About the tool (excerpt from the public listing)
Vidu S1 is a streaming video generation model for real-time interactive digital humans. Different from offline-rendered text-to-video models, it can generate videos in real-time during the conversation, enabling the character to interact with the user in near real-time. The main advantages of this model include supporting unlimited-length interactions, near real-time response, multi-modal perception, high-resolution output, etc. The product is positioned as a commercial-grade and can be widely used in fields such as social, e-commerce, games, and education. New users can get 1000 free trial credits without SDK lock-in.
