Gemini Spark Hits US Public Beta for Google AI Ultra Subscribers — 24/7 Background Agent on Antigravity Harness Drives Gmail, Docs, Calendar, Maps, and MCP-Connected Canva, OpenTable, and Instacart
Google starts rolling Gemini Spark out as a public beta to US Google AI Ultra subscribers. The 24/7 cloud agent — first shown at I/O 2026 — now runs in the background across Workspace and partner apps, manages up to 15 tasks at once, and asks for user approval on sensitive actions.

Google's I/O-announced personal agent goes from trusted-tester preview to a public beta inside the $100/month AI Ultra plan in the United States.

What is it?
Gemini Spark is Google's always-on personal agent. After Google announced it at I/O 2026 on May 19, 9to5Google and Thurrott independently report that Spark is now reaching all US Google AI Ultra subscribers in beta. The product sits in a new 'Spark' tab in the Gemini app on web, Android, and iOS, and is built on Google's Antigravity agentic environment.
How does it work?
Spark wraps the Gemini models (Google has paired the rollout with Gemini 3.5 Flash) inside an agent harness that runs in Google's cloud, so tasks keep executing even when the phone is locked or the laptop is closed. Users describe high-level goals as Tasks, attach Schedules for cadence, and teach reusable Skills in natural language. Spark hooks into Google Workspace (Gmail, Calendar, Drive, Docs, Sheets, Slides, Maps, YouTube), invokes a remote browser and remote computer for code execution, and reaches third-party apps like Canva, OpenTable, and Instacart through MCP. It asks for user confirmation on actions like sending mail or completing transactions.
Why does it matter?
Spark is the first widely available, consumer-grade always-on agent from a frontier lab — measured in monthly Gemini app users, the addressable surface is the largest of any agentic assistant shipped to date. It also forces the rest of the agentic-assistant pack (ChatGPT Agent, Claude Cowork, Microsoft Copilot Actions) to compete on real-world task completion rather than demo videos.
Who is it for?
