API model ID
Not collected

No exact public API selector established.

Access
Enterprise model offered through contact-based cooperation; exact serving contract, public selector and prices unverified.
Regions
Native China platform. No additional regional endpoint or residency guarantee inferred.

Endpoint pricing has not been collected. Check the provider for applicable rates.

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.

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.
