Earlier this week, some people on X began replying to photos with a very specific kind of request. “Put her in a bikini,” “take her dress off,” “spread her legs,” and so on, they commanded Grok, the platform’s built-in chatbot. Again and again, the bot complied, using photos of real people—celebrities and noncelebrities, including some who appear to be young children—and putting them in bikinis, revealing underwear, or sexual poses. By one estimate, Grok generated one nonconsensual sexual image every minute in a roughly 24-hour stretch.

Although the reach of these posts is hard to measure, some have been liked thousands of times. X appears to have removed a number of these images and suspended at least one user who asked for them, but many, many of them are still visible. xAI, the Elon Musk–owned company that develops Grok, prohibits the sexualization of children in its acceptable-use policy; neither the safety nor child-safety teams at the company responded to a detailed request for comment. When I sent an email to the xAI media team, I received a standard reply: “Legacy Media Lies.”

Musk, who also did not reply to my request for comment, does not appear concerned. As all of this was unfolding, he posted several jokes about the problem: requesting a Grok-generated image of himself in a bikini, for instance, and writing “🔥🔥🤣🤣” in response to Kim Jong Un receiving a similar treatment. “I couldn’t stop laughing about this one,” the world’s richest man posted this morning sharing an image of a toaster in a bikini. On X, in response to a user’s post calling out the ability to sexualize children with Grok, an xAI employee wrote that “the team is looking into further tightening our gaurdrails [sic].” As of publication, the bot continues to generate sexualized images of nonconsenting adults and apparent minors on X.

AI has been used to generate nonconsensual porn since at least 2017, when the journalist Samantha Cole first reported on “deepfakes”—at the time, referring to media in which one person’s face has been swapped for another. Grok makes such content easier to produce and customize. But the real impact of the bot comes through its integration with a major social-media platform, allowing it to turn nonconsensual, sexualized images into viral phenomena. The recent spike on X appears to be driven not by a new feature, per se, but by people responding to and imitating the media they see other people creating: In late December, a number of adult-content creators began using Grok to generate sexualized images of themselves for publicity, and nonconsensual erotica seems to have quickly followed. Each image, posted publicly, may only inspire more images. This is sexual harassment as meme, all seemingly laughed off by Musk himself.
