# LoraModelLoader - ComfyUI Built-in Node Documentation

> The LoraModelLoader node applies trained LoRA (Low-Rank Adaptation) weights to a diffusion model.

The LoraModelLoader node applies trained LoRA (Low-Rank Adaptation) weights to a diffusion model. It modifies the base model by loading LoRA weights from a trained LoRA model and adjusting their influence strength. This allows you to customize the behavior of diffusion models without retraining them from scratch, including a bypass mode that leaves the base model weights unchanged.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `model` | The diffusion model the LoRA will be applied to. | MODEL | Yes | - |
| `lora` | The LoRA model to apply to the diffusion model. | LORA\_MODEL | Yes | - |
| `strength_model` | How strongly to modify the diffusion model. This value can be negative (default: 1.0). | FLOAT | Yes | -100.0 to 100.0 |
| `bypass` | When enabled, applies LoRA in bypass mode without modifying base model weights. Useful for training and when model weights are offloaded (default: False). | BOOLEAN | Yes | True or False |

**Note:** When `strength_model` is set to 0, the node returns the original model without applying any LoRA modifications.

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `model` | The modified diffusion model with LoRA weights applied. | MODEL |
