This project provides a Node.js framework for building real-time, multimodal AI agents, enabling developers to create conversational voice agents that can process audio and text inputs. It's targeted at developers looking to integrate advanced AI capabilities into real-time communication platforms, offering a server-side participant framework.

How It Works

The framework utilizes a worker-based architecture where server-side processes (workers) manage and orchestrate AI agents. Agents are defined as functions that can compose various plugins for specific tasks like Speech-to-Text (STT), Large Language Models (LLM), and Text-to-Speech (TTS). This modular design allows for flexible integration with different AI service providers. A new phrase endpointing model is available for improved turn detection.

Quick Start & Requirements

• Install core library: pnpm install @livekit/agents
• Install plugins: pnpm install @livekit/agents-plugin-openai (example)
• Environment variables required: LIVEKIT_URL, LIVEKIT_API_KEY, LIVEKIT_API_SECRET, and provider-specific keys (e.g., OPENAI_API_KEY).
• Run agent: node my_agent.js start
• Documentation: LiveKit Agents Docs

Highlighted Details

• Supports multiple AI service providers via plugins (OpenAI, Deepgram, ElevenLabs, etc.).
• Includes a "playground" web frontend for agent development and testing.
• Offers a new, CPU-optimized phrase endpointing model for better conversational flow.
• Agents are stateful and managed by workers, designed for production resilience.

Maintenance & Community

• The project is in beta, with the Python version recommended for production.
• Community support is available via LiveKit Community Slack.
• Feedback and contributions are welcomed.

Licensing & Compatibility

• Licensed under Apache-2.0 and REUSE-3.2 compliant.
• Permissive license suitable for commercial use and integration into closed-source applications.

Limitations & Caveats

This SDK is in beta, meaning APIs may change and bugs may be present. The Python version of the framework is considered more mature and recommended for production use.
