Input parameters

Name	Type	Required	Description
`prompt`	string	required	The positive prompt that describes the image content, style, and composition you want to generate or edit. Both Chinese and English are supported.
`resolution`	string	optional	The output image resolution. Values: `1K`, `2K`
`image_size`	string	optional	The output image size. Values: `1:1`, `3:2`, `2:3`, `4:3`, `3:4`, `16:9`, `9:16`, `21:9` Default: `16:9`
`output_format`	string	optional	The generated image format. Values: `png`, `jpeg` Default: `png`
`prompt_extend`	boolean	optional	Whether to enable intelligent prompt rewriting. Default: true (recommended). When enabled, the model optimizes the positive prompt, which significantly improves results for simple descriptions. Default: `True`
`nsfw_checker`	boolean	optional	Whether to enable content filtering. Optional. Defaults to false. When set to false, content filtering is disabled and all results are returned directly by the model. Note: Content filtering cannot guarantee that all inappropriate content will be detected. If the filtering results do not meet your requirements, you must implement additional content moderation measures. Default: `False`
`negative_prompt`	string	optional	The negative prompt that describes content you do not want to appear in the image.
`seed`	integer	optional	The random seed. Value range: [0, 2147483647]. A fixed seed helps maintain relatively stable results. Default: `1`
