walkie-talkie

Google I/O Hackathon

A **dual-model voice agent**: press to talk, the front-end handles the conversation, the background does the work. 1. **Front-end model** handles real-time voice interaction (listen, speak, pivot mid-conversation) 2. **Background model** handles tool execution in a persistent sandbox (files, charts, generative UI) LLM products today split into two camps: **full-duplex** (live voice) and **turn-based** (chat + tools). One is great at talking, the other is great at doing. Nothing sits in between. Walkie-Talkie stitches both: natural real-time voice up front, powerful tool execution in the back. Gemini 3.5 Flash as the background brain keeps latency low.
