How does ChatGPT work?

ChatGPT stands for "Chat Generative Pre-trained Transformer." Two models of generative pre-trained transformers (GPTs) have been released to the general public: GPT 3.5 and 4.0. Each model understands and generates human-like answers to text prompts and can interact or "chat" with people. 


ChatGPT is based off hundreds of billions of words (570GB of text) that were taken from books, articles, websites, and social media. It uses complex algorithms known as "transformers" to place words in order in response to a prompt. The transformers are similar to rules that structure written and spoken languages.


When prompts are typed into the ChatGPT interface, words from your query are identified and converted to numerical "tokens" that are in turn passed through a pre-trained model to anticipate the next word in a sequence of words. When you submit your prompt, ChatGPT will return related information based the unique words that it identified. 


As of April 2023, Bing uses a testing version of the GPT-4 model, while the free version of ChatGPT is based on the older GPT 3.5-turbo model; a subscription is required to access the GPT-4 model in ChatGPT. Users of Bing Chat can watch it anticipate the next word as they type their prompt as well as watch the AI response form. In addition, Bing Chat has access to the Internet which ChatGPT does not have, so it can provide up-to-date responses on current events.
