Introducing Gemini 3 in Jules: Next-Level AI for Developers

Google has revealed Gemini 3, its most advanced AI model designed to turn ideas into reality. The new Gemini 3 Pro is now available in Jules, Google’s autonomous coding assistant, initially rolling out to Google AI Ultra subscribers and soon to Pro plan users.

Gemini 3 outperforms its predecessor, Gemini 2.5 Pro, by excelling in complex, multi-step tasks and agentive workflows. It offers enhanced reasoning capabilities, better alignment with user intent, and increased reliability for daily coding activities. Tasks that require multiple steps now progress more smoothly, keeping plans coherent and context intact with less user effort.

Jules has been expanded to work across various platforms, such as terminal tools, the Gemini CLI extension, and the Jules API. All these interfaces now share a unified view of projects, allowing seamless transitions without losing progress. The aim is to reduce the cognitive load on developers, giving them more space to focus on creative problem-solving rather than managing tools.

Recent updates improve Jules’ predictability and transparency. The CLI supports parallel operations, works better on Windows, and features a diff viewer for safer change confirmation. The Jules API is now stable for custom workflows and automation, with added support for environment variables and session memory enhancements. Reliability has increased with the critic agent, which maintains task focus over longer periods, and Git handling is now safer. Faster response times are thanks to improved VM performance.

Upcoming features include directory attachment without GitHub, automatic title updates for project history, CLI shortcuts via the web UI, simplified start modes, and automatic pull request generation for experimental workflows. These improvements aim to make Jules more intuitive and efficient, empowering developers to concentrate on their ideas.

Google encourages users to explore these updates and start using Gemini 3 in Jules at jules.google.com. The ongoing enhancements ensure Jules remains a powerful, always-on tool that adapts to the complexity of real-world software development.
