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: a separately documented native image API release has no exact checkpoint in the reviewed official Wan-AI public-weight inventory. Public Wan video checkpoints are not evidence of the image model weights. Private lineage, parameters and architecture remain unknown.
