Hybrid Retrieval: The Architectural Backbone Behind Reliable AI Systems
Most AI failures don’t happen inside the model. They happen one layer earlier — in retrieval. If your RAG system, copilot, or agentic workflow is hallucinating, the LLM probably isn’t “dumb.” It’s operating on bad context. Dense search alone can’t fix that. Sparse search alone can’t fix that. Hybrid retrieval — the combination of semantic…
