# MiniMax H3 Image - ComfyUI Built-in Node Documentation

> Generates images from text with MiniMax H3 Image, or edits and combines up to 16 reference images.

Generates images from text with MiniMax H3 Image, or edits and combines up to 16 reference images. The prompt refers to the references by connection order: `@Image1`, `@Image2`, and so on.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `model` | `MiniMax-H3-Image`, or `MiniMax-H3-Image-Highspeed` for faster runs. Default: `"MiniMax-H3-Image"`. | COMBO | Yes | `"MiniMax-H3-Image"` `"MiniMax-H3-Image-Highspeed"` |
| `prompt` | What to generate, or how to edit the references. With reference images connected it can be at most 8,000 characters. Default: empty. | STRING | Yes | 1 to 8000 characters |
| `size` | `2K` and `4K` derive the size from an aspect ratio; `custom` sets an exact width and height. Default: `"2K"`. | DYNAMIC\_COMBO | Yes | `"2K"` `"4K"` `"custom"` |
| `enhance_prompt` | MiniMax rewrites the prompt into a detailed scene description before generating. Image edits are always enhanced. When off, pick a fixed aspect ratio or a custom size. Default: true. | BOOLEAN | No | true false |
| `seed` | Controls whether the node re-runs; results are non-deterministic regardless of the seed. Default: 42. | INT | No | 0 to 2147483647 |
| `images` | Reference images to edit or combine, addressed in the prompt as `@Image1` to `@Image16` in connection order. | AUTOGROW | No | Up to 16 images |

### Size "2K" and "4K" Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `aspect_ratio` | With `auto`, MiniMax picks the ratio from the prompt, or follows the reference image when one is connected. Text to image with `enhance_prompt` off needs a fixed ratio. Default: `"auto"`. | COMBO | Yes | Multiple options available |

### Size "custom" Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `width` | Output width in pixels. Default: 2048. | INT | Yes | 512 to 7680 (step 16) |
| `height` | Output height in pixels. Default: 2048. | INT | Yes | 512 to 7680 (step 16) |

Note: For a custom size, width times height must be between 655,360 and 20,000,000 pixels with an aspect ratio of at most 3:1.

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `image` | The generated or edited image, as PNG. | IMAGE |
| `revised_prompt` | The rewritten prompt MiniMax used, when prompt enhancement was on. | STRING |
