Prompt Engineering

Definition

Prompt Engineering is the discipline of designing inputs to an AI system (instructions, examples, constraints, context) to produce reliable, accurate, useful outputs. Good prompts are specifications; great prompts are architectures.

Why it matters

The business case for Prompt Engineering.

The difference between a probabilistic model that fails in production and one that works often comes down to prompt engineering. It is the cheapest, fastest lever for improving AI output quality before retraining or architecture changes.
