SaveLoRA - ComfyUI Built-in Node Documentation

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

Note: The lora input must be a pure LoRA model. Do not provide a base model that has LoRA layers applied to it. Note: The file is saved in the ComfyUI output directory with a .safetensors extension. The filename is built from the prefix and a zero-padded counter (5 digits) to avoid overwriting existing files. When steps is provided, the step count is also included in the filename (for example, 1000_steps for 1000 steps).

Outputs

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