Most discussions about the productivity benefits of programming languages are subjective. For Kotlin, however, IDE telemetry gives us objective evidence: When a team switches to Kotlin, their development cycles become quicker and are less hampered by project growth. Over the course of months, the difference adds up, with Kotlin teams' cycles being as much as 15-20% shorter. More details in our blog: blog.jetbrains.com/research/…

The first Mythos-class model Fable 5 by @AnthropicAI is out, and it's already available in JetBrains AI Chat, Claude Agent, Junie, and Air. The model is quite expensive, but in our internal tests it also showed very strong results, so use responsibly!

Code generation is up. But the business impact has… stalled. The productivity paradox is real. And the solution is simple. Spoiler, it’s not another pilot. Join our CPO Kris Kang at #LondonTechWeek as he discusses what really moves mountains for your business.
