Artificial human companions may be any kind of hardware or software creation designed to give companionship to a person.[1] Various types of Large Language Models (LLMs) are used in the development of AI-based human companions.[2] These can engage in natural, dynamic conversations, provide assistance, offer companionship, and even perform tasks like scheduling or information retrieval.[3] Examples include digital pets, such as the popular Tamagotchi, or robots, such as the Sony AIBO. Virtual companions can be used as a form of entertainment, or they can be medical or functional, to assist the elderly in maintaining an acceptable standard of life.
