MOSS-Image for ComfyUI

English | 中文

Native MOSS-Image loaders for ComfyUI that output standard MODEL, CLIP and VAE objects, so you can use ComfyUI's own sampling, guidance and memory management nodes.

Forked from OpenMOSS/MOSS-Image (the comfyui/ subtree), republished as a standalone custom node.

Installation

Option 1: Comfy CLI / ComfyUI-Manager (recommended)

comfy node install comfyui-moss-Image

Or search for comfyui-moss-Image in ComfyUI-Manager → Custom Nodes → Install.

Option 2: Manual git clone

cd ComfyUI/custom_nodes
git clone https://github.com/wanaigc/comfyui-moss-Image.git

Restart ComfyUI. The plugin uses ComfyUI's bundled Python dependencies, no extra install step is required.
