Zero-shot Prompting
Asking an AI to do something directly, without giving it any examples to copy from. You state the task and let the AI rely on what it already knows. Because you are giving zero examples, this is called zero-shot prompting.
Sometimes you can ask an AI to do a task straight out, with no worked examples, and it handles it fine. That is zero-shot prompting. The “zero” refers to the number of examples you provide, which is none. You describe what you want, and the AI draws on its training to work it out.
For instance, you might type “Translate this sentence into French” or “Summarise this paragraph in one line” and get a solid result immediately. You did not show the AI a sample translation or a model summary first. You trusted it to know how, and for common, well-understood tasks it usually does.
This is the way most people naturally use AI, often without realising there is a name for it. It works well when the task is familiar and your instruction is clear. The clearer your prompt, the more reliable a zero-shot request becomes.
When zero-shot falls short, usually because the task is unusual or you want a very specific style, the fix is to show a couple of examples. That approach is called few-shot prompting, and knowing when to reach for it is a small but useful part of prompt engineering.
