We built a Reranker Leaderboard, where we compared top rerankers based on ELO scoring and metrics like nDCG and Recall. You can also find info about their latency. We’ll keep adding new rerankers. Do drop a comment if you want us to test any other reranker.
Each model was tested on the same datasets. Check it out and see which reranker performs best for your RAG models
