What Is a Replica?

A Replica is a hyper-realistic AI-generated video avatar created using Phoenix, Tavus’s rendering model. Phoenix is built on a Gaussian‑diffusion architecture. The latest version, Phoenix-3, enables full-face rendering with dynamic emotion control, capturing every microexpression, movement, and emotion in real time. With just 2 minutes of training video, Phoenix-3 can accurately reproduce a person’s appearance, voice, expressions, and movements with studio-quality fidelity, precise lip sync, and consistent identity preservation.
For guidelines and best practices on replica training videos, see the Replica Training article.
