Most Artificial Intelligences live on screens. We decided to take AI to the streets. I'm very proud to share the project we developed for Google's Gemini Live Agent Challenge: First Runner. First Runner isn't just another running app. We transformed the entire city into a territorial conquest board, guided by a "Cyberpunk Coach" (The Oracle), natively powered by Gemini 2.5 Flash. Why is this different from what you've seen before? The Oracle speaks to you in real time (Native Audio, without relying on slow TTS). The model silently receives your telemetry: pace, distance, current territory. Each street is a territory to be conquered. Opponents can invade your zones while you run. The AI's responses are tactically relevant: "You are 100 meters away from dominating this area, keep your pace!" Our Technical Stack: We built the bridge between the street and the cloud using: • Flutter/Dart for raw (16kHz PCM) microphone audio capture. • WebSocket server running frenetically on Google Cloud Run. • Background JSON context injection without breaking the Gemini Live audio pipe. • Firestore for global state synchronization and territory control. Spending the last few weeks building the "Real-World Spatial UI" frontier with ultra-low latency conversion agents has been challenging and incredible.
The app is already in production on the Google Play Store and our entire architecture is documented!
