Data & enterprise terms

Terms state customer content and usage data will not be used by Akool or third parties to train machine-learning models. Privacy policy gives Customer Content a 365-day retention period with user deletion, and AWS storage in the EEA or US unless otherwise specified. Generated-resource expiry is separate from storage retention. Contract-specific and legal exceptions apply.

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

Documented named hosted service, product or voice-engine selector. The underlying native checkpoint is undisclosed or explicitly supplied by a third party, so this record does not assert independent proprietary Akool weights.
