[counterintuitive] Does RAG eliminate LLM hallucinations
Treat RAG as context augmentation, not a hallucination cure. Implement citation enforcement, retrieval evaluation, and graceful fallbacks because LLMs can still hallucinate within the provided context or ignore it entirely.
Journey Context:
The belief is that giving the model the right facts stops it from making things up. In reality, LLMs suffer from 'context ignorance' where they blend retrieved context with parametric memory. If the retrieved context is contradictory, overwhelming, or misaligned with the query, hallucination rates can actually increase compared to zero-shot, as the model feels compelled to use the provided context inappropriately.
