Input Parameters

cfg Type: numberDefault: 5Range: 1 - 10: The guidance scale tells the model how similar the output should be to the prompt.
seed Type: integer: Set a seed for reproducibility. Random by default.
image Type: string: Input image for image to image mode. The aspect ratio of your output will match this image.
prompt (required) Type: string: Text prompt for image generation
aspect_ratio Default: 1:1: The aspect ratio of your output image. This value is ignored if you are using an input image.
output_format Default: webp: Format of the output images
negative_prompt Type: string: What you do not want to see in the image
prompt_strength Type: numberDefault: 0.85Range: 0 - 1: Prompt strength (or denoising strength) when using image to image. 1.0 corresponds to full destruction of information in image.
