Qwen

Qwen-Image 3.0 Pro

Qwen-Image 3.0 Pro text-to-image and image editing in a single endpoint. Pass image_list to edit reference images (1-3), or omit it for pure text-to-image. Always returns a single image.

Pricing — output tier plus a surcharge per reference image:

What	Tokens	USD
Output, 1K	2.43	$0.049
Output, 2K	4.85	$0.097
Each reference image	0.19	$0.0039

Example: 2K with 3 reference images = 4.85 + 3 x 0.19 = 5.42 tokens.

image_size decides the price tier. Two cases are billed differently from what you send: ratio: auto is always billed at the 2K rate (the model picks the resolution, so it cannot be known up front), and 1:8 / 8:1 are always billed at the 1K rate (they cannot be produced above that tier).

For a cheaper flat rate use /api/v1/qwen-image-3, where both tiers cost 1.75 tokens.

Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the generated image.

Headers

Authorization

string

Body

application/json

prompt

string

required

Text prompt describing the image.

Required string length: 1 - 2000

ratio

enum<string>

default:auto

Aspect ratio. Defaults to auto, which lets the model pick the resolution from the prompt. Note: 1:8 and 8:1 are only produced at the 1K tier.

Available options:

auto,

1:1,

16:9,

9:16,

4:3,

3:4,

3:2,

1:2,

2:1,

1:4,

4:1,

1:8,

8:1

image_size

enum<string>

default:2K

Output resolution tier, together with ratio it decides the exact pixel size. See the pricing note above — it also decides what you pay.

Available options:

1K,

2K

image_list

object[]

Optional reference images for image editing, [{"url": "https://..."}]. Up to 3 images, each under 10MB. The array order is the order the prompt refers to them in. Each one adds 0.19 tokens.

Required array length: 1 - 3 elements

negative_prompt

string

Optional. Describes what should not appear in the image.

Maximum string length: 2000

seed

integer

Optional. Fixing the seed makes results more reproducible.

Required range: 0 <= x <= 2147483647

prompt_extend_mode

enum<string>

default:direct

Prompt rewriting mode. agent rewrites more thoroughly but is text-to-image only — sending it together with image_list is rejected.

Available options:

direct,

agent

custom_callback_url

string<uri>

Optional. A publicly accessible HTTPS URL. When the task status changes (processing / success / failed), GoEnhance sends a POST request to this URL. The request body is identical to the response of GET /api/v1/jobs/detail. If your server does not respond with HTTP 200, the notification is retried up to 3 times, with a 3-second timeout per attempt.

Example:

"https://your-server.com/goenhance/callback"
