ChatAnyone is an AI digital human generation tool developed by the HumanAIGC team, whose core function is to automatically generate digital human videos with upper body movements (including head rotation, gesture changes and expressions) from a single portrait photo and audio input. The project is based on the Hierarchical Motion Diffusion Modeling technique, and key features include:
- Multimodal inputs and outputs: Transforms still images with sound into motion video
- Motion Generation Capability: Supports head movements (e.g., nodding), 6 basic gestures (e.g., hearts, waving), and lip synchronization
- Professional-grade output: Supports up to 512 x 768 resolution, 30FPS video generation, and efficient rendering on NVIDIA 4090 GPUs
Compared with similar tools, it is characterized by focusing on the refinement of the dynamic details of the upper body, applicable to virtual image display, animation production and other technical scenarios. Currently the project focuses on technology demonstration, sharing the realization details through GitHub but not completely open source.
