Chat freezing after hitting fast request limit, not switching to slower model

Hello,
I’ve reached the 500 fast request limit.
I assumed that chat requests would automatically switch to a slower model (like gpt-4o-mini or cursor-small) after that — is that not the case?

Both gpt-4o-mini and cursor-small are showing 0 / no limit, and it doesn’t seem like they’re being used.
Also, whenever I try to make a request in the chat, the screen freezes.

Since this started right after the latest update, I’m wondering if there might be another issue.
If so, I’d appreciate any advice on how to resolve it.

Thank you!
