text: **GPT**
  
  Generative pre-trained transformers (GPT) are large language models (LLMs) that generate text based on 
  the semantic relationships between words in sentences. Text-based GPT models are pretrained on a large 
  corpus of text that can be from the Internet. The pretraining consists of predicting the next token (a token 
  being usually a word, subword, or punctuation). Throughout this pretraining, GPT models accumulate 
  knowledge about the world and can then generate human-like text by repeatedly predicting the next 
  token. Typically, a subsequent training phase makes the model more truthful, useful, and harmless, 
  usually with a technique called reinforcement learning from human feedback (RLHF). Current GPT
