What is a replica?
A replica is a realistic AI avatar that can speak, listen, learn, and respond like a real person. With Tavus, you can create a replica that looks and behaves like you—or use a stock replica to generate conversations instantly. Replicas are designed to capture natural expressions, tone, and presence, making interactions feel more human and engaging. Replicas are generated using our Phoenix-4 model, built on advanced research in real-time human rendering and trained on large-scale conversational data to model natural expression, emotion, and behavior.Custom Replicas
You can create a replica in one of two ways:- Upload a training video – Record a 1-minute video with 30 seconds of speaking followed by 30 seconds of listening. This method provides the highest quality and most control. With this short input, Tavus can reproduce appearance with high fidelity, voice, expressions, and accurate lip-sync. See Training from a Video.
- Upload an image – Upload a photo of a person or character, and Tavus will automatically generate the training data and create the replica for you. This path is faster to set up but lower fidelity than video. See Training from an Image.
Creating a Custom Replica is only available on the Starter, Growth, and Enterprise plans.
Stock Replicas
Alternatively, Tavus offers 100+ ready-to-use stock replicas recorded using real actors - great for quick prototyping, demos, or teams without access to custom training footage or images.Key Features
Realistic Face Cloning
Custom replicas capture a person’s look, expressions, and speaking style.
Emotional Control
