A very good W3school tutorial can be found here.

OpenAI api in node.js, javascript

I am using openai API on javascript. Below is my code.

require('dotenv').config();

const OpenAI_Api = process.env.OpenAIApi || 'Mykey';

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

const configuration = new Configuration({
        apiKey: OpenAI_Api
        });

const openai = new OpenAIApi(configuration);

const createChatCompletion = async () => {
  try {
    const response = await openai.createChatCompletion({
      model: 'gpt-4.0',
      messages: [
        { role: 'system', content: 'You are a helpful assistant.' },
        { role: 'user', content: 'Who won the world series in 2020?' },
        { role: 'assistant', content: 'The Los Angeles Dodgers won the World Series in 2020.' },
        { role: 'user', content: 'Where was it played?' },
        { role: 'assistant', content: 'The World Series was played in Arlington, Texas at the Globe Life Field.' },
      ],
    });

    console.log(response.choices[0].message.content); // Display the generated response
  } catch (error) {
    console.error('Error creating chat completion:', error);
  }
};

createChatCompletion();

It is saved in chatgpt.js. However, when I run node chatgpt.js, I receive the error.

const configuration = new Configuration({
^

    Your implementation is based on v3 but you’re using v4. This comes with some changes.

    First of, the initialization is a bit different, there is no use of a Configuration object anymore. Furthermore the openai.createChatCompletion is moved to openai.chat.completions.create.

    I’ve reflected these changed in the code you’ve provided.

    import dotenv from 'dotenv';
import OpenAI from 'openai';

dotenv.config();

const OpenAI_Api = process.env.OpenAIApi || 'Mykey';

const openai = new OpenAI({
  apiKey: OpenAI_Api
});

const createChatCompletion = async () => {
  try {
    const chatCompletion = await openai.chat.completions.create({
      model: "gpt-4",
      messages: [
        { role: 'system', content: 'You are a helpful assistant.' },
        { role: 'user', content: 'Who won the world series in 2020?' },
        { role: 'assistant', content: 'The Los Angeles Dodgers won the World Series in 2020.' },
        { role: 'user', content: 'Where was it played?' },
        { role: 'assistant', content: 'The World Series was played in Arlington, Texas at the Globe Life Field.' },
      ],
    });
    console.log(chatCompletion.choices[0].message);
  } catch (error) {
    console.error('Error creating chat completion:', error);
  }
};

createChatCompletion();

    What you’re trying to use worked with the OpenAI Node.js SDK <v4.

    As you said, you’re using v4.26.0, so the following is the correct initialization:

    import OpenAI from 'openai';

const openai = new OpenAI({
  apiKey: process.env['OPENAI_API_KEY'],
});

    But you also made some other mistakes:

    • using the wrong method name (i.e., createChatCompletion, which works with <v4)
    • using an incorrect model name (i.e., gpt-4.0, which does not exist)

    The following is the correct full code:

    import OpenAI from 'openai';

const openai = new OpenAI({
  apiKey: process.env['OPENAI_API_KEY'],
});

const createChatCompletion = async () => {
  try {
    const response = await openai.chat.completions.create({
      model: 'gpt-4',
      messages: [
        { role: 'system', content: 'You are a helpful assistant.' },
        { role: 'user', content: 'Who won the world series in 2020?' },
        { role: 'assistant', content: 'The Los Angeles Dodgers won the World Series in 2020.' },
        { role: 'user', content: 'Where was it played?' },
        { role: 'assistant', content: 'The World Series was played in Arlington, Texas at the Globe Life Field.' },
      ],
    });

    console.log(response.choices[0].message.content);
  } catch (error) {
    console.error('Error creating chat completion:', error);
  }
};

createChatCompletion();
