Tavus uses the Conversational Video Interface (CVI) as its end-to-end pipeline to bring the human layer to AI. CVI lets you configure your PAL’s behavior, then combine it with a face, which defines the on-screen likeness and voice.
Terminology update: Tavus now uses PAL (behavior, knowledge, and pipeline configuration) and Face (visual appearance and voice) in the API and docs. Legacy names persona and replica still work on existing endpoints and request fields (/v2/personas, /v2/replicas, persona_id, replica_id, and related aliases) for backward compatibility.
