SlideOn charts near the quality-cost Pareto frontier for sub-2B sparse retrieval
tomaarsen · x · 2026-10-20
On BEIR-15, SlideOn scores 56.68 nDCG@10—beating its dense starting point DenseOn (56.20) and nearing LateOn (57.22)—while using sparse dot-product scoring. The quality-vs-retrieval-FLOPS chart places SlideOn (d=512) on the Pareto frontier for <2B models, well above SPARSEUP, SPLADE-v3, and OpenSearch sparse baselines; only LACONIC-1B sits in a higher-quality region.
