Nexus Mods makes AI disclosure mandatory on new mods but won't ban AI

Nexus Mods now requires every new mod upload to say whether generative AI was used, the site said in a news post on 3 Nov. It isn't banning AI mods, and The Verge and the site's help pages describe the same rules.

Nexus says AI-assisted mods need a public explanation of where AI was used, AI tags are shown more clearly, and authors get new permissions for AI training and forks that default to 'Ask me'. Players get content filters to hide AI work. Nexus says it won't train AI on mods or sell them. Existing mods have a 60-day grace period until 2 Jan 2027, after which the rules are enforced.

The company says AI-tagged mods earned 2.13% of Donation Points this year. It also says it manually reviewed 3,164 uploads between Nov 2025 and Oct 2026 and quarantined 20,000, twelve times more than before. For Australian modders the rules apply the same way, so tag uploads now.

Steam has been moving the same way, as Photite covered in Valve's AI visibility change.
