Rag

RAG fixes the core problems with pure LLMs — hallucination, stale knowledge, private data — by making retrieval a first-class citizen. Here’s the full technical picture: vector search, hybrid retrieval, GraphRAG, agentic patterns, and what a production stack actually looks like in 2026.

The storage format you choose for AI knowledge directly shapes your system’s latency, token density, and semantic clarity. A pragmatic breakdown of when to use raw Markdown, when to build a RAG pipeline, and why the best production systems use both.
