A2UI 1.0 is out under Apache 2.0! 🎨

From @developers.google.com, agents stream declarative UI rendered natively by @react.dev, @angular.dev, @flutter.dev, Lit & SwiftUI—plus MCP Apps.

What would you build first with your design system?
goo.gle/a2ui-1-0
Google Open Source social card 1 of 4 for A2UI 1.0. Headline reads: 'A2UI 1.0: Native Agent UI — Agents stream declarative JSON; clients render native components.' Center panel displays the official A2UI 1.0 architecture diagram showing an A2UI v1.0 message payload (Card, BarChart, ChoicePicker, Button) connecting to synchronized desktop web, Android, and iOS interfaces. Footer reads 'a2ui.org • goo.gle/a2ui-1-0' and bottom strip invites viewers to swipe for token savings, renderers, SDKs, and links. Google Open Source social card 2 of 4 for A2UI 1.0 titled 'One View, Native Everywhere.' Center panel features the A2UI multi-screen diagram demonstrating one declarative dinner-planning interface rendered natively on both smartphone and laptop screens, listing 1.0 renderers (React, Angular, Lit, Flutter, SwiftUI) plus community renderers. Green callout bar below notes that A2UI Express cuts output tokens 2.7x to 3.1x (-45.4% prompt tokens) and supports custom catalogs and MCP Apps. Google Open Source social card 3 of 4 for A2UI 1.0 titled 'Ship With Your Design System.' Top banner displays the A2UI quickstart terminal graphic alongside 'npx skills add a2ui-project/a2ui' for Python, TypeScript, and Dart SDKs, noting adoption with Alation, Atlassian, Bloomberg, and ByteDance. Below, a 2x2 grid highlights: Catalog Allowlists (Security: declarative JSON, zero raw JS), On-Device Ready (Local AI: Soverius AI fine-tuned Gemma 4), MCP Apps and AG-UI (Interop: bidirectional tool RPCs), and Apache 2.0 (a2ui.org). Google Open Source social card 4 of 4 for Bluesky (@opensource.google) titled 'Read the Release, Join the Community.' Left panel lists verified ecosystem handles: @developers.google.com, @flutter.dev, @angular.dev, and @react.dev. Right panel invites replies: 'What would you build first with your design system? a2ui.org • Apache 2.0.' Bottom banner prompts readers: 'Read the A2UI 1.0 Launch Post — Link in post above: goo.gle/a2ui-1-0.'

A2UI reached version 1! 🚀

This protocol lets agents define a component tree, and frameworks like #Angular or #React render it.

Our video explains how A2UI works and shows it in action:

Google releases A2UI 1.0, so your AI agent can answer with a real form, chart or booking picker instead of a wall of text

The agent sends JSON for the screen, and your app renders it using approved native components to ensure brand consistency

Why A2UI Express? Because models can struggle to produce valid JSON for A2UI.

A2UI Express allows the model to generate compact, Python-like code instead. This reduces the amount of output and can improve its reliability.

My already optimized Gemma 4 example now generates dynamic dashboards 35% faster.

By combining A2UI Macros with A2UI Express.

The model expresses an UI surface in a compact coarse-grained form + code expands it into standard A2UI.

Google has released A2UI 1.0, and guess who got a mention in the official announcement? @soverius-ai.bsky.social!

We fine-tuned the Gemma 4 E2B and E4B models for A2UI Express. Models of this size can even run in your browser.

Nice! I’m currently working on the 'a2ui' chapter from @manfredsteyer.bsky.social’s book 'Agentic UI with Angular', so this will tie in perfectly. 😊

Google made A2UI 1.0 stable, adding function calls in both directions. Agents describe native interfaces using registered components; runtime checks decide which side can call each function.
