Cartesia Managed Agents

Cartesia Managed Agents is Cartesia's end-to-end enterprise voice-agent platform, launched October 29, 2026. You write instructions, pick a voice and an LLM; Cartesia runs listening, turn-taking, interruptions, tool calls, knowledge retrieval, and telephony on its Ink/Sonic stack.

Key points

1. Named product: Managed Agents (not just another Sonic/Ink model bump).

3. Stack: multilingual (44 languages), webhook/client/system tools, knowledge bases, outbound batches; Playground + Agents API.
4. Pricing signal: about $0.03/min for agents (+ telephony if using Cartesia numbers).
