Why does AI make things up instead of just saying, “I don’t know”? Because an LLM isn’t checking reality before every sentence—it’s predicting what text is most likely to come next. And sometimes the most plausible-sounding answer is completely wrong. That’s how you get fake studies, fake citations, and answers delivered with total confidence. Plausibility ≠ truth. #AI #ArtificialIntelligence #ChatGPT #MachineLearning #LLM
