About SadTalker

SadTalker is an open-source AI system for generating realistic talking head videos from a single portrait image and optional short audio. It delivers accurate lip-sync, expressive facial motion (head pose, eye blinks, emotion), and supports both static photo driving and dynamic video-driven modes. Built on modules like Audio2Exp and MetaAudio2Face, the v2.0 release improves 3D motion quality, identity preservation, and reduces artifacts. A free web demo (no login) and a fully open GitHub implementation with downloadable checkpoints and Colab support make it accessible to creators, researchers, and developers.
