The same article gives a 95-second prompt example. Plan limits and that illustrative request conflict, so no universal 95-second maximum is asserted.

Access & pricing

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

No pinned model selector established for this access path.

Access
Historical launch only; current version-pinned access and price not established.
Regions
Not established for this endpoint; account availability is not a data-residency guarantee.

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

Data & enterprise terms

Stability terms permit using content to improve services and describe a training opt-out. This is not a default no-training or zero-retention guarantee. Partner contracts may differ; enterprise terms must be verified separately.

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

Original hosted Stable Audio music product, trained with AudioSparx and distributed through its web service. The later Stable Audio Open checkpoint is a separate release and dataset; no public weight distribution for this original commercial release was established.
