🧠 Build Your Own RAG System in 2025 — From Query to Answer

Retrieval-Augmented Generation (RAG) = smart search + smarter LLM.

🧩 What’s inside:
• Query classifier — skip search when the model already knows
• Chunking — fixed vs semantic splits
• Embeddings — with SentenceTransformers
• FAISS vector search + re-ranking
• Summarization — clean answers from noisy text
• Lego-style pipeline: enable what you need, skip what you don’t

🚀 Bonus: Code snippets for every step — ready to copy & run.
