Generates short sound effects and background music from text. A second route accepts timed, overlapping sound events using the same audio1.0 model selector.
Integer; omitted or zero generates a random seed. Provider describes a fixed seed as deterministic; cross-version reproducibility is not established.Source for Seed control (opens in a new tab)
Request mode
POST a native task; poll /ent/v2/tasks/{id}/creations or supply callback_url. States include created, queueing, processing, success and failed.Source for Request mode (opens in a new tab)
Task callbacks
Processing, success and failed events; failed terminal callback delivery retries up to three times. Validate the documented callback signature.Source for Task callbacks (opens in a new tab)
Timed sound events
Events can overlap. Each event prompt is limited to 1,500 characters; from/to must fall within [0, duration]. The documented string field and placeholder example leave exact event serialization unclear.Source for Timed sound events (opens in a new tab)
International: USD 0.05 up to 5 seconds, USD 0.10 above 5 through 10 seconds. Mainland labels are strictly “less than 5” and “less than 10”; boundary handling is unresolved.Source for Published price (opens in a new tab)

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 closed-weight classification inference from the named Vidu hosted model, official API/research descriptions and operator proprietary-service terms. Public client code and inference libraries are not model weights. Exact private/public checkpoint lineage remains unverified.
