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 nova-tts-1
Access Provider documents service access with an eligible account and API key. No paid inference was performed.
Regions Regional deployment and account eligibility must be confirmed with the provider. Endpoint pricing has not been collected. Check the provider for applicable rates.
Data & enterprise terms Retention, training use, regional processing and enterprise terms have not been summarized for this endpoint.

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 INPUT Process & retain The system processes eligible input and retains reusable state.
02 / LATER REQUEST Check available state Reuse depends on matching input, session state and the cache policy.
03 / CACHE HIT Reuse & 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 Classification is an inference from the named native commercial service or licensed edge release, its official access documentation, and cross-checking the developer’s public-weight inventory. The named service weights were not published in the reviewed inventory. This does not classify every SenseNova model as closed: public U1, U1.5, Vision, SI, MARS, InteractiveOmni and Piccolo releases are excluded.
