Access & pricing

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

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

Inference from the exact named production model or managed service in Kuaishou’s official API catalog: no downloadable production weights or open-weight license were established for this identity. Original public-weight Kolors and research derivatives are excluded; public demo code is not evidence of production weights.
