A chatbot, also known as an Artificial Conversational Entity (ACE), is a type of computer program or artificial intelligence system that is designed to mimic human-like conversation through auditory or textual methods. The ultimate goal of chatbots is to achieve a level of conversation that is indistinguishable from a human counterpart, thereby passing the Turing test. Chatbots find various applications in dialog systems such as customer service and information retrieval.

OpenAI has developed a chatbot called ChatGPT, which utilizes a large neural network to generate coherent and contextually appropriate responses to users. This chatbot can engage in conversations on a wide range of topics, with the ability to simulate human-like conversation.
