Cartesia

We're hiring for our first ever Deployed Engineer at Cartesia! Voice AI has been on fire this year and this is a unique role for someone who loves solving technical problems and being a trusted advisor to all our customers and partners. It's a rare chance to work across every function, most closely with Cartesia's founders and my amazing colleagues Ryan Lipsky Timothy Luong Sauhard Jain and see how voice is transforming every industry.

Today, we’re excited to introduce three state-of-the-art models that work together to transform human-AI interactions: ?? Phoenix-3: Our flagship replica model, now with full-face rendering, emotions, & micro expressions ??? Raven-0: A real-time perception system, giving AI human-like eyes to understand visual context and emotions ??? Sparrow-0: A transformer-based turn-taking model for natural dialogue and turn-taking You can now build even more realistic AI Agents with emotional intelligence. They not only look human, but can engage, perceive, listen, and understand in a deeply human way. This is an evolution of our Conversational Video Interface, into a complete operating system for human-AI interaction. AI isn’t just responding anymore. It’s thinking, perceiving, and evolving – it's a big step closer to feeling like true face-to-face communication. See the magic for yourself—talk to our live demo agent Charlie: www.tavus.io We can’t wait to see what conversational AI video experiences you build with CVI. ??

Humans evolved wired for face-to-face interaction—reading subtle expressions, body language, and emotion instinctively. This multi-channel communication is fundamental to how we connect and understand each other. Yet, the current state of human-machine interaction is anything but that- bad chatbots, shitty IVR systems, it’s a regression. We’ve adapted ourselves to technology’s limitations instead of demanding technology that meets us on our terms. That changes today. I’m thrilled to share a huge leap forward for CVI (Conversational Video Interface), powered by three SoTA models and systems from our research team. These come together to bridge the human-machine divide by allowing machines to see, listen, react, and engage the way we prefer: face-to-face. Here’s what we’ve delivered: ??? Raven-0, a first of it’s kind perception system designed to see the world the way humans do- by continuously processing visual scenes, by using context to perceive. Allowing it to understand everything from what you’re sharing on your screen, to the environment around you, to rich emotional understanding that goes well beyond basic emotion labels. ?? Sparrow-0, a best-in-class conversational turn-taking model that uses semantic and conversational understanding to create a natural rhythm of speech that feels effortless. No more getting interrupted by AI or having to think about how to talk to it. ???? Phoenix-3, a complete overhaul of our replica model. It uses a groundbreaking gaussian-diffusion method to deliver full-face rendering, micro-expressions and emotions with improved fidelity and identity, while being realtime. AI should enhance human experience, not strip it away. Imagine an AI therapist who can perceive the unspoken emotions behind your words and facial expressions. A tutor that adapts in real-time to a student’s confusion. A customer service agent that actually listens and responds with empathy. We’re excited to provide the OS for human-AI interaction to power these futures. See for yourself—talk to Charlie, our live demo to try out the new models: www.tavus.io This is just the beginning. The gap between humans and machines will not be bridged by intelligence alone—it must be bridged by teaching machines to communicate and understand us. Let’s build it together. ??
