| prompt* | string | The prompt to use for generating the image. Be as descriptive as possible for best results. | |
| num_inference_steps | integer | The number of inference steps to perform. | 1 ≤ n ≤ 70 · default: 35 |
| loras | LoraWeight[] | The list of LoRA weights to use. | default: [] |
| seed | integer | The same seed and the same prompt given to the same version of Stable Diffusion will output the same image every time. | nullable |
| num_images | integer | The number of images to generate. | 1 ≤ n ≤ 8 · default: 1 |
