Cartesia Managed Agents combine Ink-2, an LLM you choose, and Sonic-3.6 in a realtime voice agent. Your agent handles turn-taking and interruptions, streams audio, and can use tools during a conversation. Create and test an agent in the Playground, or manage the same agents through the API. Connect it to your application over WebSocket or give it a phone number.
