negative_prompt	string	Text describing elements to exclude from the output image.
aspect_ratio	string	Controls the aspect ratio of the generated image.
seed	integer	A value to control randomness in generation. Set to 0 for a random seed. Using the same seed with the same parameters produces similar results.
output_format	string	The output format of the generated image.
