# 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 |
| - | - | - | - | - |
| `prompt` | Text description of the desired image. 1–6000 characters. (default: "") | STRING | Yes | 1 to 6000 characters |
| `model` | Model to use for generation. Selecting a model reveals additional settings for that model. (default: first option, `"uni-1"`) | DYNAMIC\_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 |

### 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. | IMAGE |
