CheckpointLoaderNF4MultiGPU

CheckpointLoaderNF4MultiGPU wraps the NF4 checkpoint loader from ComfyUI_bitsandbytes_NF4 so you can pick the execution device when working with 4-bit Quantised diffusion checkpoints.

Inputs

All base parameters from CheckpointLoaderNF4 are retained. The MultiGPU wrapper adds one optional field:

Parameter	Data Type	Description
device	STRING	Device that should own the loaded NF4 checkpoint (GPU id or cpu).

Outputs

Outputs are identical to the upstream NF4 loader (UNet/CLIP/VAE tuple). The only behavioural change is the explicit device placement. |
