FinanceMTEB/Fin-e5-tokenizer

FinE5: Finance-Adapted Text Embedding Model This financial embedding model is fine-tuned on a synthesized finance corpus, following the training pipeline of e5-mistral-7b-instruct (Wang et al., 2023). It ranks top on FinMTEB (Feb 16, 2025), with no overlap between training data and benchmark test set.

The training data and pipeline are detailed in the paper.

This is the tokenizer of FinE5.
