Tavus's own test: nearly half of testers took its AI avatar for human
Tavus's own study found 48% of participants took its Griffin avatar for a human after a one-minute call, far above prior systems, but the numbers come from the vendor.

After a one-minute video call, 48 percent of participants believed Tavus's AI avatar Griffin was a real person — the result of Tavus's own study.
Previous systems topped out at a two percent mistake rate in comparable tests, nowhere near this level of realism. Griffin is a real-time video conversation model from the San Francisco startup, released around September 30, processing speech, facial expressions, tone and gestures while generating video, per The Decoder's October 1 report.
Tavus also cites a test it describes as independently run by Nvidia: Griffin scored 3.83 on how human it feels, close to 3.92 for actual humans, with the previous best AI at 2.80. Only a preview called Griffin-Lite is available to select testers; the fuller version waits until safety concerns are addressed.
