Input quota

The maximum amount of data or the maximum number of requests a user or application can send to an AI system within a time frame

The Explain card

Plain English: An input quota is the maximum amount of data or number of requests a user or application may send to an AI system within a time frame.
Example: An API key is limited to a few hundred requests per hour and a fixed token budget per day. When a compromised script starts hammering the endpoint at midnight, the quota cuts it off long before the bill or the model's patience runs out.
Why it matters: Quotas limit the damage from stolen keys, denial-of-wallet attacks, and automated probing used for model extraction. They also make abuse visible, since hitting the ceiling is a signal worth alerting on.
Hook: An input quota is a speed limit on the model's front door.

In a sentence

The inference gateway stops the API key at the input quota of 400 requests per hour and returns HTTP 429 on the next call.

Why these words

input English in + put, from Old English putian, to thrust names the inbound stream the allotment is measured against, not the model's reply
quota Latin quota, how great a part, from quotus, of what number is the head noun, the allotted share that the first word pins to that inbound stream

Where it came from

Origin: English computing collocation from English in + put (Old English putian, to thrust) and Latin quota (how great a part, from quotus, of what number)
Entered the language: 2010s
What changed: Input first named a contribution of money or labour in the 1700s, then the data fed into a computer. Quota entered English in the 1600s as a proportional share, later a hard allotment of immigrants or imports, then of disk space and API calls. Cloud platforms of the 2010s joined the two words for the inbound cap a client key hits, and AI inference gateways kept the pair.

How it is spelled

Pattern: English in- before p stays in, unlike Latin in- which becomes im- as in import
Pattern: Latin qu- stays qu for /kw/
Pattern: quota keeps Latin feminine -a, unlike quote from the same quotus
Breaks the pattern: the noun phrase stays two words; the hyphen appears only when it modifies another noun
Breaks the pattern: input keeps n before p because it is English in + put, not a Latin compound
