LiveCodeBench Methodology — Methodology

LiveCodeBench evaluates code generation on contamination-free programming problems with rolling cutoffs.

Overview

What it measures: Code generation, self-repair, test-output prediction, and code execution on fresh problems.

How it works

  • Problems sourced continuously from LeetCode, AtCoder, and CodeForces.
  • Rolling time windows allow contamination-free evaluation.
  • Multiple tasks: generation, self-repair, test-output prediction, execution.

Strengths

  • Contamination-resistant
  • Rich multi-task evaluation

Limitations

  • Competitive-programming bias
  • Frequent re-evaluation required

Best use cases

Coding-model contamination control
