LEMUR reduces multi-vector retrieval for late interaction models such as ColBERT into regular single-vector retrieval.

LEMUR helps developers who are building search and retrieval systems to make them much faster. It takes collections of document embeddings and query embeddings, and outputs a ranked list of relevant documents. This is useful for anyone working with large text datasets who needs to quickly find the most relevant documents for a given query.

Use this if you are a developer building a search system that uses late interaction models like ColBERT and need to significantly speed up your retrieval process.

Not ideal if you do not have an AVX-512 compatible CPU or are not comfortable working with Python development tools.
