[counterintuitive] Does RAG eliminate LLM hallucinations

Treat RAG as a context-injection mechanism, not a hallucination cure. Implement robust relevance scoring, deduplication, and post-generation citation verification to prevent the model from hallucinating based on conflicting or irrelevant retrieved chunks.

Journey Context:
The common belief is that giving the model the 'right answer' in context stops it from making things up. In reality, dumping irrelevant or contradictory documents into the context window causes 'attention dilution,' forcing the model to guess which document to trust, often resulting in confabulations that combine parts of multiple chunks. RAG can actually increase hallucination if the retrieval step is noisy or returns conflicting information.
