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

Inferred for this named native commercial model service from its official access documentation and comparison with Tencent’s published model-weight inventory. No weight release for this exact service was found in the reviewed inventory. This is not a claim that every Tencent model is closed or that the provider has disclosed the underlying checkpoint. Public Hy3, Hy4, Hy-MT2 and HunyuanImage 3.0 releases are excluded.
