Codex 429 Too Many Requests
OpenAI Developer Community
June 25, 2026
Thanks for reporting this, @bobodawang.
A 429 "Too Many Requests" error usually means you've hit a rate limit, either by sending too many requests in a short period or exceeding your current usage limits. (OpenAI Help Center)
A few things worth trying:
* Wait a short time and try again, since rate limits reset automatically.
* If you're using the API or Codex programmatically, add exponential backoff so retries are spaced out instead of happening immediately. Repeated retries can actually extend the problem. (OpenAI Help Center)
* Check your current rate limits and usage tier in your account settings. If you're consistently hitting the limit, you may need a higher usage tier. (OpenAI Help Center)
If you're seeing this in the ChatGPT Codex experience rather than the API, let us know a bit more about where the error appears (web, desktop, CLI, etc.) and someone here can help narrow it down.
