The CheckpointLoaderSimpleMultiGPU node is used to load checkpoint models (complete diffusion models containing UNet, CLIP, and VAE components) with device selection capability, enabling users to specify which GPU or device should be used for model execution.
This node automatically detects models located in the ComfyUI/models/checkpoints folder, and it will also read models from additional paths configured in the extra_model_paths.yaml file. Sometimes, you may need to refresh the ComfyUI interface to allow it to read the model files from the corresponding folder.
