### AI overview

KotlinLLM is an open-source research prototype and IntelliJ IDEA plugin for Kotlin/JVM projects. It introduces Smart macros whose generated Kotlin source evolves from runtime scenarios, allowing applications to delegate selected logic to an LLM without calling the model on every request or relying on a separate runtime agent.

### Source excerpt

TL;DR KotlinLLM is now public. It's a research prototype for delegating runtime logic to an LLM from Kotlin code. Instead of calling an LLM on every request or running a separate agent, you can write an explicit Kotlin call. Its body is generated Kotlin source code, and that code is updated as your application hits [...]
