Jules

Jules is Google's agentic AI coding assistant: it autonomously writes tests, fixes bugs, and builds features using Gemini 3 Pro.

Jules is Google's autonomous coding agent, a significant step beyond co-pilot tools. Powered by the advanced Gemini 3 Pro model, it operates asynchronously in a secure Google Cloud Virtual Machine (VM), allowing developers to focus on critical work while it handles routine tasks. The agent integrates directly with GitHub, cloning the repository to understand the full codebase context before executing complex, multi-step modifications like feature building or dependency version bumps. This agentic approach has driven over 140,000 public code improvements during its testing phase, streamlining development workflows and enhancing productivity for engineering teams.
