Access & pricing

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

Access
Present on price list but absent from current API enum. Historical identity retained; current access requires provider confirmation.

Data & enterprise terms

Retention, training use, regional processing and enterprise terms have not been summarized for this endpoint.

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 from the provider’s named proprietary API or internally trained research release, checked against its public weight inventory. No exact weights for this variant were found; similarly named open-weight Baichuan releases are excluded.
