GPT stands for Generative Pretrained Transformer. It is a machine learning model of neural networks that is trained using data from the Internet to generate any type of text. This sophisticated neural network is used to train extensive language models (LLM) to simulate human communication. ChatGPT is a direct descendant of GPT-3 and is a sophisticated form of a sophisticated machine learning algorithm called a neural network.
GPT is an architecture based on Transformers and a training procedure for natural language processing tasks. First, a language modeling objective is used on unlabeled data to learn the initial parameters of a neural network model. These parameters are then adapted to a target task using the corresponding supervised objective.
