Vidu S1

Vidu S1 is a real-time interactive AI avatar platform driven by a streaming video generation model, built for enterprise product teams that want to bring digital humans into their products.

Instead of settling for stiff, scripted characters, teams can shape custom personas and take fine-grained control over voice, while bidirectional perception lets the avatar pick up on user input and react naturally during live conversations.

The platform is engineered to run efficiently over WebRTC media transport and WebSocket control channels, delivering end-to-end low latency so interactions feel smooth and responsive. From prototyping to evaluating digital human experiences, Vidu S1 gives teams a practical foundation for real-time, human-like engagement.
