KotlinLLM, a research prototype for delegating runtime logic to a large language model (LLM) from Kotlin code, is now going open source and public, JetBrains announced.
Revealed July 28, KotlinLLM is an IntelliJ IDEA plugin prototype for experimenting with LLM-driven “Smart macros” in Kotlin, enabling code generation, runtime updates, and hot-reloading. In software engineering, LLMs are commonly used during development for code completion, code generation, and program comprehension, JetBrains noted, but using an LLM at run time of a compiled application is much less common. The existing options for doing this have the following trade-offs, according to JetBrains:
Direct runtime delegation is slow, non-deterministic, and costly, and makes the application depend on an LLM service at run time.
External agent workflows keep the generated logic outside the codebase, where it is harder to review, test, and ship.
Most prior work (byLLM, nightjar, Healer) targets interpreted languages like Python, not a compiled, statically typed language like Kotlin.
