LanceDB

LanceDB is an open-source multimodal lakehouse for AI data management, training, and search.

LanceDB is a multimodal lakehouse for AI designed to build better models faster. It serves as one table for the whole AI data loop, offering high-throughput data access for training along with fast, versatile search and retrieval. The platform supports workloads ranging from local development to production scale. Users can train and fine-tune models, load data into PyTorch, browse ready-to-use datasets, and build search applications. The suite includes LanceDB OSS for quickstarts and basic table operations, alongside LanceDB Enterprise.
