# FluxKVCache - ComfyUI Built-in Node Documentation

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

> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/FluxKVCache/en.md)

The Flux KV Cache node enables a Key-Value (KV) Cache optimization for Flux family models. This optimization improves performance when using reference images by caching certain computations, which can speed up the generation process.

## Inputs

| Parameter | Data Type | Required | Range | Description                                  |
| --------- | --------- | -------- | ----- | -------------------------------------------- |
| `model`   | MODEL     | Yes      |       | The model to apply KV Cache optimization on. |

## Outputs

| Output Name | Data Type | Description                                           |
| ----------- | --------- | ----------------------------------------------------- |
| `model`     | MODEL     | The patched model with KV Cache optimization enabled. |
