Pinecone

Pinecone is a fully managed vector database built for AI applications, making it easy to add semantic search, recommendation engines, and other vector-based features to applications. It specializes in storing and querying high-dimensional vectors generated by machine learning models. Key features include fully managed infrastructure with automatic scaling, low-latency vector search with millisecond response times, hybrid search combining vector and metadata filtering, namespace support for multi-tenancy, real-time index updates, sparse-dense vector support, integration with LLM frameworks like LangChain, high availability and reliability, and simple API for CRUD operations. Pinecone is used by companies building RAG applications, recommendation systems, semantic search, image similarity, and anomaly detection systems.
