Overview of Google Antigravity, a new autonomous, agentic development platform marking a significant shift from traditional AI assistant models in software engineering.

This platform is powered by the Gemini 3 model family, specifically leveraging the deep reasoning of Gemini 3 Deep Think and the whole-program awareness provided by a 1-million-token context window.

Antigravity integrates the Editor, Terminal, and Browser into a unified control plane, enabling AI agents to plan complex multi-step tasks, execute code, and visually verify outcomes, thereby raising the developer’s role from code author to agent architect.

The system emphasizes transparency through structured outputs called Artifacts and uses the Model Context Protocol (MCP) to connect agents to external resources like databases and issue trackers, creating a comprehensive and autonomous development workflow.
