Large language models (LLMs) are artificial neural networks, a particular type of artificial intelligence (AI), trained to recognize complex patterns in natural language or text to generate written content similar to what a human would produce. 1 Chatbots are specific LLM-based applications or interfaces designed to simulate human conversation, generating prompt responses to a variety of inquiries. Chatbots are now offered by several developers, but often differ in data set processing, architecture, training, number of parameters, cost, licensing, and ease of availability, among others. 1 Chat Generative Pre-trained
