Are We Testing Too Much? A Survey of Benchmark Compression for Efficient Evaluation of Large Language Models

Benchmarks are essential for evaluating and improving large language models (LLMs).

Key points

  • Yet many widely used benchmarks are redundant, making evaluation unnecessarily expensive.
  • Benchmark compression lowers this cost by estimating full-benchmark scores and rankings from a partial evaluation.
  • We review 119 papers to explain how methods choose what to evaluate, recover full-benchmark results, and verify their reliability.
  • From this analysis, we develop a taxonomy covering compression within individual benchmarks, across benchmark suites, and during adaptive evaluation, together with work on redundancy and reliability.
