A limit on how much AI you can use in a set time.
A usage cap is like a pizza shop on Friday night. You want a third slice, but the oven says, “Buddy, I need a nap.”

GPU

TPS
Beyond the quota, generation speed also changes how the service feels.
AI data center
A usage cap often reflects the cost pressure behind the data center.
