Official Google Developers Blog announcement for A2UI, a portable declarative format for agent-generated interfaces. It explains how remote or local agents can request trusted UI components from a host app instead of emitting arbitrary HTML, making Generative UI safer, cross-platform, and incrementally updateable.
Summary
1. Portable format: Agents describe UI intent in a framework-agnostic JSON structure
2. Security model: Host apps render only from a trusted component catalog
3. Incremental updates: Optimized for progressive, updateable agent responses
4. Cross-platform: Same payload can map to web, Flutter, Angular, and other clients
5. Ecosystem signal: A concrete Google-led standardization effort around Generative UI
