Researchers have introduced HAKARI-Bench, a lightweight benchmark designed to streamline the evaluation of retrieval architectures and efficiency settings for retrieval-augmented generation and semantic search. This new benchmark reconstructs existing large retrieval suites into smaller datasets, enabling rapid, model-agnostic comparisons across various retrieval families and their efficiency variants like dimensionality reduction and quantization. HAKARI-Bench demonstrates high fidelity, reproducing the rankings of larger benchmarks with a Spearman correlation above 0.97, making it a valuable tool for model selection and regression detection during development.
