Generative UI at Scale with A2UI

AGNTCon + MCPCon North America 2026

Oct 22, 2026 · 10:55–11:20 · America/Los_Angeles

As AI agents become more sophisticated, static front-end applications are increasingly becoming a bottleneck. When agents can reason, plan, and execute complex tasks, collapsing their outputs into a "wall of text" or standard markdown severely limits the user experience. Enter Generative UI (GenUI): an architecture where Large Language Models orchestrate interfaces in real-time or cached, adapting layouts, components, and data visualizations based on user intent and session context. In this session, we will dive deep into A2UI (Agent-to-User Interface), the open-source toolkit shipped by Google that safely bridges the gap between autonomous AI agents and frontend clients. You will learn how A2UI uses a secure, declarative JSONL stream to send UI structures across trust boundaries without ever transmitting vulnerable executable code. You own your own design system, A2UI let's agents drive whatever front end "catalog of components" you want to share. The client is in charge of this contract and the agent adjusts, natively "speaking" UI and dynamically construct interactive, brand-safe experiences across Web, Flutter, Android, and iOS.
