## Input Parameters

- `aspect_ratio` (string, optional): Image aspect ratio. Use 'match_input_image' to automatically match the input image's aspect ratio. (Default: `match_input_image`; Options: `match_input_image`, `1:1`, `4:3`, `3:4`, `16:9`, `9:16`, `3:2`, `2:3`, `21:9`)

- `image_input` (array, optional): Input image(s) for image-to-image generation. List of 1-14 images for single or multi-reference generation. (Default: `[]`)
- `max_images` (integer, optional): Maximum number of images to generate when sequential_image_generation='auto'. Range: 1-15. Total images (input + generated) cannot exceed 15. (Default: `1`; Range: min: 1, max: 15)
- `sequential_image_generation` (string, optional): Group image generation mode. 'disabled' generates a single image. 'auto' lets the model decide whether to generate multiple related images (e.g., story scenes, character variations). (Default: `disabled`; Options: `disabled`, `auto`)
