Design a High-Precision Retrieve-and-Rerank Pipeline with ZeroEntropy Zerank-2 Reranker
A tutorial demonstrates how to implement a high-precision retrieve-and-rerank pipeline using the zeroentropy/zerank-2-reranker model. This model, based on Qwen3, functions as a cross-encoder to improve search result quality. The process involves an initial retrieval step with a fast bi-encoder, followed by a reranking stage using zerank-2 to refine the precision of the results. The tutorial showcases its application across finance, legal, and code domains, evaluating performance with NDCG@10. AI
