GPT stands for Generative Pre-trained Transformer, which is a family of neural network models that uses the transformer architecture and is a key advancement in artificial intelligence. GPT models are designed to generate human-like text in response to a prompt, and they can be used in a wide variety of applications, such as language translation, document summarization, writing blog posts, building websites, designing visuals, making animations, writing code, and researching complex topics. The latest GPT model, GPT-3, is a large language model released by OpenAI in 2020, and it is capable of generating realistic text. GPT-3 is a type of artificial intelligence model that uses machine learning techniques to generate text.
