How can I use Premium models in free plan?

How do I use Premium models in the free plan?
Does it mean that I have to enter my API key?
Or how to use them in Cursor at all?
I think I used 2 queries by accident, but I don’t remember what I did then

Premium models 0 / 500
You’ve used no requests out of your 500 fast requests quota.

gpt-4o-mini or cursor-small0 / No Limit
You’ve used 0 fast requests of this model. You have no monthly quota.

I receive the following notification for any method of use (except for paid models)

Our servers are currently overloaded for non-pro users, and
you’ve used your free quota. Please try again in a few minutes. If
you think this is a mistake, please contact hi@cursor.sh

Make sure you’re logged into Cursor with the right email.

Thanks. I logged out and logged in to my account, everything is working now, but it’s interesting that all the quotas have reset to zero :thinking:
