# USOStyleReference - ComfyUI Built-in Node Documentation

> The USOStyleReference node applies a style reference to a model by combining CLIP vision features with a model patch, and returns a patched copy of the input model.

The USOStyleReference node applies a style reference to a model by combining CLIP vision features with a model patch, and returns a patched copy of the input model. It is intended for Flux models and is marked as experimental. The visual style information is combined with the model's text conditioning so it can influence generation.

## Inputs

| Parameter            | Description                                                                                  | Data Type            | Required | Range |
| -------------------- | -------------------------------------------------------------------------------------------- | -------------------- | -------- | ----- |
| `model`              | The base model to which the style reference patch is applied.                                | MODEL                | Yes      | -     |
| `model_patch`        | The model patch containing the projection model used to encode the reference image features. | MODEL\_PATCH         | Yes      | -     |
| `clip_vision_output` | The encoded visual features extracted from CLIP vision processing of the reference image.    | CLIP\_VISION\_OUTPUT | Yes      | -     |

Note: The `clip_vision_output` must come from a CLIP vision model that provides the full hidden states and the penultimate hidden state. The node combines the 20th-from-last, 11th-from-last, and penultimate hidden states into the style embedding. The `model_patch` must expose a projection model through its `model` attribute that converts these image features into the style embedding. During sampling, the style embedding is prepended to the text conditioning so it can influence generation.

## Outputs

| Output Name | Description                                                | Data Type |
| ----------- | ---------------------------------------------------------- | --------- |
| `model`     | The modified model with the style reference patch applied. | MODEL     |
