Prompt Engineering
Prompt engineering is the practice of designing and refining text inputs to elicit accurate, relevant, and well-structured outputs from a language model. It involves choosing wording, format, examples, constraints, and ordering of instructions. Practitioners iterate on prompts using evaluation sets, measuring changes in correctness, style, and reliability across the model's expected range of inputs.
Definition
Prompt engineering is the practice of designing and refining text inputs to elicit accurate, relevant, and well-structured outputs from a language model. It involves choosing wording, format, examples, constraints, and ordering of instructions. Practitioners iterate on prompts using evaluation sets, measuring changes in correctness, style, and reliability across the model's expected range of inputs.
Examples
- Adding 'Respond only in valid JSON' to enforce a parseable output schema.
- Reordering instructions so constraints appear before the user question.
- Replacing 'summarize this' with 'summarize in three bullets under 20 words each'.
