💡 The paper introduces Vidu S1, a real-time interactive video generation model that enables voice-controlled digital character animation with high frame rates on consumer hardware. The model addresses the problem of generating high-quality, real-time video content that can be controlled by users through voice instructions. To achieve this, the authors employ TurboDiffusion and TurboServe, which allow Vidu S1 to produce 540p videos at up to 42 frames per second on regular consumer GPUs. The model supports infinite-length video generation without visual distortion and allows users to upload custom images and choose different voice tones for personalized experiences. The results show that Vidu S1 achieves the best performance across all test metrics while meeting real-time inference requirements, demonstrating its effectiveness in generating high-quality, interactive video content. Overall, the paper presents a significant contribution to the field of video generation, enabling real-time, voice-controlled, and personalized video experiences.
