CheckpointLoaderSimpleMultiGPU

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.

Inputs

Parameter	Data Type	Description
ckpt_name	STRING	The name of the checkpoint model to load.
device	STRING	Target device for compute operations (e.g., 'cuda:0', 'cuda:1', 'cpu'). Selected from available devices on your system.

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.
