# UNETLoader - ComfyUI Built-in Node Documentation

> Complete documentation for the UNETLoader node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The UNETLoader node is designed for loading U-Net models by name, facilitating the use of pre-trained U-Net architectures within the system.

This node will detect models located in the `ComfyUI/models/diffusion_models` folder.

## Inputs

| Parameter      | Data Type      | Description                                                                                                                                                                                |
| -------------- | -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `unet_name`    | COMBO\[STRING] | Specifies the name of the U-Net model to be loaded. This name is used to locate the model within a predefined directory structure, enabling the dynamic loading of different U-Net models. |
| `weight_dtype` | ...            | 🚧  fp8\_e4m3fn fp9\_e5m2                                                                                                                                                                  |
