Training source requirements, not generated output limits.
trainingAccess
Supply one public/presigned training URL accessible for at least 24 hours after submission. Image training requires a stock voice_name or default_voice_id, not both. Video training derives a voice from the recording.Source for trainingAccess (opens in a new tab)

Data & enterprise terms
Default privacy terms permit service improvement and AI research/training. Biometric retention is limited by the stated purpose or one year after last interaction, whichever comes first. Enterprise zero-retention arrangements are separate; no universal zero-retention promise is inferred.
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.

AVSR
Tavus · provider-reported
0.261score
Same paired internal test set; both models fine-tuned. Provider evaluation, not an independent cross-provider ranking. AVSR/CSIM higher is better; FID/FVD lower is better; ΔP describes motion vividness.

The record behind the model
Why it is included
Named model developed by Tavus in its proprietary hosted/research stack. Reviewed primary documentation provides no downloadable weights for this model; service terms restrict source derivation and independent avatar use. Open SDKs and third-party models in the surrounding pipeline are separate.
