Google’s new Gemini Spark AI agent can run your errands while you run your life

Google unveiled Gemini Spark at Google I/O 2026, an AI agent built on Gemini 3.5 and Antigravity.

It runs multi-step tasks on dedicated virtual machines in the background, even after you close your device.

Gemini Spark can use context from Gmail, Drive, and Docs to draft content, update files, and handle follow-ups.

Google will first roll it out to trusted testers and Google AI Ultra subscribers, with broader third-party support planned later.
