Google Antigravity is an integrated development environment, or IDE, designed with artificial intelligence at its core. Released in November 2025 alongside the Gemini 3 family of models, it's built to change how developers write software. Instead of just getting assistance from AI, developers can delegate entire, complex coding tasks to autonomous AI agents.

The platform is a heavily modified version of the popular Visual Studio Code, so the interface may feel familiar to many developers. The key difference is its agent-first approach. You provide high-level instructions, and the AI agents handle the implementation details.

Antigravity was announced and released in a public preview on the same day in November 2025. It's available free of charge for developers on Microsoft Windows, macOS, and Linux. Google also provides generous rate limits for using the powerful Gemini 3 Pro model within the IDE, making it accessible for individual developers and small teams to start building right away.

While Antigravity is a Google product, it isn't limited to Google's AI models. Its primary agents are powered by the latest Gemini models: Gemini 3 Pro, the advanced Gemini 3 Deep Think, and the speedy Gemini 3 Flash.

Beyond the Gemini family, the platform also supports models from other leading AI labs. Developers can choose to use Anthropic's Claude Sonnet 4.5 and Claude Opus 4.5. It even includes support for an open-source model, GPT-OSS-120B, giving users a range of options to fit their specific needs.

This flexibility allows developers to select the best AI for a particular task, all within a single, integrated environment. It's a platform built for a future where developers orchestrate a team of AI agents rather than writing every line of code themselves.
