Exploring GPT-3

By: Steve Tingiris

Overview of this book

Generative Pre-trained Transformer 3 (GPT-3) is a highly advanced language model from OpenAI that can generate written text that is virtually indistinguishable from text written by humans. Whether you have a technical or non-technical background, this book will help you understand and start working with GPT-3 and the OpenAI API. If you want to get hands-on with leveraging artificial intelligence for natural language processing (NLP) tasks, this easy-to-follow book will help you get started. Beginning with a high-level introduction to NLP and GPT-3, the book takes you through practical examples that show how to leverage the OpenAI API and GPT-3 for text generation, classification, and semantic search. You'll explore the capabilities of the OpenAI API and GPT-3 and find out which NLP use cases GPT-3 is best suited for. You’ll also learn how to use the API and optimize requests for the best possible results. With examples focusing on the OpenAI Playground and easy-to-follow JavaScript and Python code samples, the book illustrates the possible applications of GPT-3 in production. By the end of this book, you'll understand the best use cases for GPT-3 and how to integrate the OpenAI API in your applications for a wide array of NLP tasks.

Understanding API authentication

Some websites are public, while others require you to log in before you can access content or functionality. The same is true for APIs. The Open-Notify API that we looked at in the Understanding APIs section is open to the public and doesn't require any kind of authentication. The OpenAI API, on the other hand, is private and therefore requires authentication to use it.

An API authentication process does the same thing as a website login, but in a way that is practical for applications rather than humans. There are many different ways in which APIs can authenticate application requests, but we're going to focus on one of the most common methods, basic authentication, because that's what the OpenAI API uses.

Basic authentication is an authentication method that is native to HTTP. It allows a username and password to be included in an HTTP header. To keep credentials secure, requests and responses to the API should be encrypted. So...
