JD Open Source has released an open-source project called JoyAI-Echo. This repository includes two independent projects, each with its own environment and checkpoints.
Echo-LongVideo focuses on long-duration (multi-shot) audio-visual generation. It can generate videos up to approximately 5 minutes in length and utilizes paired audio-video memory banks to maintain continuity between shots.
Echo-WM is an omnmodal world model for generative media. It is characterized by its ability to evolve video, ambient sounds, music, and speech in response to continuous user navigation.
The project provides model weights on Hugging Face and also supports a ComfyUI plugin. Related papers and project pages have also been released.
