Rotate first. A nonempty output_ratio overrides scale and offset settings. Otherwise, a scale above 1 takes precedence over offsets. Offsets apply when no ratio or expansion scale is set and at least one offset is above 0.Source for Expansion setting priority (opens in a new tab)
Generation controls
angle: counterclockwise integer 0–359, default 0. Rotation alone excludes 90, 180 and 270 degrees; those are allowed together with valid expansion. x_scale/y_scale: 1–3, default 1. output_ratio: empty (default), 1:1, 3:4, 4:3, 9:16 or 16:9.Source for Generation controls (opens in a new tab)
Added padding limits
Offsets default to 0. Added top + bottom padding must be less than 3 × input height; left + right must be less than 3 × input width. These constrain added padding, not final dimensions.Source for Added padding limits (opens in a new tab)
best_quality=false by default; true takes longer. limit_image_size=true by default. The security filter cannot process outputs above 10 MB. add_watermark=true by default adds a lower-left AI-generated mark.Source for Quality and watermark controls (opens in a new tab)

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
Qualified classification inference: a separately named native Alibaba hosted model/API. Reviewed official sources document inference access but identify no exact downloadable checkpoint. This does not prove that no public release exists; private checkpoint lineage remains under review. Public Wan weights and research model sizes are not assumed equivalent.
