Tavus introduces Griffin, a Human Interaction Model designed for real-time face-to-face communication that understands expressions, pauses, and non-verbal cues alongside words. In testing, 48% of participants believed they were talking with a human, vastly surpassing previous systems. Griffin-Lite is available to early testers, with a wider release planned.
Prelulu is a consumer AI companion app offering text, voice, and video calls with fictional characters, positioned as an alternative to Tavus Griffin, which is a restricted research-preview model for developers. Prelulu focuses on relationship continuity and immediate consumer access, while Tavus Griffin targets AI builders creating video agents through limited early tester access.
