Generative Pretrained Transformer (GPT) vs LLM

• A GPT is a type of LLM that uses deep learning to generate human-like text. 
• They are called 
  • "generative" because they can generate new text based on the input they receive, 
  • "pretrained" because they are trained on a large corpus of text data before being fine-tuned for specific tasks, and 
  • "transformers" because they use a transformer based neural network architecture to process input text and generate output text.
