2026 में AI एप्लिकेशन के लिए सर्वश्रेष्ठ वेक्टर डेटाबेस
Vector databases for AI applications have become essential infrastructure for RAG (Retrieval-Augmented Generation), semantic search, and recommendation systems in 2026. The best vector databases—Pinecone, Milvus, Qdrant, Weaviate, Chroma, pgvector, and Elasticsearch—provide efficient similarity search over high-dimensional embeddings at scale. Choosing vector databases requires evaluating query latency, index types (HNSW, IVF), deployment models (managed vs self-hosted), and cost structures. Pinecone excels as a fully managed solution with minimal operations, while Milvus provides maximum control for self-hosted deployments. Qdrant offers Rust-based performance with Docker simplicity, and pgvector extends PostgreSQL with vector capabilities. Vector database performance directly impacts RAG application quality—slow retrieval degrades LLM response times and increases costs. For teams building LLM applications, vector database selection is as critical as model choice. ...
