After widespread protests from artists in December 2022, Epic's portfolio platform ArtStation introduced a "NoAI" label that artists can apply to their work to signal they do not want it used in AI training datasets. Epic also updated its terms of service to commit that it will not use or license any ArtStation content — labeled or not — for AI training purposes.

Following a mass protest in which thousands of artists posted black squares to ArtStation in opposition to AI-generated art appearing on the platform, Epic rolled out the NoAI tag in late December 2022. The tag adds a metadata signal to the artist's portfolio page. ArtStation's terms of service were updated to prohibit scraping or mining of NoAI-tagged content for AI training. Critically, the tag is opt-in rather than opt-out by default — meaning artists must actively apply it, which was a point of ongoing criticism from the community. However, Epic went further than the tag alone: its terms of service now state that Epic will not use any user content on ArtStation — regardless of whether the NoAI tag is applied — as training data for generative AI programs or in the development of generative AI tools. Community response was mixed; many appreciated the commitment but noted that significant amounts of ArtStation artwork had already been scraped for AI training data before the policy existed, including by the dataset used to train Stable Diffusion.
