Billing basis
Uses Descript AI credits from a shared plan allowance; exact cost depends on selected model, media length and operation. Provider-native token/character tariffs do not apply to this host.Source for Billing basis (opens in a new tab)
Recorded consent statement required; existing clones cannot receive more training samples. Community stock voices can disappear at their owners’ discretion.
One-time automatic switch to v4 on opening a project after availability; later manual choices persist. Existing generated audio is not regenerated.Source for Model routing (opens in a new tab)

Data & enterprise terms
Descript help states that production models use no Descript user data; internal research/development uses data only from users who opted in. Enterprise data sharing is disabled by default. Partner agreements prohibit using submitted data to train partner AI. This is not a blanket zero-retention promise; project storage and deletion have separate policies.
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
ElevenLabs-developed managed model. Reviewed release documentation supplies service access and no downloadable weights; proprietary speech, transcription and turn-taking families are explicitly described by the provider.
