⚡ Want to increase the speed of your iOS builds? Try incremental compilation for Kotlin/Native, by adding this to your Gradle properties:

kotlin.incremental.native=true

This is an experimental feature, and we'd love to hear your feedback.

It can be counter productive as well 🙃

LLMs are differentiating more and more on how to “optimise” the prompts. I.e.

- XML vs yaml vs json
- All caps important instructions were good in gpt4 but bad on gpt5

So fine tuning a prompt for 1 model might detune it for another.

I’ll see if can provide an update on the issue with timeline, and expectations.

Simon Vergauwen @vergauwensimon.bsky.social · 16d

It’s not left to wither, it’s very actively being worked on at the moment.

Developing OSS is sadly very expensive, so we need to carefully consider and balance priorities.

We’re even growing the team working on this. www.jetbrains.com/zh-cn/career...
