CheckpointLoaderAdvancedMultiGPU

The CheckpointLoaderAdvancedMultiGPU node is used to load checkpoint models (complete diffusion models containing UNet, CLIP, and VAE components) with granular device control, allowing individual placement of each model component on different GPUs or devices.

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.

Inputs

Parameter Data Type Description
ckpt_name STRING The name of the checkpoint model to load.
unet_device STRING Target device for the UNet diffusion model component (e.g., 'cuda:0', 'cuda:1', 'cpu').
clip_device STRING Target device for the CLIP text encoder component (e.g., 'cuda:0', 'cuda:1', 'cpu').
vae_device STRING Target device for the VAE decoder/encoder component (e.g., 'cuda:0', 'cuda:1', 'cpu').

Outputs

Output Name Data Type Description
MODEL MODEL The loaded UNet diffusion model.
CLIP CLIP The loaded CLIP text encoder model.
VAE VAE The loaded VAE decoder/encoder model.
