Live Avatar is an advanced real‑time avatar generation framework designed to transform audio input into lifelike digital characters with exceptional fluidity and precision. Developed by researchers at Alibaba, it uses a powerful 14‑billion‑parameter diffusion model to produce high‑fidelity avatar videos that respond instantly to speech and maintain consistent motion across long sequences. The system supports infinite‑length streaming through a block‑wise autoregressive architecture, enabling avatars to perform continuously for over 10,000 seconds without quality degradation Hugging Face. Live Avatar overcomes limitations found in traditional diffusion‑based video models by delivering stable, coherent animations and eliminating long‑horizon inconsistencies. Its optimized pipeline achieves real‑time performance at up to 20 FPS on high‑end GPUs, making it suitable for interactive applications such as virtual presenters, digital assistants, and live content creation. With an efficient algorithm–system co‑design, Live Avatar offers creators and developers a reliable way to generate expressive, responsive avatars that enhance communication and storytelling in dynamic environments.
