Vidu’s drama-focused reference-video variant. Native documentation distinguishes direct references and reusable subjects, with differing limits across the two API markets.
Submit a native task and poll /ent/v2/tasks/{id}/creations, or provide a signed callback URL. JSON task envelopes are not evidence of LLM structured-output support.Source for Request mode (opens in a new tab)
Task callbacks
Processing, success and failure events. Terminal callback delivery is retried up to three times. HMAC-SHA256 signature uses the provider-documented canonical string, signed headers, date and nonce.Source for Task callbacks (opens in a new tab)
Default five concurrent tasks per organization, shared across API keys; excess tasks queue. Purchased plan and system load can change effective concurrency.Source for Request quotas (opens in a new tab)
Usage metering
Generated-video seconds, with prices dependent on route, resolution, account market and eligible off-peak mode. Not a text-token or per-question tariff.Source for Usage metering (opens in a new tab)
Regional credit values are separate provider prices, not a foreign-exchange conversion.
Off-peak generation
Off-peak is false by default. Provider promises completion within 48 hours or automatic cancellation with credit refund. Manual cancellation is available before disallowed task states; the cancellation API shows scheduled tasks cannot be cancelled. Off-peak scheduling is not evidence of a discounted batch API.Source for Off-peak generation (opens in a new tab)
Voice references
Mainland direct-reference contract documents 0–3 MP3 samples, each 3–12 seconds and at most 50 MB; 20 MB total request body. International direct-reference section does not document sounds.Source for Voice references (opens in a new tab)
Reusable subjects
Reference route supports image/text subjects, @name references, optional saved server_id and temporary images. q2-pro video-subject examples in the shared schema do not establish video input for Q3.Source for Reusable subjects (opens in a new tab)
Access & pricing
Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

The API exposes off_peak, but international pricing limits reference discounts to Q3/Turbo; no Ad/Drama discount is quoted.

Published price only: this resolution is NOT listed as supported in the reviewed variant API.
International privacy policy states personal data storage in Singapore and retention for legal/operational purposes. It does not establish inference residency, zero retention or a no-training guarantee. Creation links last 24 hours.

Requested integer 2–15 seconds; default 5. Actual output may be shorter or longer to complete the story; billing uses actual output duration.Source for Video duration (opens in a new tab)
Only successful output is billed per generated video second. No input-media tariff is published for these routes. Actual duration may differ from the requested duration.Source for Output billing (opens in a new tab)
The reference API explicitly states that Drama is billed on actual generated duration.
540P default prose says 1024*576 but the valid-size table says 960*528 for 16:9. Preserve this conflict; do not silently substitute the text-to-video size table.

Rate conditions
Published original Beijing rate for vidu/viduq3-drama_reference2video. Promotions excluded; no free quota. Only successful output seconds are billed. Drama outputs audio and actual duration may differ from the request. Do not apply native Vidu credit, per-clip or off-peak formulas to this hosted rate.
Vidu is the inference provider. The Beijing API region and 24-hour output-link lifetime do not establish inference data residency, input retention, training use or deletion policy.
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.

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 a separately named Vidu native hosted model and operator terms reserving proprietary service rights. Public API clients and efficiency libraries do not establish downloadable weights. Exact checkpoint lineage remains unverified.
