Jules November 19, 2025 Changelog

Jules is an AI assistant that helps you write and fix code, and this update swaps in a brand-new, smarter AI model called Gemini 3 Pro. This release matters most to developers who use Jules to build apps, because it makes the AI much more independent and reliable when doing actual work. Right now, it's rolling out to Google AI Ultra subscribers, and it will reach Pro users in a few days.

What's new

• Visual Verification: Jules can now "see" the web apps it builds. Using Gemini 3 Pro's new visual skills, Jules can render (load up) the app and actually look at the results to make sure everything appears correctly on the screen.
• Agentic Memories: Jules now uses its memory of your past conversations much better. It can pick up on your specific coding style and the unique details of your project, so it gives you code that fits what you actually want over time.

Improvements

• Coherent Planning: When you give Jules a big task that requires multiple steps, it doesn't get lost between steps anymore. It moves from one phase to the next much more naturally, meaning you don't have to constantly manage it or correct its course.
• Smarter Overall: The new model is better at logical thinking (reasoning), follows your exact instructions more closely, and is just generally more reliable for your day-to-day coding work.

Fixes

No fixes were specifically mentioned in this update, as the focus is entirely on introducing the new Gemini 3 Pro model.
