Generative Artificial Intelligence represents an advanced class of models designed to create original content that reflects the characteristics of an initial dataset. It can be described as a model capable of generating human-like text in response to a prompt (i.e., a command or an invitation to provide a response). Given an incomplete sentence, it can suggest a completion; given an initial phrase, it can develop entire paragraphs; given a question, it can provide plausible answers; with a topic and some basic information, it can craft an essay; given a fragment of dialogue, it can continue the conversation with a coherent transcription.
