Outdated Info Lurks in LLMs: How Token Probabilities Create Logical Inconsistencies

Large Language Models (LLMs) like ChatGPT, trained on massive internet datasets, often grapple with conflicting or outdated information. This article uses the height of Mount Bartle Frere as a case study, showing how LLMs don't always prioritize the most recent data. Instead, they predict based on probability distributions learned from their training data. Even advanced models like GPT-4o can output outdated information depending on subtle prompt variations. This isn't simple 'hallucination,' but a consequence of the model learning multiple possibilities and adjusting probabilities based on context. The author highlights the importance of understanding LLM limitations, avoiding over-reliance, and emphasizing transparency.
