Problem

Confirm this is a Node library issue and not an underlying OpenAI API issue - [X] This is an issue with the Node library Describe the bug Previously in v3, I am able to track my current usage and token limit since the chat completion response is an axios response, so I can use `response.headers` like so, but now chat completion response is `OpenAI.Chat.Completions.ChatCompletion` which representing `response.data` in v3 only How I can get the same behaviour in v4? Thank you in advance [code block] To Reproduce 1. Call create chat completion function 2. Response does not contains header Code snippets [code block] OS macOS Node version Node v18.16.1 Library version openai v4.16.1

Retrieve Response Headers in OpenAI Node Library v4

Medium Risk

In OpenAI Node library v4, the response structure for chat completions has changed. The response is now encapsulated within a specific object (OpenAI.Chat.Completions.ChatCompletion) that does not expose the HTTP response headers directly, unlike the previous version where headers were accessible through the axios response object.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Install Axios

    Ensure that axios is installed in your project as it will be used to make the API request and access the headers.

    bash
    npm install axios
  2. 2

    Modify API Call to Use Axios

    Instead of using the OpenAI library's method directly, use axios to make the request to the OpenAI API endpoint for chat completions. This allows you to access the headers from the response.

    javascript
    const axios = require('axios');

async function getChatCompletion(prompt) {
  const response = await axios.post('https://api.openai.com/v1/chat/completions', {
    model: 'gpt-4',
    messages: [{ role: 'user', content: prompt }]
  }, {
    headers: { 'Authorization': `Bearer YOUR_API_KEY` }
  });
  return response;
}
  3. 3

    Access Response Headers

    After modifying the API call, you can now access the response headers directly from the axios response object. This allows you to track rate limits and usage effectively.

    javascript
    const response = await getChatCompletion('Hello, how are you?');
console.log('Rate Limit:', response.headers['x-ratelimit-limit']);
console.log('Remaining Requests:', response.headers['x-ratelimit-remaining']);
  4. 4

    Handle Errors Gracefully

    Ensure to implement error handling to catch any issues with the API request, which will help in debugging and maintaining the application.

    javascript
    try {
  const response = await getChatCompletion('Hello, how are you?');
} catch (error) {
  console.error('Error fetching chat completion:', error.response ? error.response.data : error.message);
}

Validation

Confirm the fix by making a chat completion request and checking the console for the rate limit headers. Ensure that the headers are logged correctly and reflect the current usage.
