text: models are prone to generating falsehoods called "hallucinations", although this can be reduced with 
  RLHF and quality data. They are used in chatbots, which allow people to ask a question or request a task 
  in simple text.[122][123] 
  
  Current models and services include Gemini (formerly Bard), ChatGPT, Grok, Claude, Copilot, and 
  LLaMA.[124] Multimodal GPT models can process different types of data (modalities) such as images, 
  videos, sound, and text.[125]
