ChatGPT Error Code 429

You exceeded your current quota, please check your plan and billing details

Cause: You have hit your maximum monthly spend (hard limit) which you can view in the account billing section
Solution:Apply for a quota increase.

This error message denotes that you’ve reached your assigned usage limit for the API, indicating that too many tokens or requests have been submitted in a brief span, exceeding the permitted number. This could arise from several situations, such as:

  • Frequent or concurrent requests made through a loop or a script.
  • Sharing your API key among different users or applications.
  • Usage of a free or low-tier plan which has a low rate limit.

To rectify this error, consider the following steps:

  1. Regulate your requests and avoid any unnecessary or redundant calls.
  2. If a loop or a script is in use, ensure you implement a backoff mechanism or retry logic that adheres to the rate limit and response headers.
  3. If your organization is shared with other users, remember that the limits apply per organization, not per user. Thus, it’s worth checking the usage levels of your team members as their activities also contribute to the limit.
  4. If you’re on a free or low-tier plan, you might want to think about upgrading to a pay-as-you-go plan, which provides a higher rate limit. You can review constraints of each plan in rate limit guide.

ChatGPT Error Code 429

The engine is currently overloaded, please try again later

Cause: OpenAI servers are experiencing high traffic. 
Solution: Please retry your requests after a brief wait.

This error message signifies that you’ve reached your maximum monthly expenditure for the API. Your maximum monthly limit, referred to as the ‘hard limit’, can be found in your account billing settings. This implies that you’ve exhausted all credits allotted to your plan, reaching the cap of your current billing cycle. This can occur due to several reasons, including:

  • Utilizing a high-volume or intricate service that consumes a significant amount of credits or tokens.
  • Setting your limit too low relative to your organization’s usage.

To rectify this error, please adhere to the following steps:

  1. Review your current quota within your account settings. You can see how many tokens your requests have used up in the usage section of your account.
  2. If you’re on a free plan, consider upgrading to a pay-as-you-go plan that provides a higher quota.
  3. If you need a higher quota, you can apply for an increase by providing relevant details on anticipated usage. We’ll review your request and respond within approximately 7-10 business days.

This error message signifies that servers are currently overloaded due to high traffic and are unable to process your request at this time. Such a situation can arise due to several factors, including:

  • A sudden surge or increase in demand for API services.
  • An unexpected or unavoidable service disruption or incident occurring on servers.
