Billing questions on tracking usage

This is a simple question. Why is it that us, peasant users, cannot track where we are with our usage to avoid billing overages? I asked chatgtp about it and I got the most astonishing response. It asked that I keep track manually of my chats!!! What? Does Open Ai has hundreds of people keeping manual track of users usage for billing purposes?:unamused: and you wonder How Deepseek is eating OAi lunch . The most advance tech in the world just told me to me to keep track with paper and pencil. embarrassing.

Haha forgot where that came from. But that is exactly what happened. I have the chats to prove it. Is idiotic for me to keep track manually.
