Omnihuman AI

Omnihuman AI is a multimodal digital human generation framework developed by ByteDance. It can generate realistic dynamic digital human videos using only a single image. Supporting portraits, half-body, full-body figures, and diverse styles such as real humans and animations, it achieves millisecond-level lip-sync and audio-video linkage. It automatically generates natural expressions, eye movements and body motions based on speech semantics, with realistic emotional changes and physical dynamics. The model supports dual-person interaction, long video generation and 1080P HD output, driven directly by text or audio. With smooth and natural movements, it is ideal for virtual anchors, short videos, education, training and marketing, enabling efficient creation of high-quality dynamic digital human videos from static images.
