The Google Jules AI coding tool has officially moved out of beta, bringing a wave of powerful new upgrades and improved developer workflows. Built on Gemini 2.5 Pro, Jules now offers smarter planning, faster code execution, and increased free-tier access.
What Is Jules and How Does It Work?
Jules is not just another coding assistant. It focuses on project-scale tasks like planning architecture, adding complex features, and creating branch-safe code. Unlike basic prompt-based helpers, Jules generates a full plan of action before making any changes—similar to a team lead drafting your sprint.
Major Updates in the Official Release
Improved Interface and Reusability
Google has redesigned Jules with a new user-friendly interface. Developers can now reuse previous setups, reducing repetitive training and accelerating coding sessions. This feature ensures that once you align Jules with your project’s logic, you won’t need to start from scratch every time.
Multimodal Testing and Visual Feedback
One of the most exciting features in this release is multimodal support. Jules can test web applications and provide visual representations of the results, allowing developers to iterate more confidently and quickly.
Branch-Based Execution
Worried about AI rewriting your entire codebase? Don’t be. Jules automatically branches your project, so all changes are reviewed and approved like any regular pull request. This safety feature helps avoid accidental codebase damage.
Powered by Gemini 2.5 Pro
There was some early confusion about the AI engine behind Jules. Although Google initially stated Jules uses Gemini 2.5, the company later confirmed it leverages the more advanced Gemini 2.5 Pro for both planning and execution.
This is a big deal. Gemini 2.5 Pro is optimized for deep reasoning, accuracy, and complex task execution. It runs at a higher cost than its standard counterpart, but it delivers far superior performance in real-world developer tests.
Jules vs Gemini CLI GitHub Actions
While Jules handles full project features, the Gemini CLI GitHub Actions tool focuses on smaller tasks like issue tracking and pull request responses. Think of Jules as a project manager and Gemini CLI as an assistant who helps maintain momentum.
Both tools serve developers but in different capacities. Together, they form a comprehensive AI-assisted development stack inside Google’s ecosystem.
More Tasks for Free Users
Expanded Pricing and Usage Limits
The free plan now allows 15 tasks per day, up from 5 during beta. If you craft prompts carefully, this limit should be sufficient for most users. For power users, Google has introduced:
- Pro Plan: $20/month
- Ultra Plan: $250/month
These plans come with increased limits and better support, making them suitable for startups and professional developers.
Real-World Testing Proves Its Value
During testing, Jules successfully added a feature to an open-source project with only two tasks. Even under the free tier, the tool demonstrated strong coding fluency, delivering deployable code without overwhelming the user.
Jules now waits for approval before pushing changes—something the beta version lacked. This allows for full control over implementation without sacrificing speed.
Conclusion: Jules Enters the Coding Arena Fully Armed
The Google Jules AI coding tool has matured into a serious competitor in the developer productivity space. With Gemini 2.5 Pro under the hood, better UI, visual testing, and reusable setups, Jules bridges the gap between planning and execution.
Whether you’re building from scratch or iterating on an existing project, Jules offers a clear, AI-powered advantage. Its thoughtful design and safety-first approach make it one of the best tools available for serious developers in 2025.
