Let’s take a look at this week’s fresh additions! If you missed our previous overviews of the newly added features, no worries – just head over to the IntelliJ IDEA 2025.1 EAP section on our blog to catch up.

JetBrains AI Assistant 

Support for more cutting-edge LLMs

JetBrains AI Assistant is leveling up! We’ve added support for Claude 3.5 Sonnet and Claude 3.5 Haiku, now provisioned in Amazon Bedrock. This means sharper responses, faster insights, and an even smoother experience.

We’re also expanding the lineup of LLMs used by AI Assistant to include OpenAI’s o1, o1-mini, and o3-mini, providing more versatility and speed. Whether you need deep analysis or quick, yet well-considered insight, JetBrains AI Assistant is ready to power your ideas like never before!

Debugger

Pause and resume evaluation of watches

You can now pause and resume the evaluation of watches to control possible side effects of a watch computation. 

Simply right-click a watch during evaluation and select Pause Watch. While paused, the watch won’t evaluate and report errors. To resume the evaluation process, click Resume Watch in the context menu.

This is especially useful for frameworks like Spring and Hibernate, where watches can trigger unintended behavior, like caching or other side effects. 

User experience 

Improved gutter for VCS

We’ve introduced a cleaner, more intuitive way to track your edits via VCS. The change marker now appears on the right-hand side of the gutter area, closer to the modified lines. This makes changes more visible and easier to interact with.
