Access & pricing

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

Provider account and authorized service access required. Public documentation reviewed; no paid inference performed.
Regions
Native open.bigmodel.cn service. Account eligibility and deployment region require provider confirmation; international Z.ai terms are not assumed.

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 exact named native model service in the official BigModel catalog and API or managed-service documentation, cross-checked against the developer’s public-weight inventory. No weights for this exact release were found in that inventory. A paid endpoint alone is not the basis: downloadable GLM releases and uncertain aliases are excluded pending exact mapping.
