LiveKit Agents
LiveKit Agents is an open-source framework and managed cloud platform for building real-time voice, video, and multimodal AI agents. The SDK handles the hardest parts of voice AI—streaming STT-LLM-TTS pipelines, turn detection, interruption handling, and telephony integration—with plug-in support for all major AI providers. Developers can self-host the entire stack on LiveKit Server (the most-used open-source WebRTC server) or deploy to LiveKit Cloud. The framework is free and open source; LiveKit Cloud charges usage-based rates for hosted inference and media routing with a free tier for development.
Solid choice for most workflows
You need to build production-ready voice AI agents with real-time STT-LLM-TTS pipelines, turn detection, interruptions, and telephony without wrestling with WebRTC or low-level streaming.
Sub-100ms latency, reliable interruptions and turn detection; self-host free or use Cloud free tier (1k min/mo)—scales to fleets but requires tuning models for latency.
You want flexible deployment for voice agents—from local dev to global scale—without vendor lock-in or infrastructure headaches.
Cloud is dead simple for prod with auto-scaling; self-host needs infra ops but zero lock-in—great examples for Next.js/Streamlit frontends.
You need multimodal agents beyond voice—like robotics teleop or video processing—with low-latency sensor streaming.
Proven at Skydio-scale (robot fleets); sub-100ms but custom pipelines add complexity vs pure voice.
Cloud usage billing surprises
Free dev tier (1k agent min/mo) but prod scales with inference/media routing costs—monitor via dashboard; self-host avoids entirely.
Model tuning required
Out-of-box latency/quality varies by STT/LLM/TTS combo; needs experimentation for interruption handling in noisy/multi-speaker scenarios.
Trust Breakdown
What It Actually Does
LiveKit Agents lets you build AI assistants that handle voice and video conversations in real time, managing speech recognition, language processing, and voice output without you building those pieces from scratch.
