Google's Gemini Spark Enables 24‑Hour AI Tasks Without a Running PC

Google announced Gemini Spark at I/O 2026, a personal AI agent designed to act as a 24‑hour digital assistant, executing tasks only with explicit user consent.

Core Features

Gemini Spark runs on the Gemini 3.5 large model and uses Google’s internally built Antigravity framework, which is optimized for long‑running AI tasks, maintaining context continuity and workflow scheduling, avoiding the disconnections and context loss typical of other agents. The framework is described as Google’s version of “Openclaw”.

The key differentiator is the execution environment: the entire Gemini Spark instance runs on a dedicated Google Cloud virtual machine. Users do not need to keep a browser tab open or leave a laptop powered on; tasks sent to Spark continue to run in the cloud even when all personal devices are turned off.

Ecosystem Plan

Currently Gemini Spark can seamlessly integrate with the full suite of Google tools such as Gmail, Google Calendar, and Google Drive. Future support will add third‑party services via the MCP protocol, an industry‑standard interface that lets Spark invoke functions on external platforms (e.g., cross‑platform scheduling, ordering services, handling app notifications) without per‑service adapters.

Unlike many existing AI agents that focus on edge‑side response speed, UI polish, and elaborate multi‑turn dialogue, Gemini Spark addresses the practical pain point of needing a continuously running device for long‑duration tasks by moving execution to Google’s cloud, delivering a reliable always‑on capability.
