ByteDance Deploys Seedance 2.0 Video Model to CapCut's 736M Users as OpenAI Shutters Sora

ByteDance has integrated Seedance 2.0, its multimodal video generation model, into CapCut for paying users across multiple global regions, reaching a platform with approximately 736 million monthly active users. The model supports text, image, audio, and video inputs, generates synchronized audio-video output in a single pass including multi-shot sequences, and ranks in the top two on Arena AI and Artificial Analysis video leaderboards, with Alibaba's HappyHorse-1.0 as its closest competitor. Simultaneously, OpenAI is discontinuing the Sora app and API after daily active users fell below 500,000 and operating costs reached an estimated $1 million per day. The contrast illustrates a broader market shift where Chinese developers are accelerating video model releases while U.S. consumer video products retreat.
