Generative UI Global Hackathon: Agentic Interfaces
A synchronized, heads-down build session happening across AI Tinkerers cities worldwide - one global challenge, one submission platform, one day.
About
For three years, every “AI-powered” app has been a chatbot wearing a trench coat. Text in, text out. On May 9, we take the training wheels off. This is a build day for Generative UI - agents that don’t just return text, they render complete, interactive interfaces on the fly. Forms, dashboards, approval flows, entire applications - generated natively from agent output. Presented by AI Tinkerers, Google DeepMind, and CopilotKit. Enter The UnHackathon No pitches No panels No chat-wrappers Come build for six focused hours with engineers tackling the same frontier problem at the same moment around the world. Short global kickoff. Heads down. Show and tell at the end. Working code over slides. Format 12:00 PM - Doors open (check-in, food, team-up) 12:30 PM - Global kickoff video: generative UI, the stack, the tracks 1:00 PM - Build. Teams form, starter kits and credits distributed 5:00 PM - Show and tell. 2-3 minute demos. Working code only. 6:00 PM - Submissions close. Projects submitted to the hackathon platform. The Challenge: Beyond the Chatbox We are looking for functional prototypes that push the boundaries of how users interact with AI. Participants will compete to build systems that demonstrate: Dynamic Component Generation: UI that adapts its structure and state based on the underlying model’s reasoning. Agentic Feedback Loops: Interfaces that allow users to steer autonomous agents through interactive, real-time visual elements. Latency-Optimized Rendering: Utilizing techniques like KV cache optimization or local execution (via Gemma 4 or Muse Spark) to ensure fluid, zero-lag user experiences. Tool-Enabled Interfaces: UI that doesn’t just display data but provides the interactive hooks for agents to execute cross-app workflows. Build with the protocols and frameworks defining generative UI in 2026: A2UI (Google) - Open protocol for agents to send interactive components. Apache 2.0. AG-UI (CopilotKit) - Protocol for connecting AI agents to frontend UIs. CopilotKit - Framework for embedding AI copilots into React apps. MCP Apps - Model Context Protocol applications rendered as interactive UI. Food and drinks will be provided. Registration & Contribution This is not for generative UI enthusiasts. This is for tinkerers. We are screening for engineers who write code and will ship something by 6 PM. Space is limited. Not for everyone. For the ones who build.
