TypeScript Definitions

Use the request body type in TypeScript.

model*string

Platform model ID.

prompt*string

Image editing prompt; enhancement is always enabled. Counted in Unicode characters excluding surrounding whitespace; cannot be blank.

Length1 <= length <= 32000

n?integer

Number of images to generate.

Range1 <= value <= 10

Default1

size?string

auto or WIDTHxHEIGHT, default auto. Custom area: 655,360–20,000,000 pixels; aspect ratio: 1:3–3:1. Omit aspect_ratio and area when specifying dimensions.

Default"auto"

aspect_ratio?string

Default auto, determined by the enhanced prompt and, for editing, reference images. Alternatively, use X:Y with integers X and Y from 1–300 and a ratio of 1:3–3:1. Only used when size is omitted or auto.

area?string

Area preset, default 4K. Only used when size is omitted or auto; actual dimensions are in data[].size.

Value in

"1K"
"2K"
"4K"

output_format?string

Image format. jpg and jpeg are equivalent; responses use jpeg.

Default"jpeg"

Value in

"jpeg"
"jpg"
"png"
"webp"

response_format?string

url links expire after 24 hours; b64_json returns Base64 without streaming. Total Base64 output area is limited to 20,000,000 pixels for PNG or 80,000,000 pixels for JPEG/WebP, summed across images.

Default"url"

Value in

"url"
"b64_json"

output_compression?integer

JPEG/WebP compression quality; higher values produce larger files. Ignored for PNG.

Range0 <= value <= 100

Default95

stream?boolean

Return each image over SSE; only supports response_format set to url.

Defaultfalse

aigc_watermark?boolean

Add a visible AIGC watermark; does not affect the implicit identifier in file metadata.

Defaultfalse

image*array<>

1–16 reference images. Supports JPG, JPEG, PNG, WEBP, HEIC and HEIF. Each image and the whole request body must each be at most 64 MiB; side lengths 128–8192 pixels; long-to-short-side ratio at most 4:1. Base64 encoding counts toward request size. Use one image field per file, or image[] for multiple files; upload order determines image numbering.

Items1 <= items <= 16

JSON image references

JSON requests submit reference images as an images array of objects; other fields match file upload requests.
