Linkup Research has introduced SPARSEUP, an open-source sparse embedding model designed for retrieval tasks. Built on a 149M-parameter ModernBERT backbone, the model is tailored for efficient text search and ranking.
The model achieves a score of 56.4 nDCG@10 on the BEIR-13 benchmark. Linkup Research states this is the best known result for a publicly available sparse encoder in the under-150M-parameter category.
Sparse embedding models are used in information retrieval to match queries with relevant documents. By keeping the model compact, SPARSEUP aims to deliver strong retrieval performance while remaining accessible for deployment in resource-constrained environments.
Releasing the model as open source allows developers and researchers to integrate it into existing retrieval pipelines. This could benefit search applications and RAG systems that rely on efficient embedding-based retrieval without requiring large computational overhead.
