Generative Pre-trained Transformer (GPT) is a state-of-the-art language model developed by OpenAI that utilizes deep learning techniques to generate human-like text. As an autoregressive model, GPT predicts the next word in a sentence based on the context of the preceding words, allowing it to produce coherent and contextually relevant responses. The latest iteration, GPT-3, is significantly more advanced than its predecessors, featuring a larger architecture and improved training methods. This model has a wide range of applications, from natural language processing tasks to creative writing, making it a pivotal tool in the field of artificial intelligence.
