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

voice or language selects a task option, not a documented immutable checkpoint.

Access
POST https://abena.mobobi.com/playground/api/v1/tts/synthesize/ (JSON text, voice, optional speed). Free usage requires no API key; authenticated use accepts Authorization: Bearer or X-API-Key.
Regions
Hosting location not disclosed; policy allows international processing.

Endpoint pricing has not been collected. Check the provider for applicable rates.

Data & enterprise terms

Hosted API privacy says audio/text are deleted after processing and are not used for training without explicit consent. Account, billing, request, performance and error logs are separately collected. Exact log retention and hosting region are unspecified; international processing and trusted service providers are allowed. This does not establish universal zero retention.

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

Commercial speech capability with undisclosed backing checkpoints. API terms reserve model ownership and prohibit extraction; the linked MIT repository supplies client examples, not model weights. This service entry does not establish that every backing artifact is independently closed-weight.
