ByteDance Introduces New AI Model OmniHuman-1, Generating Realistic Full-Body Animations

ByteDance Launches OmniHuman-1 Model
On February 6, ByteDance researchers recently showcased an AI model capable of generating half-body and full-body videos from a single image and audio clip.
Full-Body Animation and Precise Synchronization
ByteDance stated that, unlike some deepfake technologies that can only generate facial or upper-body animations, OmniHuman-1 is capable of producing realistic full-body animations and can precisely synchronize gestures and facial expressions with voice or music.
Project Showcase and Applications
ByteDance posted several test videos on its OmniHuman-lab project page, including AI-generated TED talks and a speaking Albert Einstein. In a paper released on Monday, ByteDance highlighted that the OmniHuman-1 model supports various body types and aspect ratios, making the video output more natural.
Model Training and Performance
According to IT Home, ByteDance stated that the OmniHuman-1 model was trained using around 19,000 hours of human movement data, enabling it to generate videos of any length within memory constraints and adapt to different input signals. Researchers also mentioned that OmniHuman-1 outperforms other animation tools in terms of realism and accuracy.

Currently, the tool is not available for download or service.
Conclusion
ByteDance’s OmniHuman-1 model, which generates realistic full-body animations from images and audio, demonstrates the company’s innovation and breakthroughs in AI technology. OmniHuman-1 not only precisely synchronizes gestures and facial expressions but also supports different body types and aspect ratios, providing powerful technical support for generating natural video effects. Although the tool is not yet available for download or service, its performance in terms of realism and accuracy has already attracted widespread attention and anticipation.
