Nearly half of test subjects mistook Tavus' AI video avatar for a real person on a one-minute call
Tavus launched Griffin, a real-time conversational video model that 48% of test subjects mistook for a real human on one-minute calls.
Tavus introduced Griffin, billed as the first "Human Interaction Model" (HIM), processing speech, facial expressions, tone, gestures, and pauses while generating real-time video conversation. In Tavus testing, 48% of participants believed Griffin was a real person after a one-minute call, versus a 2% maximum for previous systems. An Nvidia test of perceived humanness scored Griffin 3.83 versus 3.92 for actual humans and 2.80 for the previous best AI. Griffin-Lite is available as a research preview, with a fuller release gated on addressing safety concerns; the San Francisco startup has raised about $64 million.
