This article outlines the exploration and deployment of four major content platforms – Douyin, Kuaishou, Xiaohongshu, and Bilibili – in the field of artificial intelligence. Douyin gained popularity through AI-generated paintings and introduced Jianying, an AI-assisted video editing tool. Kuaishou developed the large model Kuaiyi and added an AI dialogue feature within their app. Xiaohongshu created an AI painting tool, later launching the "Moment" feature for one-click note image generation. Bilibili is currently testing an AI assistant for search functionality, which can intelligently summarize video content. All these content platforms are leveraging AI to assist in content creation, offering more engaging features to attract a wider range of creators.
