Meituan releases LongCat-Video-Avatar, achieving state-of-the-art (SOTA) simulation performance in open source.

Meituan has released and open-sourced its state-of-the-art (SOTA) virtual human video generation model, LongCat-Video-Avatar. The model achieves significant breakthroughs in three key dimensions: motion realism, long video stability, and identity consistency. It natively supports audio-video joint generation and video continuation, and through innovative cross-segment latent space stitching technology, effectively solves the image quality degradation problem in long video generation, stably generating 5-minute high-quality videos.
