Description
Cartesia is developing AI that learns and interacts in a manner similar to humans, moving beyond data curated by humans to AI that learns directly from the world and improves with each interaction. Their core offerings include Sonic, a text-to-speech model, and Ink, a speech-to-text model, both purpose-built for voice agents and designed for real-time, synchronous interactions.

Sonic-3.5 is highlighted as the #1 real-time speech generation model, capable of producing natural and expressive voices, including laughter, across more than 40 languages. Ink-2 is recognized as the fastest and most accurate streaming transcription model. These models are built on State Space Models (SSMs), a primitive for large-scale foundation models that enables ultra-low latency, long-context reasoning, and enhanced efficiency.
The company provides a full stack for interactive intelligence, enabling the creation of voice agents that are as fast and accurate as the underlying models. These voice agents are enterprise-grade, designed to integrate with existing systems, manage complex conversations, and deploy at any scale. The Line platform further simplifies the process of building and shipping these voice agents.
Cartesia's research focuses on pioneering AI architectures, such as state space models (SSMs), Mamba, and H-Nets, aiming to create AI that learns and interacts with the world like humans. Their solutions are deployable across cloud, on-premise, and on-device environments, ensuring data residency, compliance, and low latency through in-region inference.
Industries such as finance, healthcare, and government can leverage Cartesia's technology for applications like fraud detection, real-time outbound verification calls, and customer support voice agents that enhance security and streamline operations. The company emphasizes a commitment to building the future of interactive intelligence and invites potential users to try their platform or connect with their sales team.
