Five advanced RAG architectures explained: Contextual, Multimodal, Hybrid, GraphRAG and Agentic

A thread breaks down five advanced RAG architectures: Contextual RAG (attach context notes to chunks before storing), Multimodal RAG (search page images directly so tables/charts survive), Hybrid Search (combining semantic and keyword retrieval), GraphRAG (mapping entity relationships into clustered, pre-summarized groups), and Agentic RAG (iterative agent-driven retrieval instead of one-shot search).
