ByteDance Seed is the foundation-model research arm of ByteDance, the company behind TikTok, Douyin and CapCut. Formed in 2023 and led by Wu Yonghui, Seed ships the Doubao consumer assistant, the Skylark / Doubao LLM family, the Seedream image model and the Seedance video model. Seedance launched in early 2025 with two tiers: Seedance Pro (high-fidelity) and Seedance Lite (fast). The Pro tier targets advertising, e-commerce and film-style use cases, with longer durations, higher resolution and richer cinematic controls than Lite. ByteDance also expose Seedance through the Doubao API, the CapCut Pro creator suite and selected enterprise integrations.
Visit ByteDance Seed →Seedance Pro is a closed Diffusion Transformer operating on a 3D spatio-temporal Variational Autoencoder. The denoiser uses full 3D attention with bilingual text conditioning from ByteDance's Doubao / Skylark LLM family and optional image embeddings for first-frame, end-frame and subject-reference modes. The Pro tier is positioned for high-fidelity creative work and supports 5-10 second clips at 1080p / 24-30 fps with extension chains for longer sequences. Cinematic control vocabulary covers lens choice, camera moves and shot scale. Training uses a curated multilingual video corpus drawn in part from ByteDance's privileged access to TikTok / Douyin platform data, with synthetic dense bilingual captions and reward-model post-training tuned for aesthetic quality and prompt fidelity. Public independent benchmarks (Artificial Analysis, etc.) consistently rank Seedance Pro in the top tier of Chinese video models alongside Kling v3.
