About

Griffin is Tavus’s first Human Interaction Model, a full-duplex video-to-video system designed to understand and generate face-to-face human interaction in real time. Unlike traditional conversational systems that process speech recognition, language modeling, and speech synthesis sequentially, Griffin continuously perceives audio and video, decides when and how to respond, and generates expressive speech and video at the same time. It pays attention not only to words, but also to tone, gaze, facial expression, gestures, pauses, interruptions, and the surrounding visual context. The model can backchannel, yield or take the conversational turn, react to interruptions, remain engaged during silence, and adjust its emotional tone and nonverbal behavior as the interaction changes. Griffin generates the full visual scene from a reference image, including the face, body, hands, chair movement, shadows, and background, rather than animating only a talking head.

About

Seeduplex is a native full-duplex speech large language model built on a new “listen while speaking” framework for more natural, fluid, and precisely paced voice interaction. Unlike traditional half-duplex systems that alternate between listening and replying, it continuously receives and understands user-side audio, allowing it to listen and speak simultaneously while tracking the broader acoustic environment. Its high-precision interference suppression distinguishes genuine user interaction from background noise, broadcasts, navigation prompts, side conversations, and overlapping voices, reducing false responses and false interruptions in complex settings. Seeduplex also combines speech and semantic features for adaptive endpoint detection, helping it recognize when a user is thinking, hesitating, correcting themselves, or has actually finished speaking. It can wait patiently through reflective pauses, respond quickly once an utterance ends, and stop smoothly when interrupted.
