What did Nexus Mods announce?
Nexus Mods published a new AI policy on 3 November 2026. From that day, anyone uploading a new mod must declare whether generative AI was used. Existing mods have until 2 January 2027 to meet the same rules.
The announcement is a long site post titled "AI-Generated Content on Nexus Mods". It is signed by Victor Folmann, who runs the site under the name Foledinho. By the morning of 4 November, the post had drawn 818 comments, a sign of how divided the community is.
The platform is large. Wikipedia records 73.3 million registered users, 4,581 supported games and more than 22.5 billion file downloads as of April 2026. Most mods are free, and authors earn Donation Points for their work.
Nexus Mods has changed hands recently. Founder Robin Scott announced in June 2025 that he was selling the site after 24 years, citing the pressure of running it. The new rules are also published as a separate help-centre document, so authors can read the full policy rather than rely on a summary.
The change is narrower than a ban and wider than a nudge. AI tags already existed before this week, and authors could choose between an AI-generated label and an AI-assisted one. What was missing was a mandatory declaration, a public explanation of how AI was used, and any penalty for leaving the field blank.
How does the new AI labelling system work?
The policy splits AI use into three labels, and each one carries different obligations. AI-Generated Content means the core work came from AI, such as generated code, synthetic voice lines, textures, text or scripts. AI Media covers promotional material outside the game files, including thumbnails, banners, videos and descriptions.
The third label is AI-Assisted Content. It applies to human-led mods where AI played a supporting role, such as texture upscaling, audio cleanup or early concept art. That label is the one with the strictest paperwork.
Authors who use the AI-Assisted tag must publish an itemised explanation on the mod page. They need to name the specific tools, software or models they used. They must also state exactly which AI outputs ended up in the final mod.
The policy adds two further tests. Authors should be able to show evidence of human-led design, such as project files or version control history. They may also be asked to explain how their code works during a moderation dispute. If that evidence is missing, moderators can reclassify the mod.
Disclosure is now part of the upload form, not an optional field. Existing mods see a persistent prompt when edited and a dismissible notice on the My Mods page. AI tags will also appear directly after adult-content tags, so readers see them before they download.
Authors must update their statements when an update adds new AI components. The rule is meant to stop a mod from being labelled once and quietly changed later, which is one of the gaps the old tag system left open.
The policy also gives readers controls, not just labels. AI filters are now available on game pages and the homepage, with search promised next. Authors who upload many files at once may be limited in the Recently Added feed, and brand-new accounts face tighter upload restrictions.
What changes for permissions, forks and credit?
The second half of the policy concerns control over a mod after it is published. Nexus Mods is adding explicit permission settings for AI training and tool use, and for forks or parallel versions. Both settings default to "Ask me" across all hosted files, including legacy mods.
"Ask me" is stronger than it sounds. It bars anyone from using a mod's assets for AI training, fine-tuning or dataset building without written permission. It also covers automated AI editing, synthesis and generative workflows. The rule applies to meshes, textures, scripts, audio, text and source code.
Forking gets a similar standard. Hosting a fork, variant or parallel version now requires clear authorisation from the original creator. That is unless the mod page already allows forks, or an open licence such as GPL3 requires derivatives to be permitted.
Copyleft licences override the platform default. If a licence legally permits derivative works, Nexus Mods says its moderators will honour those terms rather than the site's "Ask me" setting. The policy also covers inactive authors: if someone cannot be reached, the default stays in place.
There is one narrow exception. If an author's existing permissions already allow reuse but they never enabled forking, the site may treat them as unresponsive after six months of inactivity and a staff message. Existing parallel versions published before the policy will be reviewed case by case.
Attribution rules are tighter as well. Any derivative work must credit every creator in the chain and link back to the original mod. Assets taken from another site need a working link to that source page. The aim is to make credit verifiable rather than a courtesy.
None of this resolves the hardest case: a mod that mixes original work, a licensed asset pack and one AI-generated texture. The policy asks for credit on every layer. Proving where one creator's work ends and the next begins is left to moderators.
Not every detail is settled. Folmann admits that licences, forks and different versions of the same mod still need work. He says the permission changes will take longer to deliver than the disclosure rules, because a rushed version could create new disputes.
Why won't Nexus Mods ban AI mods?
The central argument is that a ban would hide AI use rather than remove it. Folmann writes that AI is used across the whole creation process, from autocompletion to full asset generation. Drawing a clean line between acceptable and unacceptable use is therefore difficult.
His stated principle is simple: "We are pro-human creativity." The site says AI-generated mods remain welcome if they meet standards on permissions, transparency, presentation and conduct. It also promises not to train AI on hosted mods or license them to anyone who does.
Money is part of the calculation. Nexus Mods says mods carrying the AI-Generated Content tag received 2.13% of all Donation Points so far this year. That share is low enough that the site is not changing its reward rules for now.
The site gives two reasons for caution on rewards. Donation Points affect real earnings, so any change needs precision. Cutting payments for disclosed AI use would also give authors a motive to stay quiet, which is the opposite of what the policy wants.
Security is the policy's other major theme. Between November 2025 and October 2026, staff manually reviewed and cleared 3,164 uploads, more than four times the previous year's figure. Another 20,000 uploads were quarantined for checks, 12 times the prior year.
Nexus Mods can request source code when it suspects hidden behaviour in a mod. Authors are not obliged to hand it over. The site can, however, decline to keep hosting a file if the concern cannot be resolved.
The policy is candid about enforcement limits. Folmann writes that identifying AI-generated content is "by no means an exact science". Much of the work will rely on manual moderation and reports from users, and some mistakes are expected.
The comment thread shows why a compromise was likely. Video Games Chronicle reports that some readers wanted an outright ban, and complained about AI thumbnails crowding game pages. Others argued that generative tools had made modding more accessible and felt the new rules targeted them.
Folmann addressed that split directly. He wrote that he does not expect everyone to agree with every decision, and that the policy will keep changing as the tools change. The post treats the new rules as a starting point rather than a settlement.
Why are game storefronts moving on AI now?
Nexus Mods was not alone on 3 November. itch.io, the indie storefront, added a "No AI" filter to its browse menu, search and other pages. Engadget measured the effect: the filter cut visible projects from more than 1.77 million to under 425,000.
itch.io has been deleting content as well as hiding it. The platform said on Bluesky that it had removed "a couple of terabytes of AI slop", as TechRaptor reported. Its quality guidelines already ban uploading excessive amounts of automatically generated content.
Valve moved on the same day, but for a different reason. It told developers that store and page reviews now take up to 12 business days, against the usual 3 to 5. The company cited "a significant increase in submissions" in recent months.
Valve's fix targets re-reviews rather than AI content. Developers must now run a build through Steam for at least five minutes before submitting it. They also need achievements ready and any required redistributables, such as DirectX or Visual C++, confirmed.
Steam still has no way to filter AI games out of the store. It requires developers to disclose generative AI use, but discovery tools have not caught up. That contrast explains why itch.io's filter drew so much attention this week.
The common thread is volume. Cheaper tools have shortened the time between an idea and a publishable build, and storefronts are absorbing the result. Moderation teams, review queues and recommendation algorithms were sized for a slower pace.
Each platform is choosing a different lever. Nexus Mods is betting on disclosure and permissions. itch.io is betting on filtering and deletion. Valve is betting on process fixes that reduce wasted reviews. None of them has tried a blanket ban.
The incentives differ as well. Nexus Mods depends on volunteer authors, so it needs their cooperation for labels to mean anything. itch.io and Steam deal with strangers publishing finished products, which makes filtering and review capacity the practical tools.
What could go wrong before 2 January 2027?
Self-reporting is the weakest link. An author who wants to hide AI use can simply tick "no" and hope nobody checks. Nexus Mods knows this and says reports from users will carry much of the enforcement load.
False positives are the mirror problem. Texture upscaling and audio cleanup are common in large mod packs, and both now require an itemised disclosure. A solo author fixing old assets may face paperwork that feels disproportionate to the change.
Legacy mods create inconsistency. The policy says existing permissions will not be reset, so older uploads keep whatever terms they had. Two similar mods may therefore carry different AI and fork rules depending on when they were published.
The permission defaults could also freeze collaboration. A mod whose author left the community years ago stays on "Ask me" indefinitely. Fixes and compatibility patches then depend on the original author reappearing, unless a licence overrides the default.
"AI Media" is the label most likely to cause arguments. The policy lists four thumbnail scenarios and calls three of them gray zones. AI text overlays, upscaled screenshots and generated art for code-only mods are all left to case-by-case judgment.
Enforcement capacity is the final unknown. The site has promised warnings, restrictions and removal after 2 January. It has not published staffing numbers for the Trust and Safety team that will handle the backlog.
The practical workload varies by author. Someone with a dozen texture packs can update a dashboard prompt in an afternoon. Someone maintaining hundreds of files across several games faces a much longer audit, especially where AI was used for a single texture pass.
The policy does promise a warning before punishment. Authors will be notified and asked to fix missing disclosures or permission settings. Only continued failure after a staff message leads to restrictions or removal, which gives dormant authors a chance to respond.
What should mod authors and players watch next?
The first test is compliance volume before 2 January 2027. Every hosted mod falls under the deadline, and the site has promised referrals for non-compliant files rather than an automatic sweep.
The second is the permissions rollout. Nexus Mods has not given a date for the AI training and fork settings, only a commitment to get them right. How those settings interact with GPL and Creative Commons licences will matter to large projects.
The third is search. Content filters for AI mods are live on game pages and the homepage, with search promised next. If search filtering works, it may do more to shape what players see than any tag ever did.
Donation Points remain under review. A 2.13% share is small today, but the site says it will keep monitoring. Any future change to rewards would be a stronger signal than disclosure alone.
For players, the practical change is simple. Mod pages will carry clearer AI labels, and a filter can hide them. For authors, the burden is evidence: name the tools, describe the outputs, and keep the receipts.
