Nexus Mods, the largest mod hub for PC games, is making AI disclosure mandatory for new uploads. Mod authors will have to declare whether AI was used in their work, and players will get search filters to hide AI-assisted content. The site stopped short of an outright ban, arguing that a ban would only stop creators from talking about their use of AI.

What happened

Site owner Victor "Foledinho" Folmann announced the policy on November 5 in a broad post about AI-generated content on the platform. He describes Nexus Mods as "pro-human creativity," but says the site "won't introduce an outright ban on AI-generated mods." His reasoning is that AI is already part of modding "from script autocompletion to generation of textures, voices, and full assets," so a ban would only discourage creators from mentioning it.

Mods tagged as AI-assisted will need a public explanation of how and where AI was used. Authors of existing mods will see a persistent prompt in the upload form and a dismissible one on their My Mods page. The rules come with a 60-day grace period that started on November 3, 2026 and ends on January 2, 2027, after which enforcement begins.

Nexus is also working on permission settings that cover AI use and training, as well as forks and derivative mods. Those settings will default to "Ask me," so permission has to be granted rather than assumed. The site says it will not use mods to train AI and will not sell or license them to anyone doing so. The announcement also changes how the Recently Added section works, limiting how many mods one author can fill the feed with at once.

Key details

  • Platform: Nexus Mods, a PC game modding repository
  • Policy: Mandatory AI disclosure for new mod uploads; no outright ban
  • Existing mods: 60-day grace period, from November 3, 2026 to January 2, 2027
  • Player controls: Search filters to hide AI-made content, with AI-assisted mods requiring a public explanation
  • Permissions: New AI-use, AI-training and derivative-work settings, defaulting to "Ask me"
  • Still unconfirmed: The release date of the new permission options and the exact filter options. Reaction in the comments is divided, with some users arguing that allowing AI-made mods conflicts with the "pro-human creativity" stance.

What it means for developers

  • Disclosure is becoming the norm. Steam already requires developers to disclose generative AI content that players see, and Itch.io has added a "No AI" search filter. Tracking your AI use from the start will save you from scrambling when a storefront asks.
  • Keep a production log. Record which tools touched your code, art, voice or text, and when. A simple log makes it much easier to write an honest disclosure later.
  • Be specific about permissions. Nexus's "Ask me" default shows how clear licensing works for add-ons and plugins. If you release mods, expansions or asset packs, state plainly who may reuse, fork or extend your work.
  • Decide where your line is. Nexus says it is hard to separate acceptable AI use from unacceptable use, since autocomplete and full asset generation both count. Writing down your own policy helps you answer player questions consistently.
  • Expect filters. Players are starting to exclude AI content on purpose. Be clear on store pages about what is generated, so you do not lose audiences who want to avoid it, and so you do not look evasive to those who do not mind.
