VECTOR DATABASES: THE COMPLETE GUIDE
Pinecone, ChromaDB, FAISS, Weaviate & Qdrant Compared
By UDDIT, Vector Database Expert & AI Engineer
VECTOR DATABASES FOR AI
Vector databases are essential for modern AI applications including RAG systems, semantic search, and recommendation engines. They store embeddings for lightning-fast similarity search across millions of documents. I have hands-on production experience with all major vector databases.
✎ EDITOR'S NOTE
"Choosing the right vector database can make or break your AI application's performance and scalability."
PINECONE
