Why do LLMs Hallucinate?

LLMs hallucinate because they are not databases. They predict likely text, not guaranteed truth. RAG helps, but only when retrieval finds the right context. In production AI systems, hallucination is a failure mode you manage with grounding, citations, evals, abstention, and better retrieval quality. #AI #LLM #RAG #MachineLearning #SoftwareEngineering #GenerativeAI
