This node creates a hook model as a LoRA (Low-Rank Adaptation) by loading checkpoint weights and applying strength adjustments to both the model and CLIP components. It allows you to apply LoRA-style modifications to existing models through a hook-based approach, enabling fine-tuning and adaptation without permanent model changes. The node can combine with previous hooks and caches loaded weights for efficiency.

Inputs

Parameter	Data Type	Required	Range	Description
ckpt_name	STRING	Yes	Multiple options available	The checkpoint file to load weights from (select from available checkpoints)
strength_model	FLOAT	Yes	-20.0 to 20.0	The strength multiplier applied to the model weights (default: 1.0)
strength_clip	FLOAT	Yes	-20.0 to 20.0	The strength multiplier applied to the CLIP weights (default: 1.0)
prev_hooks	HOOKS	No	-	Optional previous hooks to combine with the newly created LoRA hooks

Parameter Constraints:

• The ckpt_name parameter loads checkpoints from the available checkpoints folder
• Both strength parameters accept values from -20.0 to 20.0 with 0.01 step increments
• When prev_hooks is not provided, the node creates a new hook group
• The node caches loaded weights to avoid reloading the same checkpoint multiple times

Outputs

Output Name	Data Type	Description
HOOKS	HOOKS	The created LoRA hooks, combined with any previous hooks if provided
