Claude 4T extremely slow/breaking

Describe the Bug

Since yesterday I’ve noticed Claude 4T becoming extremely slow or simply not working with the message “Errored, Not Charged”.

I can’t find any announcement that there is a performance issue nor any indication that this is price related.

So what is going on?

Steps to Reproduce

Every single Claude 4T request has this issue.

Operating System

MacOS

Current Cursor Version (Menu → About Cursor → Copy)

Does this stop you from using Cursor

Yes - Cursor is unusable

I’m the same, it’s very slow, sometimes it fails to call the tool, and sometimes it gets stuck in the entire request processing and keeps waiting
