# LumaImageNode2 - ComfyUI Built-in Node Documentation

> This node generates images from text descriptions using the Luma UNI-1 model.

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. Two model variants are available: `uni-1` and `uni-1-max`.

## Inputs

### Common Inputs

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

### uni-1 and uni-1-max Inputs

Shared by the `uni-1` and `uni-1-max` model options. These settings appear when either model is selected.

| 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`        | Style preset. `"auto"` picks based on the prompt; `"manga"` applies a manga/anime aesthetic and requires a portrait aspect ratio (2:3, 9:16, 1:2, 1:3). (default: `"auto"`) | COMBO     | Yes      | `"auto"`<br />`"manga"`                                                                                                         |
| `web_search`   | Search the web for visual references before generating. (default: False)                                                                                                    | BOOLEAN   | Yes      | True / False                                                                                                                    |

### Reference Inputs

| Parameter   | Description                                                                                                             | Data Type | Required | Range          |
| ----------- | ----------------------------------------------------------------------------------------------------------------------- | --------- | -------- | -------------- |
| `image_ref` | Growable slot: connect 1 to 9 items (e.g. `image_1` to `image_9`). Up to 9 reference images for style/content guidance. | IMAGE     | No       | Up to 9 images |

**Note:** If `style` is set to `"manga"`, the `aspect_ratio` must be either `"auto"` or one of the portrait ratios `"2:3"`, `"9:16"`, `"1:2"`, `"1:3"`. Using any other ratio with `"manga"` style will cause an error. The maximum number of reference images is 9 for both `uni-1` and `uni-1-max`.

## Outputs

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