multilingual-e5-base

multilingual-e5-base is a multilingual text embedding model from Microsoft using an XLM-RoBERTa backbone, trained with E5's text-pair ranking objective across 94 languages. It produces 768-dimensional sentence embeddings for semantic search, clustering, and cross-lingual retrieval. The base variant balances embedding quality and inference cost between the small and large tiers.
