Fit and safety

Watch out

  • Good for natural, low-latency calls where tone matters and you want one per-minute price with no separate LLM bill.
  • HIPAA BAAs, SLAs and VPC deployment are Enterprise-only.

How it works

  1. Single speech-to-speech model rather than a transcribe → LLM → TTS cascade.
  2. Tool types: webhook, WebSocket and context tools, sync or async.
  3. Deploy with the agent builder, webhooks, WebSockets or LiveKit.
  4. SDKs: TypeScript and Python, plus a CLI, MCP server and agent skills (per the docs index).
  5. 51 supported languages per the docs (the launch post says 50+), with mid-conversation switching that keeps the same voice.
