147
+ #### BEIR
148
+
149
+ The KaLM-Reranker-V1 series matches or outperforms strong industrial rerankers from the Qwen, BGE, Jina, and Mxbai families.

152
+ #### MIRACL
153
+ KaLM-Reranker-V1 achieves competitive performance on MIRACL. Within its parameter group, KaLM-Reranker-V1-Large ranks first in 11 of the 18 languages (i.e., ar, bn, de, en, es, fi, fr, ja,
154
+ ko, ru, and sw); six of these languages (i.e., en, es, de, ja, fr, and ru) have reported website usage rates totaling approximately 74.2% among websites with known content languages ([W3Techs, 2026](https://w3techs.com/technologies/overview/content_language)).
