It's not clear how rate limits work for gpt-3.5-turbo

I have a few questions regarding definitions ‘Free Trial Users’, ‘Pay-as-you-go users (first 48h)’, ‘Pay-as-you-go-users (after 48h)’.

  1. Could you provide examples for such definitions?

  2. I registered March 10, used ChatGPT w/o subscription. On March 19 I purchased Plus for 20 USD, started using API. What limits are applied to me?

  3. When can I achieve the limits 3,500 RPM, 90,000 TPM using gpt-3.5-turbo?

Thank you!
