Griffin is the first Human Interaction Model (HIM). On live video calls, 48% of people who talked to it thought it was a real person.

Today we’re introducing Griffin, our first Human Interaction Model (HIM). HIMs are a new class of models designed to understand and generate face-to-face real-time human interaction. They listen while they talk, and they pay attention to expressions and pauses, not just words.

Griffin builds on our earlier research into real-time perception, conversation and expressive human-like video. It combines those model capabilities into one, unified video-to-video system.

Griffin is the first model to pass the real-time, video Turing test. In a live study, 48% of participants who talked with Griffin thought they had talked with a real human. Previous systems, including Tavus’s own industry leading conversational video interface (powered by Phoenix 4.5, Sparrow-2, Raven-1), had a max 2% pass rate. This represents a huge breakthrough in human-machine understanding, and is only possible due to Griffin’s video-to-video duplex approach with audiovisual generation, movement, conversational modeling – all in one system, operating in real time.

Griffin-Lite, a research preview, is available today to a select group of early testers, with a wider release of a more powerful model to follow. This post covers what Griffin can do, how we built it, how we measured it, our approach to safety and what comes next.
