Privacy policy describes direct collection in the United States and transfers to other jurisdictions; no model-specific inference residency guarantee established.
By April 2024, sync-1 and sync-1.5.1-beta automatically routed to sync-1.5.0. These routing aliases are not counted as additional current checkpoints.Source for legacyRouting (opens in a new tab)

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 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
Official model documentation or release history identifies a Sync-developed generative lip-sync model. The public service exposes hosted inference, while the service terms reserve proprietary technology. The founders’ separate Wav2Lip open-source work does not establish that these model weights are public.
