Pro uses unlimited GPT4 uses for $20, but still extra fee after 150.000?

I’m confused about the Pro version of Cursor.

It says that for $20 you get unlimited uses of GPT4.

But it also says that after using 150.000 tokens you gotta pay extra?

To me that information is conflicting. So can you please enlighten me? Should I be concerned with using GPT4 for everything so as to not rack up my monthly bill?

Or is there a distinction between GPT4 fast uses and slow uses that I am unaware of in regards to billing?

Thanks :slight_smile:
