# VAESave - ComfyUI Built-in Node Documentation

> Complete documentation for the VAESave node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The VAESave node is designed for saving VAE models along with their metadata, including prompts and additional PNG information, to a specified output directory. It encapsulates the functionality to serialize the model state and associated information into a file, facilitating the preservation and sharing of trained models.

## Inputs

| Parameter         | Data Type | Description                                                                                                                                     |
| ----------------- | --------- | ----------------------------------------------------------------------------------------------------------------------------------------------- |
| `vae`             | VAE       | The VAE model to be saved. This parameter is crucial as it represents the model whose state is to be serialized and stored.                     |
| `filename_prefix` | STRING    | A prefix for the filename under which the model and its metadata will be saved. This allows for organized storage and easy retrieval of models. |

## Outputs

The node doesn't have output types.
