Tavus OS for Human-AI Interaction

Introducing Phoenix-3, Raven-0, and Sparrow-0 — a family of models powering a modular OS for rendering, perception, and cadence in real-time human-like AI interactions. The goal is to bring a human dimension to AI agents that can see, hear, respond, and look human during video-based conversations.

What it is

The Conversational Video Interface (CVI) is designed to enable AI agents to engage people as if in live, human conversations. It supports scalable deployment of digital twins or stock replicas to interact with users across geographies and languages, without being limited by human availability.

Core capabilities

• Full-stack operating system for AI agents that orchestrates face rendering, vision, speech, and emotional intelligence into natural, human-like conversations.
• Easy plug-in of any LLM, Retrieval-Augmented Generation (RAG), or Text-to-Speech (TTS) system.
• High realism in facial animation, natural movements, micro-expressions, and real-time emotional responsiveness.
• Real-time perception and context-aware interaction via perception models that understand visual cues and environmental context.

Models

• Phoenix-3 — Advanced full-face rendering with lifelike animation, identity preservation, micro-expressions, and real-time emotional response.
• Sparrow-0 — AI that understands the rhythm of conversation, monitors tone and pacing, and maintains human-like timing in replies.
• Raven-0 — Perception model that goes beyond typical computer vision, continuously processing visual context, reading emotions, and responding intelligently to the environment.

Use cases

• Healthcare: Physician assistant, symptom analysis, real-time medical documentation support.
• Tutoring: 24/7 personalized lessons in any language, adapting to learning styles.
• Recruitment: AI interviewer to screen candidates at scale with engaging experiences.
• Executive coaching and therapy: 1:1 coaching and emotionally aware conversations.

How it works

• Build AI agents that can see, hear, and talk via a video chat interface.
• Deploy thousands of digital twins or stock replicas to interact with users regardless of geography or language.
• Swap in preferred LLMs, RAG, or TTS modules as needed.

Real-world validation

• Customers report that CVI delivers a more authentic, human-like interaction, enabling realistic interviews, coaching, and mentorship experiences.
