✨ [NEW] OpenAI Realtime API support

We are partnering with OpenAI on a new MultimodalAgent API in the Agents framework. This class completely wraps OpenAI’s Realtime API, abstracts away the raw wire protocol, and provide an ultra-low latency WebRTC transport between GPT-4o and your users’ devices. This same stack powers Advanced Voice in the ChatGPT app.

• Try the Realtime API in our playground [code]
• Check out our guide to building your first app with this new API

What is Agents?

The Agents framework allows you to build AI-driven server programs that can see, hear, and speak in realtime. Your agent connects with end user devices through a LiveKit session. During that session, your agent can process text, audio, images, or video streaming from a user's device, and have an AI model generate any combination of those same modalities as output, and stream them back to the user.

Features

• Plugins for popular LLMs, transcription and text-to-speech services, and RAG databases
• High-level abstractions for building voice agents or assistants with automatic turn detection, interruption handling, function calling, and transcriptions
• Compatible with LiveKit's telephony stack, allowing your agent to make calls to or receive calls from phones
• Integrated load balancing system that manages pools of agents with edge-based dispatch, monitoring, and transparent failover
• Running your agents is identical across localhost, self-hosted, and LiveKit Cloud environments

Installation

To install the core Agents library:

pip install livekit-agents

Plugins

The framework includes a variety of plugins that make it easy to process streaming input or generate output. For example, there are plugins for converting text-to-speech or running inference with popular LLMs. Here's how you can install a plugin:
