Defying Gravity: The Evolution of Agent-First Development

In this transcript, Kevin Hou from Google DeepMind introduces Anti-gravity, a pioneering agent-first development platform designed to redefine software engineering workflows. The system integrates three primary interfaces: a specialized code editor, an agent-controlled browser for live testing, and a central agent manager for high-level orchestration. A core innovation is the use of artifacts, which are dynamic visual representations like architecture diagrams or screen recordings that allow developers to supervise complex tasks without reading raw code. By leveraging the multimodal capabilities of Gemini 3, the tool enables users to provide feedback across different formats, including highlighting images and commenting on mockups. This product is the result of a tight research-and-development flywheel at DeepMind, aiming to transition developers from manual coding to managing multiple autonomous sub-agents in parallel.
