Tavus has unveiled Griffin, an AI system designed to conduct real-time video calls that process facial expressions, tone of voice, and gestures during conversation. The company describes Griffin as the first "Human Interaction Model."

In testing conducted by Tavus, 48 percent of participants believed Griffin was a real person after a one-minute call. This represents a substantial leap from previous systems, which achieved a maximum of 2 percent in similar deception metrics.

Griffin operates by analyzing and responding to human behavioral cues during live video interactions. The system's ability to interpret vocal tone, facial expression, and physical gesture suggests a significant advancement in the realism of AI avatar technology.

The high deception rate in Tavus's testing indicates that Griffin achieves a level of behavioral mimicry that approaches human interaction patterns closely enough to fool half of test subjects in brief exchanges. The gap between Griffin's 48 percent result and the previous ceiling of 2 percent underscores the rapid improvement in video-based AI avatar technology.

The company's framing of Griffin as a "Human Interaction Model" reflects a shift in focus toward systems optimized for conversational realism rather than visual accuracy alone. This approach emphasizes the integration of multiple behavioral signals.

The implications for deployment remain unclear from available information. Applications could range from customer service and sales to remote assistance, though questions about transparency, consent, and disclosure in such interactions persist in the broader AI industry.

Tavus has not disclosed full methodology details, sample size specifics, or independent verification of these results in the available reporting.
