There is great interest in understanding the errors that generative AI makes. As this technology spreads across fields, from healthcare to marketing, its reliability is coming under increased scrutiny. Notable errors include hallucinations, reasoning errors, and factual errors. The potential impact of these errors is profound, particularly in fields such as medical diagnosis or military planning where lives are at stake. Some AI errors raise ethical questions particularly when they arise from biases in the training sets. Errors due to biases in the training set raise questions about the accountability of the developers of generative AI systems.As AI research and applications accelerate, understanding the nature and scope of these errors becomes ever more critical. By understanding the limitations of generative AI, both developers and end users can make appropriate adjustments and maximize the benefits while minimizing the risks.In this paper, we describe eight errors, five of which we have not seen mentioned in the literature previously, that generative AI is making as of December, 2024. Seven of these problems are very simple for humans, like finding the optimal move in a tic-tac-toe game. The seventh problem is more difficult but the error that the AI makes can be identified by a layperson. We have run these problems through many generative AI foundation models but in this paper we concentrate on ChatGPT 4o-latest and Claude-3.5.-Sonnet.
