Quick Answer
AI predicts the next most likely word, not truth. It has no concept of facts, only patterns.
Detailed Answer
Language models generate text by predicting statistically likely next words based on training patterns. They do not have a fact database or truth-checking mechanism. When the model encounters a gap in its training data, it fills it with plausible-sounding but fabricated content. This is why AI confidently states false information. Retrieval-augmented generation (RAG) and tools like Perplexity that ground responses in sources are the current best solutions.
