Quick Answer

What is Prompt Engineering?

Prompt Engineering is the practice of designing instructions that get useful, accurate output from AI models.

Definition

Prompt Engineering is the discipline of writing effective inputs — instructions, examples and constraints — for large language models. It combines clear thinking, structured writing and an understanding of how models interpret context.

Real-world examples

  • Giving the model a role: 'You are a financial analyst…'
  • Providing few-shot examples of the desired output.
  • Asking the model to think step by step for reasoning tasks.

Common mistakes

  • Writing vague, one-line prompts and expecting expert output.
  • Forgetting to specify the desired format.
  • Not verifying facts in the model's response.
