Prompt
[Low-angle tracking shot] A small fox trots nimbly through the forest. Sunlight filters down through gaps in the leaves. The fox stops, alertly perking up its ears. [Cut to] Spotting danger, it quickly turns and flees, with the camera chasing after the fox as it dodges through the dense woods.

Pozadí
O ByteDance Seed
Založeno 2023 · Beijing, China
ByteDance Seed is the foundation-model research arm of ByteDance, the company behind TikTok, Douyin and CapCut. Formed in 2023 (initially called 'Doubao Foundation Model' / 'Skylark', renamed Seed in 2024), the team is led by Wu Yonghui and ships the Doubao consumer assistant, the Skylark / Doubao LLM family, and the Seedance and Seedream video and image models. Seedance launched in early 2025 with two tiers: Seedance Pro for high-fidelity creative work and Seedance Lite for fast, high-volume generation. The lite tier targets short-form social workflows on TikTok-adjacent surfaces and CapCut integrations, where latency and cost are paramount.
Seedance Lite is the speed-tier variant of ByteDance's Seedance text-to-video and image-to-video model. It is a closed Diffusion Transformer operating on a 3D spatio-temporal latent, distilled from Seedance Pro via consistency-style training and quantization to compress the diffusion sampler into far fewer denoising steps. Conditioning uses a bilingual Chinese/English text encoder (based on ByteDance's Doubao / Skylark LLM family) and image embeddings for first-frame conditioning. Output is 5-second clips at 720p / 24 fps. The lite tier is designed to be deployed at very high volume across ByteDance's consumer surfaces (Doubao app, CapCut, TikTok creator tools in China) where per-clip cost matters more than maximum fidelity. The base Seedance corpus is closed but ByteDance hold privileged access to large-scale TikTok / Douyin video data which is presumed to inform training.
