Milvus

Milvus is an open-source vector database built for massive-scale AI similarity search, capable of managing billions of embedding vectors with millisecond query performance. It provides GPU acceleration, multiple index types for different accuracy-speed tradeoffs, and support for various embedding modalities including text, images, and video — making it the go-to infrastructure for enterprise AI applications requiring high-throughput vector search. AI teams at companies including Salesforce, Walmart, and Nvidia use Milvus as the foundation for recommendation systems, semantic search, multimodal AI, and RAG applications that operate at production scale.
