ComfyUI_LongCat_Avatar

LongCat_Avatar,an upgraded open-source framework for audio-driven human video generation.

Update

• use comfyUI whisper-large-v3 audio_encoders，offload lora to cpu
• 音频解码改成comfyUI内置单体模型方式，开启lora和cache的卸载，降低显存占用
• 部署节点，目前单人和双人测试通过，部分参数未严谨测试，请自行测试，有bug可以提issues或反馈给我的B站或小红书smthem账号
