Semantic search matches intent through geometry, not keywords.
Keyword search wins on identifiers; semantic search wins on intent—hybrid approaches handle both.
Hybrid retrieval outperforms pure vector or keyword search for real-world RAG systems.
Retrieval beats fine-tuning for enterprise AI deployment speed and cost.
Errors in early pipeline stages propagate invisibly through to final answers.
Explore query transformations and routing strategies to fix sequential RAG's retrieval failures.
Learn the three-stage architecture that makes production AI systems work reliably.
RAG cuts hallucinations by up to 71% but still fails in specialized domains.
Optimize each RAG phase together, not in isolation, to avoid silent failures.
