Prompt Engineering for GPT-5

Aug 25, 2025

Overview

This lecture introduces prompt engineering for GPT-5, emphasizing a seven-step prompt structure to improve results and efficiency with AI tools.

Importance of Prompt Engineering

  • Prompt engineering is a vital skill in daily AI use, especially with new models like GPT-5.
  • GPT-5 delivers best results when given clear, structured, and explicit prompts.

The Seven-Step Prompt Structure

  • Role: Define the persona or expertise GPT-5 should adopt (e.g., travel expert, marketing strategist).
  • Task: Clearly state the specific task you want GPT-5 to perform.
  • Context: Provide background info, target audience, relevant documents, or constraints GPT-5 should consider.
  • Reasoning: Specify approaches, logic, or steps GPT-5 should use to address your query.
  • Rules: List any non-negotiable constraints or requirements (e.g., only vegetarian options).
  • Stop Condition: Indicate when GPT-5 should stop generating output (e.g., after a set number of examples).
  • Output Format: Describe the desired output format (e.g., table, bulleted list, Markdown).

Example Applications

  • Structured prompts for creating a 30-day marketing plan include detailed role, task, context, reasoning, rules, stop conditions, and output format.
  • Travel itinerary example: Role as travel guide, task for a vegetarian-friendly trip, context about interests and timeframe, rules about food and walking distance, stop after 5 days, output in a bulleted itinerary with restaurants in italics.
