Error 429 Too Many Requests when calling GPT-4 API

API Feedback
1

Hi everyone,

I’m currently integrating the GPT-4 API into my application. However, whenever I send a certain number of requests, I often encounter this error: 429 Too Many Requests

I’ve already tried adding a sleep between requests, but the error still persists.

My questions are:

  1. Is there an official rate limit per minute/hour for each account?

  2. What are the best practices to avoid this error? Should I implement a queue system?

  3. Are there any differences in rate limits between GPT-4.1 and GPT-4o?

If anyone has experienced something similar or has a solution, I’d really appreciate your help :folded_hands:

Thanks in advance!
