The full form of “GPT” is “Generative Pre-trained Transformer.” GPT is a type of artificial intelligence language model developed by OpenAI. GPT models, such as GPT-3 (Generative Pre-trained Transformer 3), are designed to understand and generate human-like text based on the input they receive. These models are pre-trained on vast amounts of diverse data and can perform various natural language processing tasks, making them versatile tools in language-related applications.
