# InstructPixToPixConditioning - ComfyUI Built-in Node Documentation

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

The InstructPixToPixConditioning node prepares conditioning data for InstructPix2Pix image editing by combining positive and negative text prompts with image data. It processes input images through a VAE encoder to create latent representations and attaches these latents to both positive and negative conditioning data. The node automatically handles image dimensions by cropping to multiples of 8 pixels for compatibility with the VAE encoding process.

## Inputs

| Parameter  | Description                                                                                         | Data Type    | Required | Range |
| ---------- | --------------------------------------------------------------------------------------------------- | ------------ | -------- | ----- |
| `positive` | Positive conditioning data containing text prompts and settings for desired image characteristics   | CONDITIONING | Yes      | -     |
| `negative` | Negative conditioning data containing text prompts and settings for undesired image characteristics | CONDITIONING | Yes      | -     |
| `vae`      | VAE model used for encoding input images into latent representations                                | VAE          | Yes      | -     |
| `pixels`   | Input image to be processed and encoded into latent space                                           | IMAGE        | Yes      | -     |

**Note:** The input image dimensions are automatically adjusted by cropping to the nearest multiple of 8 pixels in both width and height to ensure compatibility with the VAE encoding process.

## Outputs

| Output Name | Description                                                          | Data Type    |
| ----------- | -------------------------------------------------------------------- | ------------ |
| `positive`  | Positive conditioning data with attached latent image representation | CONDITIONING |
| `negative`  | Negative conditioning data with attached latent image representation | CONDITIONING |
| `latent`    | Empty latent tensor with the same dimensions as the encoded image    | LATENT       |
