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

No public model-specific API selector or immutable checkpoint identifier found.

Access
The research page links to a private-beta interest form. Current onboarding status is unverified; the form was not submitted. No public model-specific API route is established.

Data & enterprise terms

The public product EULA requires a separate agreement for API access and grants training rights over uploaded influences. Research beta terms may differ; no model-specific retention or residency guarantee is verified.

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

Qualified inference: AIVA identifies this as its own internally developed model in a research announcement describing selective private-beta access, while its official EULA restricts derivation of underlying technology and requires separate API agreements. Reviewed official pages provide no weight download or open license for this model. This is not an explicit per-checkpoint closed-weight declaration, and public metadata searches are not exhaustive. It is not classified solely from generated-music copyright terms.
