ChatGPT is a sophisticated AI language model that relies on two primary artificial intelligence techniques: Natural Language Processing (NLP) This allows the AI to understand, interpret, and generate human language. It deals with the interaction between computers and human (natural) languages. Deep Learning techniques ChatGPT is built upon a type of neural network architecture called a Transformer, which is a deep learning model. Deep learning involves training complex neural networks with many layers to learn intricate patterns from vast amounts of data.
