 - ✅ [FlashRank](https://github.com/PrithivirajDamodaran/FlashRank) rerankers (ONNX-optimised models, very fast on CPU)

+- ✅ ColBERT-based reranker - not a model initially designed for reranking, but does perform quite strongly in some cases. Implementation is lightweight, based only on transformers.
 - 🟠⭐ RankLLM/RankZephyr: supported by wrapping the [rank-llm library](https://github.com/castorini/rank_llm) library! Support for RankZephyr/RankVicuna is untested, but RankLLM + GPT models fully works!
