Provider privacy policy states ephemeral streaming audio unless enterprise asynchronous storage or custom logging is enabled; request metadata is retained 30 days, account records active tenure plus 7 years, and custom voices until deletion with a 30-day purge window. Terms restrict the no-training guarantee to paid API payloads and public foundation models, with opt-in exceptions. Pricing retention tiers and broader policy headlines need reconciliation. Lagos core infrastructure and possible London/other edge transit are described; strict Nigerian routing requires private tenancy. These are provider claims, not independent compliance certification.
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
Managed API or workflow under proprietary service terms; backing checkpoint identity is not established. Not counted as an independently verified private foundation-model release.
