Nexus Mods requires AI disclosure for new uploads

Nexus Mods hosts mods: community-created additions and changes to games. Creators can upload their work, while players can find and download mods for a range of games, including Skyrim Special Edition, Cyberpunk 2077 and Stardew Valley.

Authors uploading new mods to the site must now declare whether they used AI. Mods tagged as AI-assisted must also include a public explanation of how and where it was used.

Authors have a 60-day grace period, from November 3 until January 2, 2027, to bring existing mods into compliance. The site says direct enforcement starts when that period ends. Staff will notify authors and ask them to fix missing disclosures or permission settings; continued failure to do so after notification can lead to moderation action, account restrictions, warnings or removal.

The site says it is not imposing a blanket ban on AI-generated mods, provided they meet its rules. It also says it will neither train AI on mods nor sell or license them to others for that purpose. Initially, identifying AI content will still rely heavily on manual moderation and user reports.

New permission options covering AI use and training are planned, alongside changes to search and content preferences. The new permissions will default to asking the author for consent, without resetting existing settings. Nexus says work on permissions and discovery will continue beyond the initial disclosure changes.
