Chinese video-sharing site Bilibili notified content creators on Thursday that they need to label AI-generated content to avoid misleading audiences, several days after short video platform TikTok sibling Douyin introduced similar rules. Bilibili has also outlined six other specific tag requirements for users when uploading videos, including “risky behavior”, “rational consumption”, and “personal opinion”, with the policy set to take effect on Sept. 20. If a video meets the criteria for multiple creator declarations, the platform emphasized that the AI tag should be given the highest priority in such cases due to the ability to add tags currently being limited to one tag per video.
