Nexus Mods makes AI-use disclosure mandatory for new mod uploads

Nexus Mods, the largest repository for PC game mods, will require authors to disclose whether AI played a part in their work when uploading new mods. According to The Verge, site owner Victor "Foledinho" Folmann announced the change in a wide-ranging post about how the platform plans to handle AI-generated content.

What mod authors will have to declare

Under the new policy, every new mod upload must state whether AI was involved in creating it. Mods carrying an "AI-assisted" tag face an additional requirement: the author must publish an explanation of where in the creation process AI was applied and what it was used for. Tags indicating AI involvement will also be given more visibility on mod pages.

Existing mods are not exempt. Mod authors have a 60-day grace period, ending on January 2nd, to bring their current uploads in line with the requirements. After that date, The Verge reports, Nexus Mods will begin enforcing the rules.

A labelling approach instead of a ban

Folmann describes the platform's position as backing human creativity, but he has ruled out prohibiting AI-generated mods entirely. His reasoning, as laid out in the announcement: AI now appears at nearly every stage of creative work, from autocompleting scripts to generating textures, voices and complete assets, which makes it hard to define a clear line between acceptable and unacceptable use.

In his view, a ban would not remove AI from modding — it would simply discourage people from admitting they use it. The site prefers the opposite outcome: AI usage out in the open, clearly labelled, and governed by rules the platform can actually enforce.

Mods will not be used to train AI

The announcement also addresses a fear common to creative communities. Folmann states that Nexus Mods will not use mods to train AI models, and will not sell or license them to any party that intends to do so. The platform is additionally working on clearer controls around how mods can be reused by others, plus stronger attribution when a mod builds on another author's work with the appropriate permissions.

Changes to how mods are discovered

The site is also reworking its Recently Added section. The problem, according to Folmann, is that some authors upload large batches of mods at once, pushing everyone else's work down the page. He notes this is not strictly an AI issue, but it has become more visible as AI accelerates the pace of mod production.

The planned fixes include limits on how many mods from a single author appear at one time, and tighter restrictions on uploads from newly created accounts. Separately, Nexus Mods is introducing controls that let users hide AI-generated content on game pages and the homepage, with similar filtering in search described as the next step.

Why it matters

Nexus Mods sits at the centre of the PC modding ecosystem, so its policy decisions carry weight well beyond a single site. The move illustrates the dilemma facing creative platforms as generative AI becomes embedded in everyday workflows: prohibit it and risk driving usage underground, or require disclosure and give the community the information to judge for itself. Nexus Mods has chosen the second path, pairing mandatory labelling with a commitment not to feed mods into training data and user-side tools to filter AI content out. For mod users, the practical effect arrives within two months: every mod page should make clear whether AI was involved, and those who prefer to avoid AI-generated content entirely will soon have the controls to do so.
