The debate around deepfakes, as illustrated by the recent backlash to explicit images on the X-owned chatbot Grok, has revolved around what platforms should do to block such content. Civitai’s situation is a little more complicated. Its marketplace includes actual images, videos, and models, but it also lets individuals buy and sell instruction files called LoRAs that can coach mainstream AI models like Stable Diffusion into generating content they were not trained to produce. Users can then combine these files with other tools to make deepfakes that are graphic or sexual. The researchers found that 86% of deepfake requests on Civitai were for LoRAs.
In these bounties, users requested “high quality” models to generate images of public figures like the influencer Charli D’Amelio or the singer Gracie Abrams, often linking to their social media profiles so their images could be grabbed from the web. Some requests specified a desire for models that generated the individual’s entire body, accurately captured their tattoos, or allowed hair color to be changed. Some requests targeted several women in specific niches, like artists who record ASMR videos. One request was for a deepfake of a woman said to be the user’s wife. Anyone on the site could offer up AI models they worked on for the task, and the best submissions received payment—anywhere from $0.50 to $5. And nearly 92% of the deepfake bounties were awarded.
Neither Civitai nor Andreessen Horowitz responded to requests for comment.
It’s possible that people buy these LoRAs to make deepfakes that aren’t sexually explicit (though they’d still violate Civitai’s terms of use, and they’d still be ethically fraught). But Civitai also offers educational resources on how to use external tools to further customize the outputs of image generators—for example, by changing someone’s pose. The site also hosts user-written articles with details on how to instruct models to generate pornography. The researchers found that the amount of porn on the platform has gone up, and that the majority of requests each week are now for NSFW content.
“Not only does Civitai provide the infrastructure that facilitates these issues; they also explicitly teach their users how to utilize them,” says Matthew DeVerna, a postdoctoral researcher at Stanford’s Cyber Policy Center and one of the study’s leaders.
The company used to ban only sexually explicit deepfakes of real people, but in May 2025 it announced it would ban all deepfake content. Nonetheless, countless requests for deepfakes submitted before this ban now remain live on the site, and many of the winning submissions fulfilling those requests remain available for purchase, MIT Technology Review confirmed.
