In November 2022, worldwide online search interest for a three-letter acronym (GPT) barely registered. Since then, interest has skyrocketed—if you thought the boom in metaverse interest 12 months ago was big, it is dwarfed in comparison (see chart below). GPT stands for Generative Pre-trained Transformer. GPT-3.5 is one of the largest and most advanced language models currently available. ChatGPT, released by OpenAI in November 2022, essentially works as a chatbot, enabling users to ask questions and follow-up questions. Since its launch, users have tested the technology with university exam questions, poem requests and even computer code.
