prompt string required

Positive prompt describing the expected elements and visual characteristics in the generated image.

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

Example: 一只坐着的橘黄色的猫, 表情愉悦, 活泼可爱, 逼真准确.

images string[] required

Array of image URLs or Base64-encoded strings. Supports single-image editing and multi-image fusion.

Maximum array length: 3 images. For multi-image input, image order follows the array order.

Image formats: JPEG, JPG, PNG, BMP, WEBP. PNG images do not support transparent channels.

Image width and height: 384 - 5000 pixels.

File size: no more than 10MB.

negative_prompt string

Negative prompt describing content that should not appear in the image. It can be used to constrain 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 768*768 and 1280*1280, and the aspect ratio must be between 1:4 and 4:1. If size is not specified, the system generates an image with total pixels of 1280*1280 by default and approximately preserves aspect ratio as follows: for single-image input, it follows the input image aspect ratio; for multi-image input, it follows the last input image aspect ratio.

Default: 1280*1280

n int

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

Range: 1 - 4

Default: 4

prompt_extend bool

Whether to enable intelligent prompt rewriting. When enabled, a large model rewrites the input prompt to improve overall results, but request latency increases.

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

seed int

Random seed. If omitted, the algorithm automatically generates a random seed. When n=4, the algorithm uses seed, seed+1, seed+2, and seed+3 respectively.

Range: 0 - 2147483647
