Model parameters

What the model itself understands; the ordering calls above take their own fields and pass these on.

NameTypeRequiredDescription
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.
