Google has open-sourced A2UI – a UI language for AI agents

It allows agents generate user interfaces instead of only text.

→ Agents send a JSON description of UI components, and the client app renders them with its own trusted widgets.

The benefits:

  • declarative UI format (JSON, not code)
  • safe: only approved components can be rendered
  • framework-agnostic (web, Flutter, etc.)
  • supports incremental UI updates

So agents can "speak UI," while the application keeps control over security and implementation https://github.com/google/A2UI https://blossom.primal.net/43ebf6180d0354cb5ca3635feb43161b1d47514748a59c758e0e1b3dd627bed3.jpg
