LoraLoaderBypass - ComfyUI Built-in Node Documentation

The LoraLoaderBypass node applies a LoRA (Low-Rank Adaptation) to a diffusion model and a CLIP model in a special “bypass” mode. Unlike a standard LoRA loader, this method does not permanently modify the base model’s weights. Instead, it computes the output by adding the LoRA’s effect to the model’s normal forward pass, which is useful for training or when working with models that have their weights offloaded.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The diffusion model the LoRA will be applied to.	MODEL	Yes	-
`clip`	The CLIP model the LoRA will be applied to.	CLIP	Yes	-
`lora_name`	The name of the LoRA file to apply. The options are loaded from the `loras` folder.	COMBO	Yes	List of available LoRA files
`strength_model`	How strongly to modify the diffusion model. This value can be negative (default: 1.0).	FLOAT	Yes	-100.0 to 100.0
`strength_clip`	How strongly to modify the CLIP model. This value can be negative (default: 1.0).	FLOAT	Yes	-100.0 to 100.0

Note: If both strength_model and strength_clip are set to 0, the node will return the original, unmodified model and clip inputs without processing.

Outputs

Output Name	Description	Data Type
`MODEL`	The diffusion model with the LoRA applied in bypass mode.	MODEL
`CLIP`	The CLIP model with the LoRA applied in bypass mode.	CLIP
