<p>We have detected a large number of <strong>429 errors</strong> for <code>/v1/chat/completions</code> requests in our backend logs. These errors occur dozens of times per minute on average, but they contain no account information or requested model details.</p><p>This situation usually happens when you are sending requests with an invalid or non-existent API key. It is possible that you previously created an API key and later deleted it, but your client is still using the old, invalid API key.</p><p>Please check your client’s API key configuration and make sure it is using a valid API key to avoid unnecessary request failures.</p><p>Thank you for your cooperation.</p>
