To our knowledge, It is one of the best publicly opened Korean retrieval models.

πŸ€— transformers model that has been pushed on the Hub. - **Developed by:** [NLP&AI Lab](http://nlp.korea.ac.kr/) - **Language(s) (NLP):** Korean, English - **License:** MIT - **Finetuned from model:** [BAAI/bge-m3](https://huggingface.co./BAAI/bge-m3) ## Example code ### Install Dependencies First install the Sentence Transformers library: ```bash pip install -U sentence-transformers ``` ### Python code Then you can load this model and run inference. ```python from sentence_transformers import SentenceTransformer # Download from the πŸ€— Hub model = SentenceTransformer("nlpai-lab/KURE-v1") # Run inference sentences = [ 'ν—Œλ²•κ³Ό 법원쑰직법은 μ–΄λ–€ 방식을 톡해 기본ꢌ 보μž₯ λ“±μ˜ λ‹€μ–‘ν•œ 법적 λͺ¨μƒ‰μ„ κ°€λŠ₯ν•˜κ²Œ ν–ˆμ–΄', '4. μ‹œμ‚¬μ κ³Ό κ°œμ„ λ°©ν–₯ μ•žμ„œ
