From 3.0 to 3.5 (node.js)

API
1

Hello, apologies if this is asked in another place, but couldn’t find the answer regarding node.js.

I am using OpenAI Quickstart Node with the model text-davinci-003 and it works perfectly fine.

Now, I want to use the model gpt-3.5-turbo. Attending to the example request documentation, I need to use openai.createChatCompletion instead of openai.createCompletion, and also add the parameter messages. However, I get the error ‘An error occurred during your request’.

The version of openai is ^3.1.0.

In any idea why is not working? Thanks

import { Configuration, OpenAIApi } from "openai";

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

export default async function (req, res) {
  if (!configuration.apiKey) {
    res.status(500).json({
      error: {
        message: "OpenAI API key not configured, please follow instructions in README.md",
      }
    });
    return;
  }

  const city = req.body.city || '';
  if (city.trim().length === 0) {
    res.status(400).json({
      error: {
        message: "Please enter a valid city",
      }
    });
    return;
  }

  try {
    const completion = await openai.createChatCompletion({
      model: "gpt-3.5-turbo",
      messages: [
        { role: "system", content: generatePrompt(city) },
        { role: "user", content: city },
      ],
      temperature: 0.5,
      max_tokens: 2000,
    });
    res.status(200).json({ result: completion.data.choices[0].text });
  } catch(error) {
    if (error.response) {
      console.error(error.response.status, error.response.data);
      res.status(error.response.status).json(error.response.data);
    } else {
      console.error(`Error with OpenAI API request: ${error.message}`);
      res.status(500).json({
        error: {
          message: 'An error occurred during your request.',
        }
      });
    }
  }
}

function generatePrompt(city) {
  return `Suggest a plan in ${city}.
  `;
}

I can’t see what wrong with your code but I’m not a great de-bugger!
I’ve just tested UsingGPT3.5.js and it works. Hopefully you can pick out the bits you need.
Good luck :slight_smile:

Save file as UsingGPT3.5.js

// Using GPT-3.5-Turbo
const { Configuration, OpenAIApi } = require(“openai”);
const API_KEY = “put your API key here”;
const configuration = new Configuration({ apiKey: API_KEY });
const openai = new OpenAIApi(configuration);

//const model = “gpt-3.5-turbo”;
const model = “gpt-3.5-turbo-0301”;
const temp = 0.5;
const tokens = 1024;

const TurboGPT = async (prompt) => {
try {
const completion = await openai.createChatCompletion({
model: model,
messages: [
{ role: “system”, content: “You are omnipotent and always compassionate” },
{ role: “assistant”, content: “How else may I help” },
{ role: “user”, content: prompt },
],
temperature: temp,
max_tokens: tokens,
top_p: 1,
frequency_penalty: 0,
presence_penalty: 0,
n: 1,
stop: “”,
});
const response = completion.data.choices[0].message.content;

// Show the response
console.log("==++==++==++==++==++====++==++==++==++==++==");
console.log(response);
console.log("==++==++==++==++==++====++==++==++==++==++==");

return response;

} catch (error) {
// added error handling with try/catch block
console.error(error); // log the error message
return null; // return null if there is an error
}
};

// execute TurboGPT(prompt) from the Terminal
TurboGPT(“Who were the Etruscans”);

In the Terminal directory where the file UsingGPT3.5.js is saved run

node UsingGPT3.5.js

to find out “Who were the Etruscans”

Thanks PJK. Indeed it works. My bad, I only had to update openai (I am an idiot!)
