Image upload September 9, 2025 You can now upload images when creating a task in Jules. Use this to show frontend bugs, design inspiration, UI mocks, or any visual context you want Jules to consider while generating code. For now: Only JPEG and PNG formats are supported.
You can uplaod as many images as you want, as long as the total size is under 5MB.
Image upload is only supported at task creation (we’re working on enabling it for follow-up prompts soon). Note: If your task involves using assets (e.g. logos) directly in code, those must still be committed to your GitHub repo. Read more about Jules image support.
Stacked Diff September 4, 2025 To improve the code review experience, we’ve introduced a new stacked layout for the diff viewer. This change displays diffs for multiple files vertically on a single screen. The stacked view makes it easier to see related changes across your codebase at a glance, providing better context and speeding up your review process. Changes: The diff viewer now stacks file changes vertically by default
You can also toggle back to the previous tabbed diff viewer
Improved Jules Critic September 3, 2025 We’ve shipped significant improvements to the Jules critic agent, making its feedback more insightful and reliable.

Clicking on a sample prompt will add the text of the prompt to the input box.
Render images in the diff viewer August 22, 2025 Jules now intelligently renders images within the diff viewer, providing an immediate visual context for your modifications. This means: Instant Visual Feedback: When Jules generates images (like charts, diagrams, or web UI screenshots), you’ll see the actual image in the diff, not just its code representation.
Streamlined Workflow: No need to switch between tools or download files to see the results. Jules keeps everything in one place. Try it out! Ask Jules to render an output, like a graph based on data, and commit it to your repository. You’ll be able to see the generated image seamlessly within your diff viewer.
Export at any time August 15, 2025 You’re now in full control of when your code gets to GitHub. No need to wait for a task to finish or ask Jules to do it for you. At any point during a task, just click the GitHub icon in the top right to publish the current work-in-progress as a new branch or open a pull request. This gives you more flexibility and control to review, test, or take over whenever you’re ready.
Increasing the VM Size to 20GB August 15, 2025 We heard your feedback about running into disk space limits on larger projects. To address this, we’ve significantly increased the available disk space in the Jules VM to 20GB. This provides more room for large dependencies, build artifacts, and complex repositories, reducing disk-related failures so Jules can tackle bigger tasks. Happy Julesing!
Critic Agent August 8, 2025 Great developers don’t just write code, they question it. And now, so does Jules. We’ve built the Jules critic agent to ensure that every line of code isn’t just functional, but robust, secure, and efficient. It acts as an internal peer reviewer, challenging every proposed change to elevate the quality of the final output. Some high level notes: Critic-augmented generation: The Jules critic is integrated directly into the generation process. Every proposed change undergoes adversarial review before completion.
Improved code quality: The critic flags subtle bugs, missed edge cases, and inefficient code. Jules then uses this feedback to improve the patch in real-time.
A new kind of review: The critic is not just another linter or test. It understands the intent and context behind code, similar to a human peer reviewer.
Built on research: This feature draws on research into multi-step, tool interactive critiquing and actor-critic reinforcement learning, where an “actor” generates and a “critic” evaluates.
Interactive Plan August 8, 2025 Meet Interactive Plan. Instead of jumping straight to the solution, Jules will now read your codebase, ask clarifying questions, and work with you to refine the plan. This collaborative approach gives you more control and ensures you’re on the same page, leading to higher-quality code and a more reliable solution. In summary: Trigger the interactive plan from the dropdown when you start a task
Jules will start a brainstorm with you and ask clarifying questions
