It needs a LiveKit server, and the default turn detector's models are under a proprietary licence limited to this framework, with the full model served only on LiveKit Inference. No approval primitive or prompt-injection guidance was found.\n\n**Ultravox Realtime API.** Flat $0.05 a minute including model and built-in voices. No MCP server.\n\n## Before you call either\n\n### LiveKit Agents\n\n1. Set `LIVEKIT_URL`, `LIVEKIT_API_KEY` and `LIVEKIT_API_SECRET` before starting. Every agent joins a LiveKit room, on LiveKit Cloud or a self-hosted server\n2. Pass `inference.TurnDetector(version=\"v1-mini\")` to keep turn detection local, and read `MODEL_LICENSE` before using LiveKit's turn models anywhere but LiveKit Agents\n3. Pass `record=False`, or a dict per category, to `session.start()` if audio, transcripts, traces and logs must not reach LiveKit Cloud\n4. Call `context.disallow_interruptions()` first in tools that write, and set `on_duplicate=\"reject\"` or `\"confirm\"`. Duplicates are matched by tool name only, not arguments\n5. Wrap MCP servers in `mcp.MCPToolset` with `allowed_tools` (Python only). The `mcp_servers` parameter is deprecated\n\n### Ultravox Realtime API\n\n1. Honour `Retry-After` on 429 and 503 when creating calls\n2. Pin the model string (`ultravox-v0.7` or `ultravox-v0.6`) rather than relying on the default\n3. Hand clients the `joinUrl`, never the API key\n4. Delete calls through the API when you need data removed, there's no retention setting\n5. Use call stages for multi-step flows instead of one long prompt\n\n## Questions\n\n### Which is better for AI agents, LiveKit Agents or Ultravox Realtime API?\n\nLiveKit Agents scores 72.5 (BB) on agent readiness against Ultravox Realtime API's 58.5 (C), and leads in 6 of 7 scored categories.\n\n### Can an agent call LiveKit Agents and Ultravox Realtime API without installing anything?\n\nNo hosted endpoint is listed for LiveKit Agents. Ultravox Realtime API has a hosted endpoint at https://api.ultravox.ai/api.\n\n### Are LiveKit Agents and Ultravox Realtime API open source?\n\nLiveKit Agents is open source (Apache-2.0 for the framework and plugins. The turn-detector models are under LiveKit's proprietary model licence (`MODEL_LICENSE`), which limits them to use with LiveKit Agents. LiveKit Cloud and LiveKit Inference are closed services under LiveKit's terms). No open-source release is listed for Ultravox Realtime API.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/livekit-agents-vs-ultravox.json, and with the fewest tokens: https://www.anchorterminal.com/compare/livekit-agents-vs-ultravox.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"livekit-agents\", \"b\": \"ultravox\"}`.
