Google AI ecosystem support

Google AI provides some of the most powerful AI models and services today, which integrate into LiveKit Agents in the following ways:

• Gemini: A family of general purpose high-performance LLMs.
• Google Cloud STT and TTS: Affordable, production-grade models for transcription and speech synthesis.
• Gemini Live API: A speech-to-speech realtime model with live video input.

LiveKit Agents supports Google AI through the Gemini API and Vertex AI.

Getting started

Use the Voice AI quickstart to build a voice AI app with Gemini. Select an STT-LLM-TTS pipeline model type and add the following components to build on Gemini.

Install the Google plugin:

pip install "livekit-agents[google]~=1.0"

Add your Google API key to your .env. file:

GOOGLE_API_KEY=<your-google-api-key>

Use the Google LLM component to initialize your AgentSession:

from livekit.plugins import google

# ...

# in your entrypoint function
session = AgentSession(
    llm=google.LLM(
        model="gemini-2.0-flash",
    ),
    # ... stt, tts,vad, turn_detection, etc.
)
