openai

What is openai?

The openai npm package is a Node.js client library for accessing the OpenAI API, which provides access to powerful AI models such as GPT-3 for natural language processing tasks, including text generation, translation, summarization, and more. The package allows developers to easily integrate OpenAI's AI capabilities into their Node.js applications.

What are openai's main functionalities?

Text Completion

Generates text completions for a given prompt using the GPT-3 model.

const { Configuration, OpenAIApi } = require('openai');

const configuration = new Configuration({
  apiKey: process.env.OPENAI_API_KEY,
});
const openai = new OpenAIApi(configuration);

openai.createCompletion({
  model: 'text-davinci-003',
  prompt: 'Translate the following English text to French: Hello, how are you?',
  max_tokens: 60
}).then(response => {
  console.log(response.data.choices[0].text);
});

Text Classification

Classifies a piece of text into one of the specified categories.

const { Configuration, OpenAIApi } = require('openai');

const configuration = new Configuration({
  apiKey: process.env.OPENAI_API_KEY,
});
const openai = new OpenAIApi(configuration);

openai.createClassification({
  model: 'text-davinci-003',
  examples: [
    ['A movie about space wars and intergalactic politics', 'Science Fiction'],
    ['A film focusing on the love life of a New York City woman', 'Romance']
  ],
  query: 'A story about a boy who learns he is a wizard and attends a magical school',
  labels: ['Science Fiction', 'Romance', 'Fantasy']
}).then(response => {
  console.log(response.data);
});

Text Summarization

Summarizes a longer piece of text into a concise version.

const { Configuration, OpenAIApi } = require('openai');

const configuration = new Configuration({
  apiKey: process.env.OPENAI_API_KEY,
});
const openai = new OpenAIApi(configuration);

openai.createCompletion({
  model: 'text-davinci-003',
  prompt: 'Summarize the following text: ...',
  max_tokens: 60,
  temperature: 0.7
}).then(response => {
  console.log(response.data.choices[0].text);
});

Other packages similar to openai

watson-developer-cloud

This package provides access to IBM Watson's AI services, which include natural language processing, speech to text, text to speech, and language translation. It is similar to openai in providing AI-powered language services, but it uses IBM's Watson AI instead of OpenAI's models.

google-cloud

The Google Cloud npm package allows developers to interact with Google Cloud services, including its AI and machine learning services like the Natural Language API and the Translation API. It offers functionalities similar to openai but is integrated with Google's cloud ecosystem.

microsoft-cognitiveservices-speech-sdk

This package is part of Microsoft's Azure Cognitive Services and provides capabilities for speech recognition, text-to-speech, and speech translation. It offers different services compared to openai, focusing more on speech technologies rather than text-based AI models.

README

OpenAI Node.js Library

The OpenAI Node.js library provides convenient access to the OpenAI API from Node.js applications. Most of the code in this library is generated from our OpenAPI specification.

Important note: this library is meant for server-side usage only, as using it in client-side browser code will expose your secret API key. See here for more details.

Installation

$ npm install openai

Usage

The library needs to be configured with your account's secret key, which is available on the website. We recommend setting it as an environment variable. Here's an example of initializing the library with the API key loaded from an environment variable and creating a completion:

const { Configuration, OpenAIApi } = require("openai");

const configuration = new Configuration({
  apiKey: process.env.OPENAI_API_KEY,
});
const openai = new OpenAIApi(configuration);

const completion = await openai.createCompletion("text-davinci-001", {
  prompt: "Hello world",
});
console.log(completion.data.choices[0].text);

Check out the full API documentation for examples of all the available functions.

Request options

All of the available API request functions additionally contain an optional final parameter where you can pass custom axios request options, for example:

const completion = await openai.createCompletion(
  "text-davinci-001",
  {
    prompt: "Hello world",
  },
  {
    timeout: 1000,
    headers: {
      "Example-Header": "example",
    },
  }
);

Error handling

API requests can potentially return errors due to invalid inputs or other issues. These errors can be handled with a try...catch statement, and the error details can be found in either error.response or error.message:

try {
  const completion = await openai.createCompletion("text-davinci-001", {
    prompt: "Hello world",
  });
  console.log(completion.data.choices[0].text);
} catch (error) {
  if (error.response) {
    console.log(error.response.status);
    console.log(error.response.data);
  } else {
    console.log(error.message);
  }
}

Thank you to ceifa for creating and maintaining the original unofficial openai npm package before we released this official library! ceifa's original package has been renamed to gpt-x.
