Plain-Language Brief

Researchers studied AI-generated explicit content on 4chan and found a shift from targeting celebrities to non-celebrity individuals (55.8% vs. 4.7% in prior studies). Open-source models are widely used, with Stable Diffusion and Wan generating the majority of images and videos. The ecosystem is driven by a small group of active producers who influence community dynamics.

What the Document Says

• The study examines AI-generated explicit content (SNEACI) in the wild on 4chan.
• Non-celebrity individuals now account for 55.8% of targets, compared to 4.7% in previous studies.
• Open-source models dominate production, with Stable Diffusion family generating 42.7% of images and Wan generating 66.5% of videos.
• Thousands of shared fine-tuned models and accessible tutorials facilitate the use of these models.
• The ecosystem is driven by a small cohort of active producers who shape community dynamics, target demographics, and disseminate technical knowledge.

Raw Abstract / Excerpt

AI nudification uses generative models to create synthetic non-consensual sexually explicit imagery (SNEACI) of real individuals. Prior work has examined dedicated nudification platforms and model repositories, finding that most targets are female celebrities. However, the anonymous content community, where SNEACI is actively requested, generated, and exchanged, remains unexplored. In this work, we present a large-scale study of AI nudification in the wild, identifying 24,105 SNEACI items. We find a significant shift in target demographics: non-celebrity individuals now account for 55.8% of targets, compared to only 4.7% in prior studies, indicating that AI nudification has expanded from targeting public figures to increasingly harming individuals within users' own social circles. Meanwhile, open-source models dominate production, with Stable Diffusion family generating 42.7% of images and Wan generating 66.5% of videos, all driven by thousands of shared fine-tuned models and accessible tutorials. Yet the ecosystem runs on a small cohort of active producers, with the most prolific producing 780 items, drives community engagement, shapes target demographics, and disseminates technical knowledge that lowers barriers for new producers. Our work provides an empirical understanding of how AI nudification operates in the wild, revealing the mechanisms that sustain this ecosystem and highlighting the urgent need for interventions in platform governance, technical safeguards, and affected individual protection.
