Google’s research arms — Google Research and Google DeepMind — published MUVERA (Multi-Vector Retrieval via Fixed Dimensional Encodings), which reduces multi-vector Late Interaction search to single-vector MIPS. The method was announced on the Google Research blog and has since been implemented in Weaviate Vector DB, Qdrant Vector DB (via FastEmbed) and an OpenSearch sample.
