LiveKit Agents: Real-time media infrastructure platform with an integrated agent framework for building voice and video AI assistants that can participate in live conversations. Enables developers to create AI agents that can see, hear, and speak in real-time video calls, with support for spatial audio, screen sharing, and multi-participant interactions.
LiveKit Agents is an open-source framework for building real-time, multimodal AI agents that can see, hear, and speak. Built on top of LiveKit's WebRTC infrastructure, it provides the transport layer and developer framework needed to create voice agents, video AI assistants, and other real-time AI applications that interact with users through audio and video streams rather than just text.
The framework's architecture centers on a worker process model where agent code runs as "workers" that connect to LiveKit rooms. When a user joins a room, the agent worker is dispatched to participate alongside them, receiving audio/video tracks and sending responses back in real-time. This design handles the complex WebRTC plumbing — media encoding/decoding, network adaptation, echo cancellation — so developers can focus on the AI logic.
