Zero-shot prompting

An AI prompting technique where the model is asked to perform a task with no prior examples in the prompt, only an instruction or description, relying entirely on its pretrained knowledge to infer how to complete the task

The Explain card

Plain English
Zero-shot prompting asks the model to perform a task with only an instruction or description, no examples, relying entirely on what it learned during pretraining.
Example
"Classify this email as phishing or legitimate" with the email pasted below. No sample emails are given. The model uses its general knowledge of phishing patterns to decide, which works well for common cases and less well for unusual ones.
Why it matters
Zero-shot is quick and cheap, but behaviour is less predictable because the model interprets the task from scratch. Defenders should expect more variance and test edge cases before trusting zero-shot outputs in a security workflow.
Hook
Zero-shot means zero examples: the model wings it from memory.

Word knowledge

How the word is built, where it came from, and what it sits beside in memory.

In a sentence

The mail gateway's phishing pipeline applies zero-shot prompting to each inbound message and writes phishing or legitimate into the ticket field.

Why these words
  • zero-shot Arabic sifr, empty, via Italian zero, plus Old English sceot, a missile or a try borrows the film-set count of takes, so the prompting is done with none rather than a stack of them
  • prompting Latin promptus, brought forth, from promere, plus English -ing names the cue-writing, so the hyphenated count is a way of prompting rather than a way of shooting film
Where it came from
Origin
English collocation on the zero-shot pattern, from Arabic sifr (empty, via Italian zero) and Old English sceot (a missile, a try), plus Latin promptus (brought forth, from promere) as a gerund
Entered the language
c. 2020
What changed
Zero had named the numeral since the early 1600s, from Arabic sifr via Italian. Shot had meant a missile, then a try, then a photographic exposure, then a film take. English hyphenated a count to shot for a magazine issue, a circuit pulse, or a stunt finished in a given number of takes. Vision papers around 2009 borrowed zero-shot for learning a class with no labeled picture of it. The GPT-3 paper of 2020 hung the same hyphen on prompting, and the three-word label became the ordinary name for that prompting count.
How it is spelled
Pattern
hyphen joins a count-word to a noun used as an adjective: zero-shot, not zeroshot or zero shot
Pattern
Latin -pt- stays a cluster, never simplified to -t-
Pattern
-ing turns a verb into a noun of activity
Breaks the pattern
zero-shot keeps its hyphen as a unit; prompting stays a free word
Breaks the pattern
shot is noun, verb, and past of shoot with no spelling change
Breaks the pattern
zero dropped the Italian and French accent of zéro and is not spelled like cipher, from the same Arabic sifr
