Retired with the public China platform on September 3, 2026. Requests could be served by a Yi model or a named third-party model; this is not a pinned Yi checkpoint endpoint.

Rate conditions
Later documentation price for a mixed-model routing service, billed on input plus output tokens. Public service has stopped. Not a pinned Yi checkpoint price; no current inference offer.
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 for this named proprietary API/research variant from the developer’s release description and public weight inventory. Exact weights for this variant were not found. Public Yi, Yi-1.5, Yi-Coder and Yi-VL checkpoints remain excluded; API naming alone does not prove an independently trained base.
