## AI overview

This guide explains how to evaluate large language models for coding, focusing on benchmarks relevant to JVM languages such as Java, Kotlin, and Scala. It describes the shift from testing isolated code generation to assessing software-engineering tasks, including HumanEval, MBPP, and SWE-bench.

## Source excerpt

If you're reading this, you're probably already using some LLM for coding. Maybe it's Copilot, maybe Claude Code, maybe Cursor with Gemini enabled (or Cursor's own model). You know the drill. Do you truly expect the announcement "We are worst than competitors?" The problem is that when someone asks, "Which model is best for Java?", [...] The post How to really measure LLMs for JVM Code?
