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