As of now, the U.S. Copyright Office is still publicly pointing to the May 2025 pre-publication version of Copyright and Artificial Intelligence, Part 3: Generative AI Training, not to a formally effective final AI-training rule. Even so, the policy debate has become much more operational over the past year. If commercial model training continues to rely on platform datasets, open-web scraping and third-party licensing, questions about data provenance, authorization chains and the execution of rightsholder opt-outs are no longer abstract talking points. They are turning into concrete compliance issues that companies may be asked to explain.
For short-video platforms, social media services and other UGC-heavy businesses, the real pressure is not just whether a front-end “no AI training” option exists. It is whether that instruction can actually travel through scraping controls, API outputs, data-sharing arrangements and downstream development workflows. The Copyright Office has not publicly issued a finalized mandatory technical rule, but the direction is already clear: a platform that enables AI training access while struggling to show how opt-outs, license scope and protected-content filtering are implemented will have a harder time presenting itself as a neutral conduit in future copyright disputes.
