SaveConditioning - ComfyUI Built-in Node Documentation - ComfyUI

This node saves a single conditioning to the output folder as a safetensors file. The saved file can be moved to the models/embeddings folder and loaded later with Load Conditioning, for example to skip the text encoder. The node passes the conditioning through unchanged so it can still be used later in the workflow.

Inputs

Parameter	Description	Data Type	Required	Range
`conditioning`	The conditioning to save. Only a single conditioning entry is supported.	CONDITIONING	Yes	-
`filename_prefix`	Prefix used to build the output filename. The file is written to the output folder with a numeric counter appended. Default: `conditioning/ComfyUI`	STRING	Yes	-

Notes:

If the conditioning input contains more than one entry (for example after combining conditionings), the node raises an error: “Save Conditioning supports a single conditioning entry, save it before combining.”
Conditioning options that are tensors, lists/tuples of tensors, booleans, integers, floats, or strings are saved alongside the conditioning. Options that are None are skipped. Any other option type raises an error stating the option cannot be saved.

Outputs

Output Name	Description	Data Type
`conditioning`	The same conditioning that was passed in, unchanged.	CONDITIONING
