[counterintuitive] Does RAG eliminate LLM hallucinations

Treat RAG as context injection, not a hallucination cure. Implement robust retrieval evaluation, chunking strategies, and citation verification, because noisy or conflicting context actually increases hallucination rates.

Journey Context:
The prevailing belief is that giving the model the 'right' data stops it from making things up. In reality, LLMs suffer from 'attention dilution' when presented with multiple retrieved chunks. If the retrieved context doesn't perfectly answer the query, or if chunks conflict, the model will happily hallucinate by mixing entities across chunks or generating plausible but ungrounded continuations. RAG shifts the failure mode from 'fabricating from pre-trained weights' to 'fabricating from misaligned context'.
