WTF? Chat GPT4 capped at 21 "messages" in a 4.5 Hour period

I began using Chat GPT4 at 8am by 12:30pm and sent just 21 messages, yet I got the error “You’ve reached the current usage cap for GPT-4. You can continue with the default model now, or try again after 1:06 PM.”

Considering I am meant to be able to send 40 messages in a three hour window - there must be some bug.

Hey there and welcome to the community!

This is a known problem. Apparently, OpenAI is experimenting with “dynamic” limits, but there’s no official word on that yet.
