Google Gemini 2.0 support

Introducing support for the new Gemini 2.0 model. Here's an example voice agent running Google STT, TTS, and Gemini 2.0 Flash: code

In-house phrase endpointing model

We’ve trained a new, open weights phrase endpointing model that significantly improves end-of-turn detection and conversational flow between voice agents and users by reducing agent interruptions. Optimized to run on CPUs, it’s available via livekit-plugins-turn-detector package.

What is Agents?

The Agents framework enables you to build AI-driven server programs that can see, hear, and speak in realtime. It offers a fully open-source platform for creating realtime, agentic applications.

Features

• Flexible integrations: A comprehensive ecosystem to mix and match the right models for each use case.
• AI voice agents: VoicePipelineAgent and MultimodalAgent help orchestrate the conversation flow using LLMs and other AI models.
• Integrated job scheduling: Built-in task scheduling and distribution with dispatch APIs to connect end users to agents.
• Realtime media transport: Stream audio, video, and data over WebRTC and SIP with client SDKs for most platforms.
• Telephony integration: Works seamlessly with LiveKit's telephony stack, allowing your agent to make calls to or receive calls from phones.
• Exchange data with clients: Use RPCs and other Data APIs to seamlessly exchange data with clients.
• Open-source: Fully open-source, allowing you to run the entire stack on your own servers, including LiveKit server, one of the most widely used WebRTC media servers.

Installation

To install the core Agents library:

pip install livekit-agents

Integrations

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:

pip install livekit-plugins-openai

Realtime API

We've partnered 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.
