Introduction
We're excited to announce that Cartesia Sonic TTS is now available on Together AI's AI acceleration cloud. Together AI's focus on fast, affordable AI development aligns with Cartesia's goal of delivering cutting-edge, real-time AI models. This partnership enables the thousands of developers using the Together API to access our advanced voice models directly on their platform.
Together AI partners with Cartesia to deliver the fastest voice API
Our partnership with Together AI began when we were first bringing Sonic to market by serving on Together GPU clusters. Now, we're excited to make Sonic available to Together AI's community of over 300K developers via Together AI's development platform.
Together partnered with Cartesia because Sonic's State Space Model architecture aligned with their vision to make AI model development faster, cheaper, and production-ready.
Ultra low latency: With just sub-90ms streaming latency - half the time of a human blink - Sonic delivers the fastest end-to-end voice applications (STT → LLM → TTS) available today, with continuous performance gains on the horizon.
Superior content processing: Masters complex inputs like phone numbers and technical terminology with striking accuracy, while offering diverse voice options across 15 languages.
Leading Voice AI research: The key to Cartesia's performance breakthroughs is their innovative State Space Model (SSM) architecture, achieving major breakthroughs in voice realism, personalization, and efficiency.
Enterprise Scalability: Production-ready infrastructure reduces development time and operational costs for large-scale deployments.

"This partnership represents a transformative moment in enterprise AI adoption. By combining Rasa’s strengths in enterprise conversational AI with Cartesia's innovative voice technology, we're fundamentally changing how enterprises can deploy and scale AI assistants across their organizations."
Melissa Gordon, CEO of Rasa
"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.”
