# ByteDanceSeedNode - ComfyUI Built-in Node Documentation

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

## Overview

Generate text responses using ByteDance's Seed 2.0 models. Provide a text prompt and optionally include images or videos for multimodal context.

## Inputs

| Parameter       | Description                                                                                                  | Data Type | Required | Range                                                          |
| --------------- | ------------------------------------------------------------------------------------------------------------ | --------- | -------- | -------------------------------------------------------------- |
| `prompt`        | Text input to the model.                                                                                     | STRING    | Yes      | N/A                                                            |
| `model`         | The Seed model used to generate the response.                                                                | COMBO     | Yes      | `"Seed 2.0 Pro"`<br />`"Seed 2.0 Lite"`<br />`"Seed 2.0 Mini"` |
| `seed`          | Seed controls whether the node should re-run; results are non-deterministic regardless of seed. (default: 0) | INT       | Yes      | 0 to 2147483647                                                |
| `system_prompt` | Foundational instructions that dictate the model's behavior. (default: "")                                   | STRING    | No       | N/A                                                            |

**Note on `model` parameter:** The `model` parameter is a dynamic combo that also accepts images and videos. You can connect image and video inputs to this parameter to provide multimodal context. A maximum of 20 images and 4 videos are supported per request.

## Outputs

| Output Name | Description                                      | Data Type |
| ----------- | ------------------------------------------------ | --------- |
| `output`    | The generated text response from the Seed model. | STRING    |
