The full stack for interactive intelligence
Try CartesiaThe fastest models you can trust.
Our models are designed for live, synchronous interactions, built on State Space Models (SSMs). A new primitive for large-scale foundation models, SSMs deliver ultra-low latency, long-context reasoning, and greater efficiency at scale.
Voice agents as fast and accurate as the models powering them
Our voice agents are designed for live, synchronous interactions, built on our Sonic and Ink models. Enterprise-grade from the ground up, they integrate with your existing systems, handle complex conversations, and deploy at any scale.
The fastest, most customizable platform for building and shipping enterprise voice agents, powered by our models.
Pioneering AI research: architectures that learn through interaction
Our team has pioneered breakthrough AI architectures, including state space models (SSMs), Mamba & H-Nets. Our research manifests our mission — we architect AI that learns from and interacts with the world like humans do.
Our research
Deploy AI anywhere. Own it everywhere.
The same models and agents across cloud, on-premise, and on-device. Inference runs in-region — keeping you within your latency envelope, data residency obligations, and compliance frameworks.
Deploy via regional API endpoints across the globe — ensuring in-region processing, high availability, and the uptime your production systems demand.
Deploy in your VPC, on your own hardware, or directly in your customer's environment — with complete ownership and control over every layer of your deployment.
Deploy at the edge, directly on-device across mobile, PC, robotics, and beyond. Your data stays where it lives — fully private, instantly accessible, and always on.
