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). 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. Research in this area has grown...

Zipbench: Low-Cost Framework for Compressing Comprehensive Benchmarks of Large Language Models

This work presents ZipBench, a simple and low-cost BCM with theoretical error and rank-consistency guarantees that reduces the cost of both LLM evaluation and compact benchmark construction, lowering the barrier to broad LLM research for compute-constrained researchers.
