prompt string required

Positive prompt describing the expected image content, style, and composition.

Chinese and English are supported. Maximum length: 2000 characters. Extra content is automatically truncated.

negative_prompt string

Negative prompt describing content that should not appear in the image.

Chinese and English are supported. Maximum length: 500 characters. Extra content is automatically truncated.

size string

Output image resolution in width*height format.

Total pixels must be between 1280*1280 and 1440*1440, and the aspect ratio must be between 1:4 and 4:1.

Common recommended resolutions: 1280*1280, 1104*1472, 1472*1104, 960*1696, 1696*960

Default: 1280*1280

n int

Number of images to generate. This parameter directly affects cost; set it to 1 during testing.

Range: 1 - 4

Default: 4

seed int

Random seed. Using the same seed can make generated content relatively stable. If omitted, the algorithm automatically uses a random seed.

Range: 0 - 2147483647

prompt_extend bool

Whether to enable intelligent prompt rewriting. When enabled, a large model optimizes the positive prompt, which can noticeably improve short prompts but increases latency.

Options: true, false

Default: true

watermark bool

Whether to add a watermark in the lower-right corner of the image. The fixed watermark text is AI生成.

Options: false, true

Default: false
