Published price
Monthly plan allowances (audio hours): Free 5, Individuals 100, Pro 600, Business 4,000. Paid plans USD 29/99/499 or NGN 45,000/150,000/750,000 monthly. Overage charges are additional; the two currency schedules are published prices, not conversions.Source for Published price (opens in a new tab)

Access & pricing

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

API model ID
Not collected

No immutable serving checkpoint established.

Access
POST https://api.pisonlabs.com/v1/speech/transcribe; Bearer API key scoped per project and endpoint. Reference snippets establish example shapes, not authenticated service availability.
Regions
Policy describes Lagos core deployment with potential London/other edge transit. Strict Nigerian routing requires private tenancy.

Data & enterprise terms

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

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.
