What our customers say

Join the growing list of companies opting for Sonic.

"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."

Russ d'Sa CEO & LiveKit co-founder

“Cartesia Sonic is the best voice model today for real-time multimodal use cases. At Daily, we've been working extensively with open source developers and enterprise customers building with text to speech. It's exciting to see the innovations unlocked by Cartesia's state-of-the-art research, and its combination of high quality, flexibility, fast response, and reasonable cost. It's unlocking new voice AI use cases for Daily Bots developers building in experiences like customer support, appointment scheduling, and interacting with virtual personas. We couldn't be more excited to partner with Cartesia.”
