ByteDance Seedance: How China's Video-Gen Model Turned the Tide

ByteDance's Seedance 2.0 model has achieved unprecedented success in the market, with profit margins reaching 70-90%. According to the Volcengine MaaS platform, over half of its revenue for 2026 is expected to come from Seedance. This success is attributed to researcher Xing Yan, who advocated for training a model with 200 billion parameters, supported by team leaders. The architecture of Seedance 2.0 has been completely revamped compared to its predecessor, PixelDance, transitioning to a DiT-based framework that enhances performance. The core team remains small, consisting of over ten algorithm engineers.
