Properties
| Name | Type | Description |
|---|---|---|
| prompt | string | Text describing what you wish to see in the output image. |
| negative_prompt | string | Text describing elements to exclude from the output image. |
| image | string | An optional input image for image-to-image generation. When provided, the model uses this image as a reference guided by the strength parameter. |
| strength | number | Controls how much influence the input image has on the output. Lower values produce images closer to the input, higher values allow more creative deviation. Only applicable for image-to-image mode. |
| aspect_ratio | string | Controls the aspect ratio of the generated image. Only applicable for text-to-image mode. |
| model | string | The Stable Diffusion 3 model variant to use for generation. |
| seed | integer | A value to control randomness in generation. |
| output_format | string | The output format of the generated image. |
| mode | string | The generation mode. Use text-to-image for prompt-only generation or image-to-image when providing a reference image. |
