Many development teams are exploring ways to use AI to improve performance, and we're no exception. With AlphaEvolve from @GoogleDeepMind, we've optimized the core indexing logic of JetBrains IDEs, improving real-life benchmarks. jb.gg/zs8y6g

We ran a little experiment: we added support for your JetBrains AI subscription in the Pi coding agent. Nowhere near production ready, but would you actually use this in your terminal? Btw, @wordmandotdev built it with Opus 4.8, now available in JetBrains IDEs.

Zig has strict No LLM / No AI policy. Andrew Kelley, creator of Zig, explains the language's strict No AI policy and why AI-generated PRs become a bottleneck for the team.

Today's highlights from our annual highlights cover growth and trust.

Opus 4.8 is now available in Air

We’re sunsetting JetBrains DataSpell and will no longer be developing it as a standalone IDE. For data science-related workflows, we recommend PyCharm. Learn more about how this affects your license and access to the product here: jb.gg/eq6wah Thanks so much to everyone who used, supported, and believed in DataSpell!

We did it again. Something new for the open-source LLM space is coming to @huggingface soon. Stay tuned.

Developers in 2025: “Another update, again?” Us: “Yeah. Sorry, not sorry!”

Our full conversation with Andrew Kelley, creator of Zig, is out now. No AI policy, leaving GitHub, a $670K nonprofit, and why there's no 1.0 (yet).

Programming courses often happen outside the tools developers use. With the JetBrains Course Creators Program, educators integrate courses into IDEs, making learning hands-on. Participants get free IDE access, partnership opportunities, and media support. jb.gg/ccjp47

There’s still more to improve, and we’d love your feedback – especially if you rely on accessibility features. Learn more in the blog post: blog.jetbrains.com/platform/2026/… P.S. The audio version is available, too!

We’re actively exploring ways to provide richer audio feedback in the IDE – like contextual signals when the caret lands on lines with errors, version control changes, and audio notifications for IDE actions. We want to reduce the need to rely on visual indicators or switch contexts just to understand what changed. More updates are coming soon – stay tuned!

Today is the 15th Global Accessibility Awareness Day. In honor of it, we want to share recent improvements to compatibility with assistive technologies across different platforms, keyboard navigation, and non-visual feedback in JetBrains IDEs. Some of these improvements are already available, and some are coming later this year. Check out the thread for more information. #GAAD
