Google Antigravity Runs on Gemini 3 for Next-Gen Coding

Google Antigravity uses Gemini 3 Pro to power AI agents that plan, build, and test code with full transparency, giving developers a smarter workflow.

Think AI coding assistants have hit their limit? Google Antigravity just proved otherwise, and the shift is impossible to miss. It’s not just another AI helper. It works in a way that feels new and a little mind-blowing, almost like you’re watching the future of coding unfold right in front of you.

And for anyone searching for the Google antigravity download just to see what the hype is about, the excitement makes sense.

Here’s the thing: this isn’t about smart autocomplete anymore. It’s about AI agents acting like tiny developers who understand the goal, plan the steps, and complete tasks with full transparency.

What Is Google Antigravity?

Google built Antigravity as a full AI-driven coding environment where agents can move through the entire workflow without hiding anything. They can run commands in the editor, check results in the browser, work directly through the terminal, and record every step they take.

With this setup, Google Antigravity produces detailed artifacts like task outlines, implementation notes, screenshots, and even browser recordings that show the agent’s actions in real time. Instead of guessing how a solution came together, developers can watch the whole process unfold with complete transparency.

Let’s break it down with the two main views inside the Antigravity IDE:

Editor View

Basically VS Code‘s layout if you’re familiar with it, plus this agent panel where the AI actively writes, edits, and runs tests instantly.

Manager View

It’s kind of like having your own mission control center. Spin up a bunch of agents, set them loose in different workspaces, and just watch them tackle everything at once. It offers a glimpse of what multi-agent development could become.

The way these two views work together makes Antigravity feel less like a tool and more like a shared development ecosystem where humans and agents build side by side.

Why Gemini 3 Pro Powers Antigravity?

At the core of the system is Gemini 3 Pro, Google’s newest model built for reasoning and long-step problem solving. While smaller models focus on single responses, Gemini 3 Pro can break tasks into structured steps, plan execution, and verify the results. Google even introduced a client-side bash tool that allows the model to propose and safely run shell commands.

One of Google’s demos showed an agent building a simple flight tracker. It generated the idea, wrote the app, executed it, and validated the final interface using browser recordings. Watching an AI handle an entire workflow inside an IDE makes it clear that Antigravity is more than another coding assistant.

Expanded Model Options for Developers

Even though Gemini 3 Pro is the main engine, Antigravity supports other models, including Claude Sonnet 4.5 and GPT-OSS open-source options. Developers aren’t locked into a single AI ecosystem, which makes the platform feel more flexible than many AI-first tools available today.

Antigravity’s public preview runs on Windows, macOS, and Linux. And while Gemini 3 Pro has usage limits, Google describes them as fairly generous, especially for experimentation and early development.

Why Does This Matters for Developers?

If you write software today, you already know how much time disappears into repetitive tasks, debugging loops, and documentation. Antigravity aims to lighten that entire load. Agents produce explainable outputs, accept feedback through comments, and learn over time by remembering what worked in previous sessions.

It’s a meaningful step toward AI that collaborates instead of simply suggesting.

Final Thoughts

Google Antigravity and Gemini 3 Pro feel like the start of a new wave in software development. These AI coding assistants verify their own output, grasp your project goals, and seamlessly manage multiple environments.

This represents a fundamental change in software development workflows. For anyone interested in the evolution of programming tools, it’s an experiment that deserves attention and hands-on exploration.
