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 |

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 2.5 Text to Image
Wan 2.5 Text to Image is the Wan 2.5 workflow for text-to-image creation. It models visual appearance and time together so the route’s written direction, source imagery, speech, masks, or structural conditions influence one coherent result rather than a collection of disconnected frames or a generic endpoint response.
Choose this exact route when the available assets and deliverable specifically call for text-to-image creation. Identify every subject and source, state the desired action or transformation, then describe camera behavior, pacing, environment, lighting, atmosphere, and preservation requirements; local schema fields handle resolution, duration, seed, and delivery separately from the creative brief.
Highlights
- 2.5 Prompt-faithful composition. Builds subject, environment, layout, lighting, and style from written direction.
- 2.5 Detailed visual rendering. Produces coherent materials, texture, illumination, and spatial relationships.
- 2.5 Chinese and English visual text. Supports visible wording in both languages within generated imagery.
- 2.5 Creative-domain range. Covers photographic, illustrative, product, and graphic-design directions.

When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The project needs this exact text-to-image workflow | The intended task belongs to a different media route |
| Available source media matches every required field | Required assets or usage rights are unavailable |
| The brief can define subject, action, camera, and style | Output must be deterministic at frame or pixel level |
| Supported duration, resolution, and framing fit delivery | Final placement requires unsupported specifications |
| An asynchronous generation job fits production | A live or frame-synchronous response is mandatory |
Prompt Guide
Describe the result as a shot or design brief: identify subjects and references, state the action or transformation, specify environment and composition, then add camera behavior, lighting, pacing, style, sound, and preservation constraints where relevant. Use exact reference identifiers exposed by the local schema.

"prompt": "A cinematic scene with clearly directed subject action, camera movement, lighting, pacing, and atmosphere",
