[CITIC Media] ByteDance in Sino-US AI Large Model Series 8: From Super App to Full-Stack AI, Ecosystem Loop Builds Long-Term Moat

English summary

Core view: ByteDance has completed its leap to an AI full-stack platform. Doubao ranks in the first tier of domestic general foundation models, Seedance establishes a leading position in global video generation, and pushes multimodal capabilities to extend toward world models and physical AI. Commercialization shows a clear echelon: Seedance realizes revenue first, Coding and edge-side take on mid-term incremental growth, and AI4S raises the long-term industry boundary. At present, Doubao has not yet formed a profitable loop covering high inference costs. We estimate annualized losses on the scale of RMB 10 billion, but its core value lies in seizing AI entry points and user mindshare through high-intensity upfront investment, and leveraging ByteDance's mature commercialization infrastructure to gradually convert traffic advantages into subscription, advertising, transaction, and MaaS revenue. ByteDance's truly scarce capability advantage is a compound loop where main-business cash flow supports computing power and model iteration, application scale accumulates users and data, and commercialization feeds investment back; single-point capabilities can be caught up, but the full-stack flywheel is harder to replicate, which will continue to consolidate ByteDance's core competitive position in the industry's contraction.
