| # 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. | | |
