Why LLMs HallucinateAn LLM generates the most plausible next token given its training, with no built-in notion of truth or any source to check against, which is why it can produce confident, fluent, and completely fabricated answers. FDE loops test this because every enterprise buyer asks 'can we trust it,' and you need to explain the cause and the mitigations (grounding, refusal, citations, evals) in terms an exec will accept.🧠 Foundations of LLMs & GenAI

They are independent, and the dangerous quadrant is high relevancy with low faithfulness, which reads as a helpful, on-topic answer that the sources do not support.📊 Evaluation & ML Foundations🔒 Premium
