experimental plan cutoff?

I don’t use mistral pretty regularly, but when I used to use it for a private application it was great on free tier.

But recently, I found out that all my api keys on all my accounts are rate limited for large, medium, and small models (the best one I can access is a 14b model now).

I’m not complaining (mistral needs to make money somehow) but I want to know if this is an actual cutoff (couldn’t find anything online) or if my accounts just got blocked or smth?
