# ByteDanceImageNode - ComfyUI Built-in Node Documentation

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

The ByteDance Image node generates images using ByteDance models through an API based on text prompts. It allows you to select a model, specify image dimensions, and control various generation parameters like seed and guidance scale. The node connects to ByteDance's image generation service and returns the created image.

## Inputs

| Parameter        | Data Type | Required | Range                       | Description                                                                                                                                |
| ---------------- | --------- | -------- | --------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------ |
| `model`          | STRING    | Yes      | `"seedream-3-0-t2i-250415"` | The ByteDance model to use for image generation. Currently only one model option is available.                                             |
| `prompt`         | STRING    | Yes      | -                           | The text prompt used to generate the image. Must be at least 1 character long after stripping whitespace.                                  |
| `size_preset`    | STRING    | Yes      | See description             | Pick a recommended size. Select Custom to use the width and height below. Available presets are defined by the `RECOMMENDED_PRESETS` list. |
| `width`          | INT       | Yes      | 512 to 2048 (step 64)       | Custom width for the image. This value is only used when `size_preset` is set to `Custom`. Default: 1024.                                  |
| `height`         | INT       | Yes      | 512 to 2048 (step 64)       | Custom height for the image. This value is only used when `size_preset` is set to `Custom`. Default: 1024.                                 |
| `seed`           | INT       | No       | 0 to 2147483647 (step 1)    | Seed to use for generation. Default: 0.                                                                                                    |
| `guidance_scale` | FLOAT     | No       | 1.0 to 10.0 (step 0.01)     | Higher value makes the image follow the prompt more closely. Default: 2.5.                                                                 |
| `watermark`      | BOOLEAN   | No       | True / False                | Whether to add an "AI generated" watermark to the image. Default: False. This is an advanced parameter.                                    |

**Note on size parameters:** The `width` and `height` parameters are only used when `size_preset` is set to `Custom`. If a preset size is selected, the preset's dimensions override the custom width and height values. Both width and height must be between 512 and 2048 pixels when using custom dimensions.

## Outputs

| Output Name | Data Type | Description                                                      |
| ----------- | --------- | ---------------------------------------------------------------- |
| `IMAGE`     | IMAGE     | The generated image returned from the ByteDance API as a tensor. |
