Thor from Google DeepMind walks through how to set up the Gemini Live API with Twilio and deploy it to Google Cloud Run, so anyone can call your Gemini voice agent from a regular phone number. Inbound and outbound calls, real-time audio streaming, and the same agent running in the browser and on the phone from a single deployment.
What’s covered: Using the GenAI Python SDK Twilio example from GitHub, building inbound and outbound call handlers with FastAPI and WebSockets, handling audio format conversion between Gemini and Twilio, deploying to Google Cloud Run with Secret Manager, and using Antigravity coding agent skills to accelerate the build.

Grab your Gemini API key at Google AI Studio and your Twilio credentials at twilio.com to get started. Full example and setup instructions linked below.
