Why is there $120 in my account?

Hi guys,

I have a question, why is there $120 in my account?
I’m only a ChatGPT Plus subscriber. I don’t have access to GPT4 API. Do I need pay for this $120 in my account?

The 120.00 is an example. Scroll down and you will see a hard limit enterable field as well as a soft limit. Update and hit save. HTH
