About
GPT-Live is a new generation of voice models for natural human-AI interaction, now powering ChatGPT Voice. It is built to make talking with AI feel much more like having a real conversation through a full-duplex architecture, meaning it can listen and speak at the same time. During conversations, GPT-Live can show it is paying attention with short acknowledgments like “mhmm” or “yeah,” engage in quick back-and-forth, or stay quiet when the user needs a moment to think. Instead of processing separate turns one after another, GPT-Live continuously processes input while generating output, allowing it to decide many times per second whether to speak, keep listening, pause, interrupt, or invoke a tool. For questions that require web search, deeper reasoning, or more complex work, GPT-Live can delegate to a frontier model behind the scenes and bring the result back into the conversation when it is ready, while still maintaining the flow of the voice interaction.

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.
