RAG Fundamentals

Intermediate 33 min 5 Bytes AI Engineering

Build a real retrieval-augmented generation pipeline — chunks, embeddings, retrieval, reranking, evals.

What you'll cover

  • RAG in 10 minutes The smallest possible retrieval-augmented generation pipeline you can ship.
  • Vector DB basics What an embedding store actually does, and when you don't need one.
  • Semantic chunking Why naive text splitting wrecks RAG quality, and what fixes it.
  • Rerankers, explained Cross-encoders, cohere rerank, recall@k vs precision@k.
  • Evals for LLM apps Pairwise, rubric, golden sets.
