## Overview

This node creates an empty latent image in pixel space, specifically designed for the HiDream-O1-Image model. It generates a blank tensor of zeros that serves as the starting point for image generation, with dimensions defined by the width, height, and batch size inputs.

## Inputs

| Parameter    | Data Type | Required | Range                 | Description                                                                                                                                                                |
| ------------ | --------- | -------- | --------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `width`      | INT       | Yes      | 64 to 4096 (step: 32) | The width of the latent image in pixels (default: 2048). The model was trained at \~4 megapixels; lower resolutions go off-distribution and quality regresses noticeably.  |
| `height`     | INT       | Yes      | 64 to 4096 (step: 32) | The height of the latent image in pixels (default: 2048). The model was trained at \~4 megapixels; lower resolutions go off-distribution and quality regresses noticeably. |
| `batch_size` | INT       | No       | 1 to 64               | The number of latent images to generate in a single batch (default: 1).                                                                                                    |

## Outputs

| Output Name | Data Type | Description                                                                                                 |
| ----------- | --------- | ----------------------------------------------------------------------------------------------------------- |
| `samples`   | LATENT    | A tensor filled with zeros representing the empty latent image, with shape (batch\_size, 3, height, width). |

## Notes

* The HiDream-O1-Image model was trained at approximately 4 megapixels. Using significantly lower resolutions may result in reduced image quality.
* Trained resolutions include: 2048x2048, 2304x1728, 1728x2304, 2560x1440, 1440x2560, 2496x1664, 1664x2496, 3104x1312, 1312x3104, 2304x1792, 1792x2304.
