Building with Gemini 3 in Jules- Google Developers Blog

This post announces the integration of Gemini 3 Pro into Jules, an autonomous coding agent. Gemini 3 Pro enhances Jules' agentic capabilities, leading to clearer reasoning, stronger intent alignment, and improved reliability for multi-step tasks. Jules is now available on more surfaces (terminal, Gemini CLI extension, API) with a unified project view. Recent improvements to Jules include parallel CLI runs, Windows compatibility, a simpler invocation flow, a diff viewer, a stable API for custom workflows, support for environment variables, improved session memory, more reliable critic agent replanning, safer Git handling, and improved VM performance. Future work includes direct directory attachment, automatic title updates, web UI CLI shortcuts, simplified start modes, and automatic PR creation.
