LanceDB is an AI-native multimodal lakehouse that unifies vector, full-text, and hybrid search with SQL filters for production-ready retrieval.

LanceDB is an AI-native multimodal lakehouse designed to handle complex AI data workloads. It provides capabilities for curation, feature engineering, search & retrieval, and training directly from curated data. The platform supports various data types including text, images, audio, and video, making it suitable for diverse AI applications. The core of LanceDB is the Lance file format, which offers efficient storage and retrieval for multimodal data. It features distributed indexing, distributed query execution, HNSW centroid routing, and fast RaBitQ rotation to scale vector search to billions of vectors. The platform also includes JSONB storage, scalar indexing, data evolution, and full-text search capabilities. LanceDB aims to simplify the AI/ML stack by providing a unified platform for data infrastructure, enabling faster model development and improved productivity for ML engineers and data scientists.
