JoyAI-Echo is an open-source GitHub repository that provides long-horizon audio-visual generation and omnimodal world models for creating persistent stories and interactive worlds.
This paper presents JoyAI-Echo-1.5, a unified audio-visual generation system for long-form video and interactive worlds, using cross-shot memory and geometry-aware control to maintain coherence and persistence.
EchoWM introduces an open omnimodal world model that generates synchronized video, sound, music, and speech with continuous 6-DoF navigation for enterable generative media.
LongAV-Compass is a comprehensive benchmark for evaluating minute-long audio-visual generation across text, image, and video conditioning modalities, assessing quality, consistency, and alignment over extended temporal sequences.
