Tavus Unveils Phoenix-3, Raven-0, and Sparrow-0: The Future of AI-Powered Video Agents

On March 6, 2025, Tavus, a leading AI research company backed by Sequoia, introduced three new AI models—Phoenix-3, Raven-0, and Sparrow-0—marking a major leap in human-AI interaction. These models power the next version of Tavus’ Conversational Video Interface (CVI), enabling emotionally intelligent, hyper-realistic video agents.

Meet the New AI Models

🔥 Phoenix-3 – The first full-face AI rendering model using Gaussian-diffusion animation.

• Generates real-time micro-expressions (eye movements, brows, cheeks) to match emotions.
• Unlike standard lip-syncing models, it animates the entire face, making AI interactions incredibly lifelike.

🦅 Raven-0 – The first AI perception model that sees and reasons like a human.

• Provides continuous visual understanding—interpreting actions, text, and surroundings in real time.
• Detects user expressions (confusion, smiles) and adjusts responses dynamically, adding emotional depth to AI conversations.

🐦 Sparrow-0 – A state-of-the-art conversational turn-taking model that eliminates robotic dialogue timing.

• Built on a custom transformer architecture, it adapts to natural speech rhythms.
• Responds instantly in fast-paced talks or pauses thoughtfully—making AI feel more human.

What This Means for AI Interaction.

These models work together to power Tavus’ Conversational Video Interface (CVI), allowing developers to create video agents that feel truly human.

Demo Persona: "Charlie"

• Showcases all three models in action.
• Functions as an AI researcher, capable of:
  ✅ Web searches
  ✅ Image generation
  ✅ Technical support via screenshare
  ✅ Role-playing various scenarios

Users on X say Charlie’s ability to express emotion and respond in real time moves AI past the "uncanny valley" into natural interaction.

Industry Adoption & Availability

🔹 Companies like CVS, Alibaba, and Deloitte, along with startups like Delphi and Mercor, are already leveraging Tavus’ AI models.
🔹 Charlie’s demo is now live on the Tavus homepage.
🔹 Developers can start building with these models today.

What People Are Saying

📢 “Next-level AI”
📢 “A complete OS for human-AI interaction”
📢 “This changes everything about how we talk to AI”

Tavus’ CEO, Hassaan Raza, says the goal is to merge emotional intelligence (EQ) with the intelligence & scalability of AI—and based on early reactions, they’re delivering on that vision.
