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. It operates on the transformer architecture, which allows it to understand and predict language patterns effectively. GPT is pre-trained on a vast corpus of text data, enabling it to perform various language tasks such as translation, summarization, and creative writing. The latest iteration, GPT-3, boasts 175 billion parameters, making it one of the most powerful language models available. Its capabilities have revolutionized natural language processing, making interactions with AI more intuitive and human-like.
