# Kling 3.0 Image Generation Node

Kling Image Generation Node generates images from text prompts with the option to use a reference image for guidance. It creates one or more images based on your text description and reference settings, then returns the generated images as output.

## Inputs

| Parameter | Description | Data Type | Required | Range |
|-----------|-------------|-----------|----------|-------|
| `prompt` | Positive text prompt | STRING | Yes | Maximum 500 characters |
| `negative_prompt` | Negative text prompt | STRING | Yes | Maximum 500 characters |
| `image_type` | Image reference type selection (advanced). Required when a reference image is provided. | COMBO | Yes | `"subject_reference"`<br>`"style_reference"` |
| `image_fidelity` | Reference intensity for user-uploaded images (default: 0.5, advanced) | FLOAT | Yes | 0.0 - 1.0 |
| `human_fidelity` | Subject reference similarity (default: 0.45, advanced) | FLOAT | Yes | 0.0 - 1.0 |
| `model_name` | Model selection for image generation (default: "kling-v3") | COMBO | Yes | `"kling-v3"`<br>`"kling-v2"`<br>`"kling-v1-5"` |
| `aspect_ratio` | Aspect ratio for generated images (default: "16:9") | COMBO | Yes | `"16:9"`<br>`"9:16"`<br>`"1:1"`<br>`"4:3"`<br>`"3:4"`<br>`"21:9"`<br>`"9:21"` |
| `n` | Number of generated images (default: 1) | INT | Yes | 1 - 9 |
| `image` | Optional reference image | IMAGE | No | - |
| `seed` | Seed controls whether the node should re-run; results are non-deterministic regardless of seed (default: 0) | INT | No | 0 - 2147483647 |

**Parameter Constraints:**

- The `image` parameter is optional. When a reference image is provided, the `image_type` parameter must be set to either `"subject_reference"` or `"style_reference"`.
- When no reference image is provided, the `image_type`, `image_fidelity`, and `human_fidelity` parameters are not used.
- Prompt and negative prompt have a maximum length of 500 characters.
- The `seed` parameter is optional and does not guarantee deterministic results.

## Outputs

| Output Name | Description | Data Type |
|-------------|-------------|-----------|
| `output` | Generated image(s) based on the input parameters | IMAGE |
