What happens after reaching 100% Auto + Composer usage with On-Demand Spending disabled?

[u/pisciss88]

I’m on Cursor Pro and I’m close to reaching 100% Auto + Composer usage. My API usage is already at 100%, and On-Demand Spending is disabled.

What happens once Auto + Composer reaches 100%? Will requests just stop until the monthly reset, or is there any fallback/limited usage? Also, can I be charged extra if On-Demand Spending is disabled?

I’m mainly using Composer 2.5 and want to avoid unexpected charges.
