Access & pricing

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: this separately named native image API is not an exact checkpoint in the reviewed official Wan-AI inventory. Public Wan2.1 T2V weights can also perform text-to-image generation, so task overlap alone neither proves equivalence nor proves private weights. The specific hosted Plus/Turbo/Flash/editing checkpoint lineage remains unverified; public video architecture and parameter counts are not copied.
