Privacy policy describes direct collection in the United States and transfers to other jurisdictions; no model-specific inference residency guarantee established.
delivery
Asynchronous generation with status polling or webhooks. Status notifications and faster processing do not establish real-time streaming inference.Source for delivery (opens in a new tab)
rendering
H264 via libx264, CRF 17 and slow preset. HDR normalizes to SDR; alpha channels are removed. Original bitrate, frame rate and color appearance may change.Source for rendering (opens in a new tab)
creditPlans
Hobby $5/month: 300 credits, 1 concurrent job, 1-minute max, 500 MiB files. Starter $12: 700, 5 jobs, 2 minutes, 2.5 GiB. Pro $29: 2,000, 10 jobs, 5 minutes, 2.5 GiB. Team $99: 8,000, 20 jobs, 10 minutes, 5 GiB. Organization enrollment determines billing system.Source for creditPlans (opens in a new tab)
Model-specific limits can be lower.
legacyPlans
Hobbyist $5/month: 1 concurrent job, 1 minute. Creator $19: 3 jobs, 5 minutes. Growth $49: 6 jobs, 10 minutes. Scale $249: 15 jobs, 30 minutes. Usage billed separately; Enterprise custom.Source for legacyPlans (opens in a new tab)
topUps
Credit top-ups: Hobby $0.013, Starter $0.012, Pro $0.011, Team $0.010 per credit. Consumption value of $0.01/credit does not mean every credit costs one cent to purchase.Source for topUps (opens in a new tab)
creditExpiry
Monthly credits roll over one extra billing period. Top-ups persist while subscribed; cancellation forfeits all remaining credits, including top-ups.Source for creditExpiry (opens in a new tab)
fileLimits
Application maximum 5 GiB/file, subject to lower plan and transport limits. Credit-plan caps vary. Use upload-first assets or direct media URLs; URL inputs still must satisfy applicable limits.Source for fileLimits (opens in a new tab)
batchContract
20–500 unique requests in JSONL or JSON rows, up to 5 MB. Target turnaround 24 hours. Normal generation concurrency is bypassed, but separate active-batch limits apply. Dedicated guide says Scale or Enterprise; confirm credit-plan entitlement. No blanket batch price discount established.Source for batchContract (opens in a new tab)
privacyControls
Enterprise ZDR is contract-backed and enabled by Sync. Saved assets, generation files and account policies require the applicable agreement; no blanket default deletion deadline asserted.Source for privacyControls (opens in a new tab)
Billing basis
Legacy usage is per output frame, with published per-second examples at 25 fps. Credit plans consume credits; subscriptions, top-up purchase rates and usage consumption are separate.Source for Billing basis (opens in a new tab)
costEstimate
POST /v2/generations/estimate with positive finite duration and fps (default 30). It does not inspect media. Use actual billable duration; estimatedCredits is null for dollar-billed organizations.Source for costEstimate (opens in a new tab)
Included free allowance
Free: 3 lip-sync generations/month up to 20 seconds; at most one Sync 3 up to 15 seconds. No ongoing free generation allowance after subscribing. React 1’s 15-second cap still applies.Source for Included free allowance (opens in a new tab)

Rate conditions
Published legacy subscription-plus-usage tariff; monthly subscription separate. Cash usage plan, not the newer credit plans. Bill actual processed output frames. Displayed per-second rates on the pricing page can differ slightly because of rounding; do not assume a universal 25-fps input or a credit discount.
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.
