Input Schema

4 parameters · 1 required · 3 optional

Parameter	Type	Required	Description
`prompt`	string	Required	The prompt to generate an image from.
`seed`	integer	Optional	The same seed and the same prompt given to the same version of the model will output the same image every time.
`aspect_ratio`	string	Optional	The aspect ratio of the generated image. · Options: 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16 21:916:93:24:35:41:14:53:42:39:16
`output_format`	string	Optional	The format of the generated image. · Options: jpeg, png · Default: "png" jpegpng

Output Schema

Field	Type	Description
`id`	string	Unique identifier for the generation task
`status`	string	Task status: pending, running, completed, failed, timeout
`model`	string	Model used for the generation
`outputs`	array	Array of output items
`outputs[].url`	string	URL of the generated artifact
`outputs[].content_type`	string	MIME type (e.g. image/png, video/mp4)
`error`	object \| null	Error details if failed, null on success
`error.type`	string	Machine-readable error type code
`error.message`	string	Human-readable error description

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response

Code Examples

API README

Qwen Image 2512

Qwen Image 2512 is the 2512 route for prompt-led image creation. It uses Qwen’s combined visual-semantic and appearance modeling to interpret subjects, relationships, typography, spatial structure, and surface detail as a connected composition, giving this exact route a clearer production purpose than a generic image request.

Use Qwen Image 2512 when the project specifically requires a new visual built from a detailed brief. State the creative goal, then define composition, viewpoint, wording, materials, lighting, and finish; for edits, explicitly separate the intended transformation from identity, layout, or regions that must remain stable.

Highlights

2512 Complex scene composition. Coordinates subjects, environment, layout, and style from a detailed brief.
2512 Bilingual visual text. Creates Chinese and English words inside posters, signs, and labels.
2512 Semantic relationship rendering. Represents how objects and concepts relate rather than only depicting isolated nouns.
2512 Photographic and graphic versatility. Supports realistic scenes, illustration, product imagery, and designed assets.

Base generation	Per request	$0.02

When to Use

✅ Good fit	❌ Consider alternatives
The project needs this exact named workflow	The intended task belongs to another media route
All required reference or control media is available	Necessary assets or rights are unavailable
The brief can state transformation and preservation goals	Output must be deterministic at pixel or frame level
Supported duration, resolution, and format fit delivery	Final placement requires unsupported specifications
An asynchronous generated result fits production	A live frame-synchronous response is mandatory

Prompt Guide

Identify the primary subject and every source or condition, state the intended transformation or action, then describe composition, camera or viewpoint, lighting, materials, pacing, atmosphere, and exact preservation requirements. Refer to multiple inputs in their schema order.

{
  "prompt": "A precisely directed composition with explicit subject, transformation, camera or viewpoint, lighting, material, and preservation requirements",
  "seed": 1,
  "aspect_ratio": "21:9",
  "output_format": "jpeg"
}
