People ask ChatGPT & their fellow LLMs questions every day, but how much does a chatbot (LLM) really know? This presentation will address this question by drilling into some details of organismal biology, asking four different chatbots, for example, what do they know about snakes? While this sounds very specific, it addresses the general problem of how much information an LLM covers, its accuracy, sources, hallucinations, and other problems that chatbots promise to solve, but … don’t. Peter Uetz will present some results he found with a group of students and VCU collaborators.
