Simple definition
A prompt is an instruction or input supplied to an AI model to guide the task and resulting output.
Purpose and use
A prompt supplies a task and optionally context, examples or output constraints to a model.
How does it work?
Interpretation depends on the model, conversation format and other instructions or data included in the input.
Example and verification
For repeated tasks, specify expected output and evaluate representative examples, including missing or ambiguous information.
Points to watch
A prompt replaces neither technical authorization nor result validation. Long or contradictory instructions can reduce quality.
In short
A clear request helps the model, but success must be assessed on the actual task.
