Specifications

Provider-documented facts. “Not collected” means we have not verified that field yet, not that the feature is unsupported.

API aliases
wanx-sketch-to-image-liteSource for API aliases (opens in a new tab)
Published availability regions
China (Beijing)Source for Published availability regions (opens in a new tab)
Synchronous generation
Not supportedSource for Synchronous generation (opens in a new tab)

HTTP is asynchronous. SDK blocking helpers, where provided, wait for an async task; they do not establish a separate synchronous model endpoint.

Request mode
Async HTTP task with X-DashScope-Async: enable; retrieve results via GET /api/v1/tasks/{task_id}.Source for Request mode (opens in a new tab)
Output link expiry
Task IDs and generated-image links remain available for 24 hours. This does not establish input-retention or training-use policy.Source for Output link expiry (opens in a new tab)
Free usage allowance
500 images. API says 180 days after activation; central pricing says 90 days from latest activation, release or approval. Actual entitlement unresolved.Source for Free usage allowance (opens in a new tab)

The competing 180-day term is from this model’s API guide.

Output billing
Input is free; successfully generated output images are billed.Source for Output billing (opens in a new tab)
Maximum prompt characters
75Source for Maximum prompt characters (opens in a new tab)

Prompt characters beyond the limit are truncated. This is not a token count.

Image styles
<auto> (default), <3d cartoon>, <anime>, <oil painting>, <watercolor>, <sketch>, <chinese painting>, <flat illustration>Source for Image styles (opens in a new tab)
Required request fields
prompt and sketch_image_url.Source for Required request fields (opens in a new tab)
Image input limits
Sketch: 256–2,048 pixels per side, up to 10 MB. Match the square output aspect ratio to avoid stretching; white background recommended.Source for Image input limits (opens in a new tab)
Input image formats
JPG, JPEG, PNG, TIFF, WEBPSource for Input image formats (opens in a new tab)
Image URL requirements
Public HTTP(S) sketch URL without Chinese characters.Source for Image URL requirements (opens in a new tab)
Output resolutions
768 × 768Source for Output resolutions (opens in a new tab)

The explicit size field says only 768*768. A sample error lists unrelated 1024/720/1280 sizes; those are not added to the supported list.

Images per request
1–4 outputs; default 4Source for Images per request (opens in a new tab)
Sketch controls
sketch_weight: integer 0–10, default 10; larger values follow the sketch more closely. sketch_extraction=false by default; true extracts edges from an RGB image and disables sketch_color.Source for Sketch controls (opens in a new tab)
Sketch brush colors
With extraction disabled, sketch_color lists RGB brush colors; other colors are background. Default empty list.Source for Sketch brush colors (opens in a new tab)

Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

Data & enterprise terms

Generated links expire after 24 hours; input retention, training use and account-specific access remain unverified.

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

What the measurements say

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

Classification inference: separately named native Alibaba hosted release; the reviewed API and card expose service access without model weights. No exact public checkpoint for this named release is identified by the reviewed model sources. Hosted checkpoint lineage is unverified; public Wan releases and style presets are not assumed equivalent.
