The SaveLoRA node saves a LoRA (Low-Rank Adaptation) model to a file. It takes a LoRA model as input and writes it to a .safetensors file in the output directory. You can specify a filename prefix and an optional step count to be included in the final filename.

Inputs

Parameter	Data Type	Required	Range	Description
lora	MODEL	Yes	N/A	The LoRA model to save. Do not use the model with LoRA layers.
prefix	STRING	Yes	N/A	The prefix to use for the saved LoRA file (default: “loras/ComfyUI_trained_lora”).
steps	INT	No	N/A	Optional: The number of steps the LoRA has been trained for, used to name the saved file.

Note: The lora input must be a pure LoRA model. Do not provide a base model that has LoRA layers applied to it.

Outputs

Output Name	Data Type	Description
None	N/A	This node does not output any data to the workflow. It is an output node that saves a file to disk.
