Multi-LCB: Extending LiveCodeBench to Multiple Programming Languages
Key takeaways
  • Multi-LCB extends LiveCodeBench to support multiple programming languages, not just Python.
  • The benchmark includes competitive programming problems with contamination-aware evaluation.
  • Multi-LCB aims to assess LLM generalization across diverse programming languages used in real-world software engineering.
  • This addresses a key limitation of the original LCB benchmark.
  • The benchmark is designed to provide a more holistic view of LLM coding capabilities.
Full story

LiveCodeBench (LCB) is a widely used benchmark for assessing large language models (LLMs) on code-generation tasks, featuring competitive programming problems with contamination-aware evaluation. However, its current focus on Python limits insights into LLMs' cross-language generalization in real-world software engineering. The newly introduced Multi-LCB benchmark addresses this gap by expanding LCB to include multiple programming languages, providing a more comprehensive evaluation framework for LLMs' coding abilities across diverse ecosystems.
