JoyAI-Echo is a Python framework for long-horizon audio-visual generation, producing coherent multi-shot videos up to ~5 minutes with paired audio-video memory banks, plus an omnimodal interactive world model (Echo-WM). It includes inference scripts, Gradio demos, and a ComfyUI integration, released for non-commercial research use.

Use cases

• generate minute-long coherent videos with consistent characters and voice
• build an interactive generative world model that responds to navigation
• create multi-shot stories with synchronized audio and video
• run conversational editing of generated video in real time
• research long-video diffusion and memory-based consistency

When to choose

• you need long-form (minutes) audio-visual generation with cross-shot consistency
• you want an omnimodal world model for interactive media research
• you work in Python with GPU inference and want ComfyUI support

When to avoid

• you need a commercially licensed video generation model (non-commercial only)
• you need short-clip fast generation without long-horizon memory
• you lack GPU resources for large diffusion transformer inference
