The core decision: disclosure instead of prohibition
Nexus Mods says AI now shows up at almost every stage of making a mod. Its announcement lists script autocompletion, textures, voices and complete assets. The company argues that this makes a clean line between acceptable and unacceptable use hard to draw. It also warns that "An outright ban will not eliminate AI from the modding process but will prevent people from mentioning its use."
Nexus frames the new position as being "pro-human creativity." AI-generated mods are welcome as long as they meet criteria on permissions, transparency, presentation and conduct.
This is a policy bet. Bans are easy to announce but hard to enforce, and they can push people to hide AI use. Critics will say disclosure alone doesn't answer concerns about consent, labor and creative credit. Some coverage of Nexus's earlier AI tagging rules has made that point, including a PC Gamer piece that said the site is still "playing softball." Nexus says it expects not everyone to agree with its choices and will keep adjusting them.
What changes for mod authors
- New uploads: Disclosure is mandatory from November 3. Authors must declare whether AI was used in their work.
- AI-assisted mods: Nexus is adding a requirement for a public explanation of how and where AI was used. The aim is to give downloaders more than a bare tag.
- Tag placement: AI tags on mod pages will be more prominent. They will appear immediately after adult-content tags.
- Existing mods: Authors will see one of two prompts. One is persistent and appears when editing a mod in the upload form. The other can be dismissed and appears on the "My Mods" page.
- Grace period: The 60-day grace period runs from November 3, 2026 to January 2, 2027.
- Enforcement: Direct enforcement of the rules starts once the grace period ends on January 2, 2027. Authors will be notified and asked to fix missing disclosures or permission settings. Continued failure to update a mod after a staff notification will bring moderation action, account restrictions, warnings or removal.
The three tags, and why the choice matters
Nexus's published File Submission Guidelines already define the tag categories. They say new rules on AI usage, disclosure and permissions go live on January 2, 2027.
- AI-Generated Content: AI-generated code, user interface elements, voices, dialogue, translations, music and in-game assets.
- AI Media: AI promotional art, thumbnails, videos and mod page descriptions, meaning material outside the in-game content.
- AI Assisted: developer-led work with limited AI involvement. The guidelines list AI texture or audio upscaling and concept art that doesn't appear in the final mod.
The guidelines carry a warning. AI Assisted is the label for developer-led work with limited AI involvement. If a mod is primarily generated with AI, it should carry the AI-Generated Content tag, and moderators will apply that tag as needed. Authors who claim AI Assisted may have to show development history, such as project file or version-control commit history. They may also have to show real understanding of their code if the tag is disputed.
The guidelines also state that authors are responsible for checking the accuracy of claims on their mod page, including content generated or assisted by third-party tools such as generative AI. Authors who use AI in their workflow should keep their commit history and project files.
What changes for players
Nexus says it is refining its content preference tools. Players will be able to switch off AI-related content directly from game pages and the homepage instead of digging through settings. The next planned step is to bring those controls into search and into how mods are shown on game homepages. Inven Global's report on the announcement says the same: preference controls come first on game pages and the homepage, with search to follow.
Some coverage of the announcement describes these filters as fully live. Nexus's own post describes a staged rollout, and it gives no completion dates. The primary announcement also doesn't describe a dedicated filter for AI-generated promotional artwork. It discusses tags and preferences in general terms.
Nexus is also testing a limit on how many of one author's mods can appear in the "Recently Added" section. It is putting tighter restrictions on uploads from newly created accounts too. It says the first of these updates is coming soon.
Permissions, forks and AI training
Nexus is working on new permission options covering AI usage and training, as well as forks and derivative mods. Three points matter here:
- The new permissions will default to "Ask me," so permission has to be granted rather than assumed.
- Authors will be prompted to confirm their permissions actively during upload.
- Existing permissions will not be reset.
These permission changes are not arriving all at once. Nexus admits details are still unresolved, particularly around existing licences, forks and how permissions apply to different versions of a mod. The company says it would rather take longer than cause problems later.
Nexus also makes a separate commitment about its own conduct. It will not use mods to train AI and will not sell or license them to anyone who does. That promise is made at the platform level. It is distinct from the per-mod permission choices that authors will eventually be able to set.
Credit alone isn't enough, according to the submission guidelines. Accreditation doesn't replace explicit permission to upload or modify someone else's content.
Thumbnails, Donation Points and the gray areas
Nexus calls AI-generated thumbnails one of its toughest categories. It identifies three gray zones where reasonable people could disagree:
- A real screenshot with an AI-added title or text overlay.
- A real screenshot upscaled or enhanced with AI.
- Artwork for a script or framework mod that has nothing visual to show.
It is adding no new restrictions for those cases now. It wants to see how mandatory disclosure and improved tags and preferences work in practice first. It draws a hard line elsewhere. Any media that misrepresents what a mod does is against the guidelines, whether or not AI made it. AI images passed off as in-game screenshots will be treated as misrepresentation.
On rewards, Nexus says mods with the "AI-Generated Content" tag received 2.13% of all Donation Points so far this year. The company called that a "comfortably low percentage" and is not changing reward rules for now. It gives a practical reason. Penalizing authors financially for disclosing AI use could give them a motive to hide it, which is what the policy is trying to prevent.
The security angle
For a Windows audience, this may be the most practical part. Mods are executable or script-bearing content that runs on your PC, and Nexus says AI makes it much faster to write bespoke malicious code and hide it in mods. The company gives these figures for the period from November 2025 to October 2026:
- 3,164 uploads were manually reviewed and cleared by staff. That is more than four times the previous year's figure.
- 20,000 uploads were quarantined for further security checks. That is 12 times the previous year's total.
Where safety concerns or undisclosed behavior remain unresolved, Nexus may ask authors for source code. Authors aren't obliged to supply it, but Nexus may decline to keep hosting the mod if the concerns can't be resolved. These are Nexus's own figures and weren't independently audited.
Nexus's file guidelines already prohibit malware and restrict mods that connect to the internet, apart from tools where that is crucial to function. Disclosure doesn't make a mod safe. A transparent AI-assisted script can still be dangerous, and a non-AI mod can still be malicious. The tag is a signal about provenance, not a security guarantee.
Enforcement will be imperfect
Nexus is candid on this point. It says identifying AI-generated content is not an exact science, and that early enforcement will rely heavily on manual moderation and community reports. Some items may be tagged wrongly or missed. Players who spot a suspected violation are asked to report it.
That candor cuts both ways. Honest authors will tag accurately. Dishonest ones are the main target, and for now they may be caught mostly by other users.
What to do now
If you publish mods:
- Declare AI use on every new upload.
- Review existing mods using the "My Mods" prompt before January 2, 2027.
- For AI-assisted mods, write a clear public explanation of how and where AI was used.
- Keep development history that supports an AI Assisted claim.
- Check your permission settings, and expect new AI, fork and derivative options later.
If you download mods:
- Check the AI tags, which now sit right after the adult-content tags.
- Use the content preference controls on game pages and the homepage if you want less or no AI content.
- Report mods you believe are mislabeled.
- Treat any mod, AI-tagged or not, with normal security caution.
The bottom line
Nexus Mods has chosen labeling, permissions and moderation over prohibition. The concrete, dated changes are mandatory disclosure on new uploads, a grace period ending January 2, 2027, and more prominent tags. The permission defaults, search filters and fork rules are still promised work.
Whether disclosure satisfies players who want a ban, or authors who see AI as a legitimate tool, will only show up after enforcement begins in January.
