Anyone who downloads mods from Nexus Mods will soon be able to see when AI was used to make them, and hide those mods if they prefer. The site, one of the biggest mod libraries for PC games, now requires authors to declare AI use on new uploads. It will not ban AI-made mods.
Nexus announced the rules on 3 November and is allowing a 60-day grace period for the new requirements, ending on 2 January 2027. After that, mods that are untagged or non-compliant go to the site’s Trust & Safety team, and authors who ignore staff notices can face warnings, account restrictions or removal.
Nexus’s policy page sets out three labels: AI Generated Content, for mods whose core work came from AI tools such as generated code, synthetic voice lines or textures; AI Media, for AI thumbnails, banners, videos or descriptions; and AI Assisted Content, for human-led mods where AI played a supporting part, such as texture upscaling or audio clean-up.
A mod marked AI Assisted must say on its main page which tools were used and exactly which files, assets or code came out of them. Nexus may ask the author for development history and for proof they understand their own code, and it can replace the label if the claim isn’t backed up. Authors must update the statement when later versions add AI parts.
The policy also adds permission settings for AI training and for forks or parallel versions, defaulting to “Ask Me” on every hosted file, old mods included. That bars anyone from using a mod’s assets to train generative AI, or from hosting a fork, without the author’s written permission. Existing licences such as GPL still apply. Forks and derivative works must credit the original creators and link back to the source mod.
Site owner Victor Folmann wrote that Nexus is “pro-human creativity” but won’t ban AI mods outright, because AI now touches everything from code autocompletion to textures and a ban would only stop people mentioning it. The Verge reported that Nexus will not use mods to train AI or license them to anyone who does, and that tools to hide AI-generated content are arriving on game pages and the homepage, with search next.
The same update tightens the Recently Added list, which some authors flood by uploading many mods at once, and puts stricter limits on uploads from new accounts. Nexus also says it may ask for source code when it has safety concerns, and can decline to host a file if the code isn’t provided.
