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

API README

Qwen Image 2

Qwen Image 2 is the Image 2 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. This dedicated text-to-image path makes prompt-only generation explicit for applications that never supply an edit source.

Use Qwen Image 2 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

Image 2 Complex scene composition. Coordinates subjects, environment, layout, and style from a detailed brief.
Image 2 Bilingual visual text. Creates Chinese and English words inside posters, signs, and labels.
Image 2 Semantic relationship rendering. Represents how objects and concepts relate rather than only depicting isolated nouns.
Image 2 dedicated text creation. Concentrates the standard Image 2 model on prompt-only scene and designed-image synthesis.

When to Use

✅ Good fit	❌ Consider alternatives
The project needs a new image must be created from a written brief	The intended task belongs to a different media workflow
The available inputs match every required local field	Required source material or usage permission is unavailable
Creative direction can identify subject, style, and delivery	The output must be deterministic at pixel or waveform level
The supported route controls fit the final placement	Delivery requires unsupported formats or dimensions
An asynchronous generated result fits production	A live or frame-synchronous response is mandatory

Prompt Guide

Write the request as a production brief. Identify the subject or source, state the intended result, describe composition and visual or vocal character, then list exact preservation and delivery constraints. For edits, explicitly separate what must change from what must remain unchanged.

{
  "prompt": "A polished editorial composition with a clear subject, controlled lighting, balanced layout, and precisely preserved details",
  "seed": 1,
  "aspect_ratio": "21:9",
  "output_format": "jpeg"
}
