Nexus Mods requires AI disclosure over outright ban, sets 60-day compliance window

Published 4 Nov 2026 · Games Atlas Editorial · Policy Change · Companies: Valve, itch.io

Games Atlas summary: Nexus Mods will require creators to disclose AI use in every uploaded mod. Nexus Mods rejects an outright ban, citing the difficulty of enforcing one. Existing mods get a 60-day grace period ending January 2, 2027, before restrictions apply. The policy mirrors a disclosure-first model other UGC platforms are already adopting.

Disclosure over ban reflects an enforcement calculus

• Folmann argues a ban would discourage disclosure without removing AI from modding.
• "An outright ban will not eliminate AI from the modding process but will prevent people from mentioning its use." - Victor Folmann, CEO, Nexus Mods
• Mods tagged as AI-assisted must now include a public explanation of their AI use.

Permission gaps remain unresolved for derivative and forked mods

• Nexus Mods has no rule yet for mods built on other authors' AI-assisted work.
• New permission options for AI training, forks and derivatives default to ask-me mode.
• "There are some details we still need to figure out and work through, especially when it comes to existing licences, forks, and how permissions apply to different versions of a mod." - Victor Folmann, CEO, Nexus Mods

Industry converges on disclosure-first moderation over blanket bans

• Steam requires AI-content disclosure on store pages without barring AI-made games.
• SteamDB, now owned by Nexus Mods parent Chosen, tags games using those disclosures.
• Itch.io deleted multiple terabytes of self-described AI slop, yet still allows generative AI uploads.

What to watch

• Existing mods must comply by January 2, 2027, or face account restrictions.
• Nexus Mods says permission and derivative-mod rules will take longer to finalize.

What this means

• For Publishers & Developers: Add AI-use disclosure fields to official mod tools and first-party UGC upload flows.
• For Investors & VC: Add AI-provenance labeling and derivative-permission controls to diligence on UGC and modding platforms.
• For Service Vendors: Pitch AI-content detection and moderation tooling to UGC platforms rolling out disclosure enforcement.
