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

ASD-1 is a named pipeline, not a documented public model selector.

Access
Embedded active-speaker selection in compatible Sync generation workflows. No standalone ASD-1 inference endpoint verified. Current active_speaker_detection options do not pin the ASD-1 checkpoint.
Regions
Privacy policy describes direct collection in the United States and transfers to other jurisdictions; no model-specific inference residency guarantee established.
purpose
Connect each voice to the corresponding visible face and apply lip-sync only while that person speaks.Source for purpose (opens in a new tab)
accessScope
Named in the Lipsync 2 launch. Current generation workflows expose active_speaker_detection, but that DTO does not pin ASD-1 weights. A separate public standalone inference contract is unverified.Source for accessScope (opens in a new tab)
revisionEvidence
The current schema includes a v3 boolean described as ASD v3. Its underlying checkpoint, release chronology and relationship to ASD-1 are unresolved.Source for revisionEvidence (opens in a new tab)

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

Data & enterprise terms

Privacy policy permits service improvement and AI model training/fine-tuning uses. Enterprise zero-data-retention requires a contract and provider activation; it is not a default or self-serve switch. No universal fixed deletion window is established.

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

The Lipsync 2 launch names ASD-1 as a pipeline Sync built. Its underlying weights and component identities are not disclosed, so this record is explicitly a hosted managed component rather than a claimed new foundation checkpoint.
