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.

Inputs

Parameter	Data Type	Required	Range	Description
`model`	MODEL	Yes	-	The diffusion model the LoRA will be applied to.
`lora`	LORA_MODEL	Yes	-	The LoRA model to apply to the diffusion model.
`strength_model`	FLOAT	Yes	-100.0 to 100.0	How strongly to modify the diffusion model. This value can be negative (default: 1.0).

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

Outputs

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