- What happened
- Sentence Transformers v6.0 adds MultiVectorEncoder for ColBERT-style late interaction retrieval, supporting PyLate and Stanford-NLP checkpoints.
- Why it matters
- Matters for engineers building semantic search and RAG systems who need better retrieval on rare entities, exact matches, or multi-requirement queries.
- Watch out
- Multi-vector models use 42x more storage than dense embeddings per passage, though compression techniques can reduce this to comparable levels.
