ref_strength: 0–1; no verified default. ref_mode: repaint (default, content) or refonly (style). seed: 0–2,147,483,647; omitted seed is random, and multi-image outputs use successive seeds. Reuse improves stability, not a guarantee of identical output.Source for Generation controls (opens in a new tab)

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.
