What our customers say

"We're thrilled to partner with Cartesia - their technology has dramatically improved the accuracy and reliability of our call center agents.

Jeffrey Liu, Founder and co-CEO, Assort Health

"Together AI's mission has always been to provide developers with the most powerful and efficient tools for building AI applications. Cartesia is leading the charge of building efficient, multimodal models from first principles, starting with their Sonic TTS model. By integrating Sonic into our platform, we're enabling developers to create sophisticated multi-modal applications that leverage the most advanced and lowest latency voice model available today, all while maintaining the simplicity and reliability our users expect."

Vipul Ved Prakash, Together AI's CEO

"Internet applications weren’t built for how we’ll use computers in the future. Those computers will see, hear, and speak like we do. We’ll interact with them like we do with each other. We designed LiveKit’s Agents framework to make it easy to build applications for this new paradigm. Cartesia—pioneers of the SSM architecture—shared our belief that real-time, multimodal AI models would be at the center of computing, making them the perfect Agents launch partner."
