Explanation of OpenAI and GPT and their underlying technologies

OpenAI is an AI research lab with a goal to advance AI technology safely and for the betterment of humanity. Its research areas include natural language processing, robotics, and machine learning. Generative Pre-trained Transformer (GPT) is a language model developed by OpenAI that uses deep learning to generate human-like text based on a given prompt. GPT is based on a type of artificial neural network called a transformer, which was introduced by Google researchers in 2017. Transformers use self-attention to focus on specific parts of the input text to generate output text.
