LFM2.5-Embedding-350M and LFM2.5-ColBERT-350M Released

LFM2.5-Embedding-350M is a dense bi-encoder that provides fast multilingual retrieval with one vector per document, achieving best-in-class accuracy for its size and inference speed comparable to smaller models. LFM2.5-ColBERT-350M is a late interaction retriever with best-in-class multilingual accuracy, enabling cross-lingual retrieval by storing one vector per token and supporting retrieval in multiple languages with high precision. Both models are designed as drop-in replacements for existing RAG pipelines.
