Pinecone

Pinecone is a fully managed vector database designed for building and deploying AI applications that rely on high-dimensional embeddings. It stores, indexes, and retrieves vector representations of data such as text, images, audio, or user behavior, enabling efficient similarity search and retrieval-augmented generation (RAG) at scale. The platform handles indexing, sharding, replication, and low-latency querying so teams can focus on application logic rather than infrastructure.

Key capabilities include approximate and exact nearest neighbor search, hybrid search combining keyword and vector relevance, and support for billions of vectors with millisecond-level query performance. Pinecone provides APIs and SDKs for common languages, integrates with popular embedding models and LLM frameworks, and offers tools for namespace management, metadata filtering, and result ranking. It also supports upserts, deletions, and versioning of vector data to keep AI applications in sync with changing information.
