Vidu S1

Vidu S1 is the 生数科技 / Shengshu Technology product discussed by 张金涛 / Zhang Jintao in 快一点！再快一点！快到世界能实时生成｜和生数科技张金涛聊：Vidu S1、推理加速、实时交互视频. The source presents it as a Real-Time Interactive Video Generation product: a user can upload a character image, choose or clone a voice, and speak with the generated character while facial expression, motion, and body language respond live.

The source-scoped technical claim is that S1 supports long streaming generation at 540P and roughly 25 to 42 FPS, with the team prioritizing real-time response before maximum image quality. Zhang says S1 can also use video understanding, including camera, game-screen, desktop, or coding-screen input, so a virtual character can react to what the user is seeing.
