'How to tell when you've been rate limited or model downgraded?'

A Pro subscriber described the silent quality drop that hits during long sessions. The model selected in the interface never changes, but the answers do, and there is no warning when it happens. The user said responses s

'$100/mon GPT 5.5 pro hit limit very quickly.'
