 "Sarashina-Embedding-v2-1B" is a Japanese text embedding model, based on the Japanese LLM "[Sarashina2.2-1B](https://huggingface.co/sbintuitions/sarashina2.2-1b)".
-We trained this model with multi-stage contrastive learning. We achieved the state-of-the-art average score across 28 datasets in  [JMTEB](https://huggingface.co/datasets/sbintuitions/JMTEB) (Japanese Massive Text Embedding Benchmark).(Benchmarked on July 28,2025.)

 This model maps sentences & paragraphs to a 1792-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and other applications.

 ### How to add instructions and prefixes
 
-For both the query and document sides, use different prefix formats. On the query side, add the prefix `task:` followed by instructions. (*Only for STS tasks: The document side should also use the same format of instruction and prefix as the query side.)
