What is ChatGPT and how does it work?
Chat Generative Pre-trained Transformer (ChatGPT) is a very large natural language processing model that uses deep learning algorithms trained on vast amounts of internet data to generate human-like responses to user prompts. It was developed by a company called OpenAI and released in November 2022 [1].
Transformers are an architecture used primarily in the field of natural language processing, that aims to solve sequence-to-sequence tasks (e.g. language translation, which amounts to predicting a sequence of words in a target language from a sequence of words in a source language) while handling long-range dependencies with ease. They provide superior answers while requiring less training time than previous approaches such as recurrent neural networks [2]. In short, ChatGPT examines the words provided as input by the users, and predicts what words will follow while generating a coherent response in a human-like style. It has been fine-tuned for a myriad of language tasks including text generation and completion, translation, sentiment analysis, document summarisation, question and answering, and even generation and explanation of programming code [1].
So far, ChatGPT passed the Wharton MBA examination, law school examinations, United States Medical Licensing Examination (USMLEs), and more [3, 4]. Its role has been explored in different specialties including intensive care medicine, with variable results [5, 6]. How much of ChatGPT’s “textbook” knowledge remains applicable to “real world” patients remains to be demonstrated.
