CHAPTER 5What Is ChatGPT?

ChatGPT stands at the intersection of several advanced fields in artificial intelligence, primarily natural language processing (NLP), large language models (LLMs), and Generative AI. Each component is critical in enabling ChatGPT to understand and generate human‐like text, making it an exceptional example of the capabilities of modern AI. In this chapter, we will explore ChatGPT's skills and limitations and learn how to obtain the best results using good prompting. In the next chapters, we will learn how to transform these abilities into investment insight.

ChatGPT is built upon the principles of NLP that allow ChatGPT not just to process the literal strings of text but also to understand the context and nuance in a conversation, much like a human would. LLMs, the engines driving ChatGPT, are trained on extensive amounts of text data, enabling them to comprehend and generate language. ChatGPT's advanced natural language processing skills allow it to understand various types of textual data spanning industry reports, financial statements, earnings call transcripts, investment theses, and more.

Learning from diverse sources, encompassing various styles, topics, and language structures, allows ChatGPT to create responses that are contextually appropriate and rich in content, mirroring the depth and versatility of human language. Unlike traditional AI models that only analyze or classify data, Generative AI enables ChatGPT to produce original content. ...
