TypeError: openai.createChatCompletion is not a function

Getting this error whenever I try to run the code from the video.

require('dotenv').config(); const { Client, IntentsBitField } = require('discord.js'); OpenAI = require('openai');

const client = new Client({ intents: [ IntentsBitField.Flags.Guilds, IntentsBitField.Flags.GuildMessages, IntentsBitField.Flags.MessageContent, ] })

client.on('ready', () => { console.log('ChatGPT is online'); })

const openai = new OpenAI({ apiKey: process.env.API });

client.on('messageCreate', async (msg) => { if(msg.author.bot) return; if(msg.channel.id !== process.env.CHANNEL) return; if(msg.content.startsWith('!')) return;

let conversationLog = [{
    role: 'system',
    content: 'You are a friendly chatbot'
}]

await msg.channel.sendTyping();

let previousMessages = await msg.channel.messages.fetch({ limit: 15 });
previousMessages.reverse();

previousMessages.forEach((message) => {
    if(msg.content.startsWith('!')) return;
    if(message.author.id !== client.user.id && msg.author.bot) return;
    if(message.author.id !== msg.author.id) return;

    conversationLog.push({
        role: 'user',
        content: message.content,
    })
})

const res = await openai.createChatCompletion({
    model: 'gpt-3.5-turbo',
    messages: conversationLog,
});

msg.reply(res.data.choices[0].message);

});

client.login(process.env.TOKEN);
