual or offensive content, there’s no way to prevent that model from creating content that involves minors.”
In a press release, one of the attorneys representing the minors, Annika K. Martin, criticized xAI and Stability AI for allegedly building models “capable of producing profoundly fraudulent CSAM” with “complete disregard for the devastation they knew would follow.”
“AI-generated CSAM is a societal scourge that touches every community and every demographic,” Martin said. “The scale of the damage is staggering, and the companies whose products enable it must be held accountable.”
