Prompt Engineering

Designing and refining model inputs to reliably elicit accurate, useful and safe outputs.

Definition

Prompt engineering covers clear instructions, context, examples, output format specifications, role assignment and task decomposition. It is iterative and should be measured against evaluations. It is usually the first and cheapest way to improve a generative AI application.

Exam tip

Try prompt engineering before RAG or fine-tuning; it is the lowest-cost customization.
