Section 2

  • The persona pattern in prompt engineering involves crafting prompts or stimuli based on hypothetical personas for the AI or the user. A persona is a fictional representation of a typical user or target audience member based on user research—the systematic study of user needs, behaviors, and preferences. By incorporating characteristics such as age, occupation, preferences, and goals, AI responses become significantly more relevant and context-aware.
