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.

Classifying text from keywords

Another common text classification task is to classify documents based on keywords. To do this, we can use GPT3 to create a list of keywords that will be related to the content of the document. However, GPT3 doesn't just extract keywords from the document. It determines keywords that are relevant based on the document content. Let's try an example.

In this example, we will use the completions endpoint to classify a document based on relevant keywords.

Node.js/JavaScript example

To create the keywords classifier example in Node.js/JavaScript, follow these steps:

  1. Log in to replit.com and open your exploring-gpt3-node REPL.
  2. Create a new file – chapter08/keywords-classifier.js.
  3. Add the following code to the beginning of the keywords-classifier.js file:
    const axios = require('axios');
    const apiKey = process.env.OPENAI_API_KEY;
    const client = axios.create({
      headers: { &apos...
