Jina-reranker-v3 is a multilingual listwise reranker with 0.6B parameters that introduces "last but not late" interactions. Unlike late interaction models like ColBERT, it applies causal attention to the query and all candidate documents within the same context window, enabling rich interactions before extracting contextual embeddings from the final tokens of each document. This model achieves state-of-the-art BEIR performance with 61.94 nDCG@10, while being significantly smaller than comparable models.
