Revolutionizing Real-Time Interactive Video Generation with Vidu S1: Unleashing Dynamic AI Avatars

ShengShu Technology introduced Vidu S1 at the 2026 Global Digital Economy Conference, showcasing its advanced video foundation model that enables real-time interactive video generation. Vidu S1 allows users to control AI avatars through voice input during live interactions, creating a more immersive experience. The model supports 540P resolution at 25 FPS and enables the creation of personalized interactive characters from a single image, paired with customizable voices, all running on consumer-grade GPUs.
Unlike traditional offline video generation models, Vidu S1 offers real-time interactive video generation, allowing users to provide continuous voice input during conversations. The model processes voice input, conversational context, and visual context to generate and update video content in real time. It also enhances voice interaction by interpreting spoken input to generate synchronized lip movements, facial expressions, gestures, and full-body actions in real time.
Vidu S1 stands out for its unlimited-duration real-time video generation capabilities, using an autoregressive diffusion architecture to continuously predict and generate subsequent video content based on user input and conversational context. The model updates character expressions, movements, and actions in real time, enabling interactions to evolve continuously. It delivers 540P resolution at 25 FPS, optimized for natural and responsive conversations.
The model's efficiency is achieved through model acceleration techniques like TurboDiffusion and low-bit SageAttention, enabling real-time interactive video generation on consumer-grade GPUs. The system-level optimization with TurboServe ensures stable, low-latency real-time interactive video generation throughout extended interactions. Vidu S1 provides a technical foundation for applications like real-time video conversations, interactive livestreaming, AI companionship, interactive gaming, and XR experiences.
Vidu S1 simplifies the creation of interactive characters by allowing users to generate AI avatars from a single image, eliminating the need for character modeling and training. The model captures the character's identity, appearance, and visual style to create synchronized movements and expressions in real time. This streamlined workflow makes personalized real-time interactive characters more accessible.
With Vidu S1, AI video moves beyond pre-generated content to dynamic, responsive experiences where AI avatars can understand user input, respond in real time, and evolve continuously. The model opens up possibilities for applications like AI companions, interactive livestreaming, game NPCs, branded AI avatars, customer service, online education, and XR experiences. Vidu S1 expands the capabilities of video foundation models, paving the way for the next generation of interactive AI experiences.
