Input parameters

Name	Type	Required	Description
`prompt`	string	required	The text prompt used to generate the image (Max length: 5000 characters)
`image_size`	string	optional	The size of the generated image. Values: `square`, `square_hd`, `portrait_4_3`, `portrait_3_2`, `portrait_16_9`, `landscape_4_3`, `landscape_3_2`, `landscape_16_9`, `landscape_21_9` Default: `square_hd`
`image_resolution`	string	optional	Final image resolution is determined by combining image_size (aspect ratio) and image_resolution (pixel scale). For example, choosing 4:3 + 4K gives 4096 × 3072px Values: `1K`, `2K`, `4K` Default: `1K`
`max_images`	number	optional	Set this value (1–6) to cap how many images a single generation run can produce in one set—because they’re created in one shot rather than separate requests, you must also state the exact number you want in the prompt so both settings align. (Min: 1, Max: 6, Step: 1) (step: 1) Default: `1`
`seed`	integer	optional	Random seed to control the stochasticity of image generation
`nsfw_checker`	boolean	optional	Defaults to false. You can set it to false based on your needs. If set to false, our content filtering will be disabled, and all results will be returned directly by the model itself. Note: There is no guarantee that everything can be filtered out; if you are not satisfied with the results, you will need to make your own arrangements.
