# StableCascade_EmptyLatentImage - ComfyUI Built-in Node Documentation

> Complete documentation for the StableCascade_EmptyLatentImage 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/StableCascade_EmptyLatentImage/en.md)

The StableCascade\_EmptyLatentImage node creates empty latent tensors for Stable Cascade models. It generates two separate latent representations - one for stage C and another for stage B - with appropriate dimensions based on the input resolution and compression settings. This node provides the starting point for the Stable Cascade generation pipeline.

## Inputs

| Parameter     | Data Type | Required | Range                  | Description                                                                                     |
| ------------- | --------- | -------- | ---------------------- | ----------------------------------------------------------------------------------------------- |
| `width`       | INT       | Yes      | 256 to MAX\_RESOLUTION | The width of the output image in pixels (default: 1024, step: 8)                                |
| `height`      | INT       | Yes      | 256 to MAX\_RESOLUTION | The height of the output image in pixels (default: 1024, step: 8)                               |
| `compression` | INT       | Yes      | 4 to 128               | The compression factor that determines the latent dimensions for stage C (default: 42, step: 1) |
| `batch_size`  | INT       | No       | 1 to 4096              | The number of latent samples to generate in a batch (default: 1)                                |

## Outputs

| Output Name | Data Type | Description                                                                                           |
| ----------- | --------- | ----------------------------------------------------------------------------------------------------- |
| `stage_c`   | LATENT    | The stage C latent tensor with dimensions \[batch\_size, 16, height//compression, width//compression] |
| `stage_b`   | LATENT    | The stage B latent tensor with dimensions \[batch\_size, 4, height//4, width//4]                      |
