Generates images synchronously based on prompt and aspect ratio. This node creates images using text descriptions and allows you to control the image dimensions and style through various reference inputs.

## Inputs

| Parameter            | Data Type | Required | Range                      | Description                                                                                                  |
| -------------------- | --------- | -------- | -------------------------- | ------------------------------------------------------------------------------------------------------------ |
| `prompt`             | STRING    | Yes      | -                          | Prompt for the image generation (default: empty string)                                                      |
| `model`              | COMBO     | Yes      | Multiple options available | Model selection for image generation                                                                         |
| `aspect_ratio`       | COMBO     | Yes      | Multiple options available | Aspect ratio for the generated image (default: 16:9 ratio)                                                   |
| `seed`               | INT       | Yes      | 0 to 18446744073709551615  | Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0) |
| `style_image_weight` | FLOAT     | No       | 0.0 to 1.0                 | Weight of style image. Ignored if no style\_image provided (default: 1.0)                                    |
| `image_luma_ref`     | LUMA\_REF | No       | -                          | Luma Reference node connection to influence generation with input images; up to 4 images can be considered   |
| `style_image`        | IMAGE     | No       | -                          | Style reference image; only 1 image will be used                                                             |
| `character_image`    | IMAGE     | No       | -                          | Character reference images; can be a batch of multiple, up to 4 images can be considered                     |

**Parameter Constraints:**

* The `image_luma_ref` parameter can accept up to 4 reference images
* The `character_image` parameter can accept up to 4 character reference images
* The `style_image` parameter accepts only 1 style reference image
* The `style_image_weight` parameter is only used when `style_image` is provided

| ----------- | --------- | ------------------------------------------------- |
| `output`    | IMAGE     | The generated image based on the input parameters |
