Data & enterprise terms
Enterprise customers may opt into ZDR for TTS/STT inference content; operational metadata is retained. Voice cloning and fine-tuning are excluded. General terms permit model improvement/training unless separately agreed or an opt-out is processed.
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
Service terms prohibit downloading or distributing the hosted models and reserve provider model rights. These Sonic/Ink service variants are not in the reviewed official public-weight inventory. Classification is specific to the served variant: public Rene, Llamba, Mamba and H-Net weights are excluded; Ink Whisper is a provider-specific derivative, not a reclassification of baseline Whisper.
