Developing Apps with GPT-4 and ChatGPT

Glossary of Key Terms

This resource is designed to provide concise definitions and explanations of key terms that are introduced in this book. Many of these key terms recur throughout the chapters, and this glossary is designed to be your go-to memo.

You will find definitions of technical terms, acronyms, and concepts that are central to understanding GPT-4 and ChatGPT and using the OpenAI library.

Application programming interface (API)

A set of definitions and protocols for application interaction. An API describes the methods and data formats that a program must use to communicate with other software. For example, in the context of OpenAI, it allows developers to use GPT-4 and ChatGPT.

Artificial intelligence (AI)

A field of computer science focused on creating algorithms that can perform tasks that are traditionally the domain of human intelligence, such as processing natural language, analyzing images, solving complex problems, and making decisions.

Artificial neural network

A computational model inspired by the human brain, used in machine learning to process complex tasks. It consists of interconnected layers of nodes, or neurons, that transform input data through weighted connections. Some types, such as recurrent neural networks, are designed to process sequential data with memory elements, while others, such as those based on the Transformer architecture, use attention mechanisms to weigh the importance of different inputs. Large language models are a notable ...
