Rerankers

Cross-Encoder MS MARCO (MiniLM, TinyBERT, mMARCO)

The most downloaded open rerankers: a tiny model reads a question-passage pair and scores how well they match. The multilingual mMARCO version covers Russian.

The last open version came out in Jun 2022. The family has not been updated for a long time: the model still works, but do not expect fixes or new sizes.
