API Key Rate Limit Discrepancy and Quota Issues

I am experiencing a problem with the rate limits on my API key. My account is on Tier 2, which should grant me up to 5,000 requests per minute (RPM) for the gpt-4o-mini model, as shown in my limits page:

  • Model: gpt-4o-mini

  • Shared limits: 2,000,000 TPM, 5,000 RPM, 20,000,000 TPD

However, when I use my API key, I am consistently receiving a 429 rate limit error stating that my RPM limit is 3 requests per minute.

Additionally, when I try to use other models like gpt-4o and text-embedding-3-small, I get insufficient quota errors, even though my account tier and limits indicate otherwise.

Could you please help me understand why my API key is limited to only 3 RPM despite my account tier and shared limits? Also, why do I get insufficient quota errors on other models?
