## Overview

This node generates images from text descriptions using the Luma UNI-1 model. It takes a text prompt and optional settings like aspect ratio and style, then sends the request to the Luma API to create an image.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| --- | --- | --- | --- | --- |
| `prompt` | Text description of the desired image. | STRING | Yes | 1–6000 characters |
| `model` | Model to use for generation. Selecting a model reveals additional settings for that model. | COMBO | Yes | `"uni-1"`<br>`"uni-1-max"` |
| `seed` | Seed controls whether the node should re-run; results are non-deterministic regardless of seed. (default: 0) | INT | Yes | 0 to 2147483647 |

### Model-specific Inputs

When `"uni-1"` or `"uni-1-max"` is selected for the `model` parameter, the following inputs become available:

| Parameter | Description | Data Type | Required | Range |
| --- | --- | --- | --- | --- |
| `aspect_ratio` | Output image aspect ratio. `"auto"` lets the model pick based on the prompt. (default: `"auto"`) | COMBO | Yes | `"auto"`<br>`"3:1"`<br>`"2:1"`<br>`"16:9"`<br>`"3:2"`<br>`"1:1"`<br>`"2:3"`<br>`"9:16"`<br>`"1:2"`<br>`"1:3"` |
| `style` | The visual style for the generated image. (default: `"auto"`) | COMBO | Yes | `"auto"`<br>`"manga"` |
| `web_search` | Whether to allow the model to search the web for additional context. (default: False) | BOOLEAN | Yes | True / False |
| `image_ref` | Reference images to guide the generation. | IMAGE | No | Up to 9 images |

**Note on `style` and `aspect_ratio` constraints:** If `style` is set to `"manga"`, the `aspect_ratio` must be either `"auto"` or one of the following portrait ratios: `"2:3"`, `"9:16"`, `"1:2"`, `"1:3"`. Using a landscape or square ratio with `"manga"` style will cause an error.

## Outputs

| Output Name | Description | Data Type |
| --- | --- | --- |
| `image` | The generated image as a tensor. | IMAGE |
