CreateHookLora - ComfyUI Built-in Node Documentation

The Create Hook LoRA node generates hook objects for applying LoRA (Low-Rank Adaptation) modifications to models. It loads a specified LoRA file and creates hooks that can adjust model and CLIP strengths, then combines these hooks with any existing hooks passed to it. The node efficiently manages LoRA loading by caching previously loaded LoRA files to avoid redundant operations.

Inputs

Parameter	Description	Data Type	Required	Range
`lora_name`	The name of the LoRA file to load from the loras directory	STRING	Yes	Multiple options available
`strength_model`	The strength multiplier for model adjustments (default: 1.0)	FLOAT	Yes	-20.0 to 20.0
`strength_clip`	The strength multiplier for CLIP adjustments (default: 1.0)	FLOAT	Yes	-20.0 to 20.0
`prev_hooks`	Optional existing hook group to combine with the new LoRA hooks	HOOKS	No	N/A

Parameter Constraints:

If both strength_model and strength_clip are set to 0, the node will skip creating new LoRA hooks and return the existing hooks unchanged
The node caches the last loaded LoRA file to optimize performance when the same LoRA is used repeatedly

Outputs

Output Name	Description	Data Type
`HOOKS`	A hook group containing the combined LoRA hooks and any previous hooks	HOOKS
