Using LiveKit Agents

LiveKit Agents is an open-source framework for building voice AI agents. The OpenRouter plugin allows you to access 500+ AI models from multiple providers through a unified API, with automatic fallback support and intelligent routing.

Installation

Install the OpenAI plugin to add OpenRouter support:

$
uv add "livekit-agents[openai]~=1.2"

Authentication

The OpenRouter plugin requires an OpenRouter API key. Set OPENROUTER_API_KEY in your .env file.

Basic Usage

Create an OpenRouter LLM using the with_openrouter method:

1
from livekit.plugins import openai
2
3
session = AgentSession(
4
    llm=openai.LLM.with_openrouter(model="anthropic/claude-sonnet-4.5"),
5
    # ... tts, stt, vad, turn_detection, etc.
6
)

Advanced Features

Fallback Models

Configure multiple fallback models to use if the primary model is unavailable:

1
from livekit.plugins import openai
2
3
llm = openai.LLM.with_openrouter(
4
    model="openai/gpt-4o",
5
    fallback_models=[
6
        "anthropic/claude-sonnet-4",
7
        "openai/gpt-5-mini",
8
    ],
9
)

Provider Routing

Control which providers are used for model inference:

1
from livekit.plugins import openai

llm = openai.LLM.with_openrouter(

    model="deepseek/deepseek-chat-v3.1",
5
    provider={
6
        "order": ["novita/fp8", "gmicloud/fp8", "google-vertex"],
7
        "allow_fallbacks": True,
8
        "sort": "latency",
