Overview
Research summary
Sentence Transformers provides Python interfaces for producing embeddings and scoring the relevance of query-document pairs. Developers can load compatible pretrained checkpoints, encode data for semantic retrieval, evaluate retrieval behavior, or fine-tune models on their own examples. The library includes dense embedding models, sparse encoders, and cross-encoder rerankers, with supported modalities depending on the selected checkpoint.
It is maintained under Hugging Face after originating at the UKP Lab. The library is Apache-2.0 software, while pretrained checkpoints have independent model licenses that must be checked separately before deployment.
