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, ortimeout - Retrieve — Read
outputsfrom the completed response

Wan 2.7 Pro Text-to-Image
Wan 2.7 Pro is the text-to-image route in the Wan 2.7 Pro family. It turns a written creative brief into a finished image URL, giving image-generation workflows a direct path from concept text to a visual asset.
The endpoint packages generation and delivery into one asynchronous job. This makes it practical to iterate on a visual brief, compare results, and carry the selected output into a broader design workflow.
Highlights
Enhanced Pro quality. The Pro route is positioned for enhanced-quality image generation, producing a more refined result than a draft-oriented text-to-image workflow.
Advanced prompt understanding. Interprets detailed written direction so the generated image can follow a richer creative brief rather than only a short subject label.
Detailed image output. Produces detailed visual results, supporting prompts in which the requested image depends on clearly resolved content rather than a loose thumbnail concept.
Native 4K text-to-image output. The Pro model supports high-resolution 4K output for text-to-image generation.

When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The model's named workflow matches the source material and intended output | A different input modality or model route is required |
| A managed asynchronous result is suitable for the production pipeline | A synchronous, interactive editor is essential |
| The documented controls cover the required duration, framing, or format | The project needs controls outside this endpoint's schema |
| Creative iteration benefits from a repeatable request structure | Exact deterministic pixels, frames, geometry, or samples are mandatory |
| A finished downloadable media asset is the desired deliverable | Editable source layers or a native project file are required |
Prompt Guide
For generation, state the intended result first, then add the subject or source treatment, progression, style, and delivery constraints. Keep one creative variable per phrase, use the documented field names for controls, and change one setting at a time when comparing results.
