Overview
multilingual-e5-base from intfloat supports 100 languages (initialized from xlm-roberta-base) in a single model, enabling cross-lingual semantic search where queries and documents can be in different languages. It produces 768-dimensional mean-pooled vectors from inputs up to 512 tokens.
Deploy as a SageMaker endpoint in your own AWS account. A single endpoint replaces separate per-language embedding services -- simplified architecture, lower operational overhead, and all documents staying in your VPC.
IMPORTANT: The model requires query and passage prefix instructions. Prepend "query: " to search queries and "passage: " to documents before embedding -- even for non-English texts. Per the model card FAQ: skipping the prefix degrades performance, this is how the model was trained.
Works with pgvector, Amazon OpenSearch, Pinecone, Weaviate, and any vector store accepting 768-dimensional float32 vectors.
Primary use cases: multilingual customer support search, global enterprise document retrieval, cross-lingual product catalog similarity, compliance document search across regions, and any RAG pipeline serving users in multiple languages.
Highlights
- 100-language support in one endpoint -- eliminates per-language model sprawl for global enterprise deployments
- 768-dimensional mean-pooled vectors, 512-token input -- cross-lingual retrieval across query and document language pairs
- Flat $0.08/hr on ml.m5.xlarge -- no token charges, all documents in your VPC, scalable to batch transform for offline ingestion
