AI Quick Tips 351: Google’s Antigravity Agent

2026 is definitely looking like the year of the AI agent and Google isn’t showing any signs of slowing down…

One of their new-ish offerings is their Antigravity Agent. It is “a general-purpose managed agent on the Gemini API” It is basically an AI tool that can DO things (where chatbots mainly provide information).

Each time you send something to Antigravity Agent (through an API call), it will spin up a secure Linux sandbox environment hosted on Google infrastructure. This environment is where the agent will “live” until your session is over. For now Gemini 3.5 Flash is the only available model.

A few things that you can do with this kind of agent are -

• Plan, build, and execute code
• Install packages, test, build complete applications
• Use tools
• File management - within the sandbox
• Files persist across interactions
• Context compaction - supports long-running sessions without losing context or hitting token limits (in theory)
• Etc.

Some of the tools that are supported are -

• Code Execution
• Google Search
• Filesystem
• Custom Functions
• Remote MCP Server

If you know what these things are then you already know that this covers most of what you can do on a computer.

Antigravity Agent (Preview) is one of the options within Google AI Studio (by the way, it looks like it is paid only):

If you’re more technical (or willing to learn), it is also accessible through the Interactions API
