Managed Agents is Cartesia's hosted service for building and running conversational voice agents on Ink and Sonic models.
Managed Agents turns a text agent into a conversational voice agent through a fully managed runtime with tool calling, live caller audio handling, and real-time spoken responses. Teams configure prompts, voices, languages, models, and tools such as webhooks and call transfers.
The service includes telephony with SIP trunking and Cartesia-provisioned numbers plus evaluation tooling for live testing, metrics, and call analytics. It bills at 6 cents per minute of call duration with prepaid plan dollars, serving teams scaling voice agents from self-serve to enterprise.
