Prompt Engineering Quick Start All-in-One

Prompt Engineering refers to designing and optimizing input prompts to maximize the capabilities of AI models. For beginners, mastering this skill can improve interaction efficiency with AI and enhance understanding of how AI works. This article demonstrates how to craft effective prompts through examples.

1. What is a Prompt?

When using AI models, the text input by the user is called a "prompt." It guides the AI to generate corresponding outputs. Well-designed prompts can help AI models provide more accurate and relevant responses.

2. Why is Prompt Engineering Important?

1. Improves the accuracy of model outputs: A well-thought-out prompt reduces bias in outputs.
2. Enhances user experience: Better prompts make AI interactions more natural and efficient.
3. Broad applications: From text generation to image recognition, prompt engineering plays a vital role.

Let’s start with an example that employs multiple prompt techniques:

Task: Write an article discussing the causes of climate change, its impact on the global economy, and possible solutions.

Prompt: The annotations on the right indicate the techniques used in this prompt.

Write an article about climate change. ← Clear and concise
Divide the article into three sections: causes of climate change, its impact on the global economy, and possible solutions. ← Provide context

Each section should be marked with a heading and contain at least two paragraphs. ← Specify format and structure

Include at least one real-world example in each section. ← Use examples

First, list the main causes of climate change; then analyze how these causes affect the global economy; finally, provide three solutions. ← Incremental refinement

Clearly explain that "climate change" refers to anthropogenic global warming rather than natural climate variations. ← Avoid ambiguity

Each paragraph should be no longer than 200 words for readability. ← Specify clear formatting requirements

The total article length should be between 600 and 800 words. ← Set limits and conditions

Start from basic concepts and gradually delve into complex economic impacts and solutions. ← Use step-by-step reasoning

Avoid common misconceptions, such as the idea that climate change only affects certain regions rather than the entire globe. ← Use counterexamples

Assume current policies and technological levels remain unchanged, and analyze possible trends over the next 10 years. ← State assumptions or premises

The article should adopt an academic and formal tone. ← Specify style or tone

Play the role of an environmental economist and provide professional insights and recommendations. ← Role-playing

After each section, include supplementary explanations and examples to deepen reader understanding. ← Use iterative interactions

The above example demonstrates some basic principles and techniques for crafting prompts. Let’s delve into the details:

3. Basic Principles

3.1 Clear and Concise

• Explicit instructions: Ensure that the desired output is clearly stated.
  Example:
  Poor: “Tell me something about cats.”
  Better: “List five interesting facts about cats.”

3.2 Provide Context

• Add background information: Provide sufficient information to help AI understand the task's context.
  Example:
  Poor: “Write a story about it.”
  Better: “Write a story about a lost cat finding its way home.”

3.3 Specify Format and Structure

• Indicate output structure: If a specific format is needed, mention it explicitly in the prompt.
  Example:
  Poor: “Give me a shopping list.”
  Better: “Provide a bulleted shopping list that includes milk, bread, and eggs.”

4. Prompt Techniques Examples

4.1 Use Examples

Provide concrete examples to help AI understand your desired format and content.

• Example:
  “Translate the following sentence: ‘The cat is sleeping.’”
  Reinforce understanding by repeatedly asking for similar translations.

4.2 Incremental Refinement

Start with simple tasks and gradually increase complexity. This method helps AI adapt better to task requirements.

• Example:
  Start: “List five characteristics of cats.”
  Then: “Based on these characteristics, write a description.”

4.3 Avoid Ambiguity

Avoid using language that might lead to misunderstanding or multiple interpretations. Ensure clarity in instructions.

• Example:
  Poor: “Write an article about banks.”
  Better: “Write an article about how financial institutions influence the economy.”

4.4 Specify Clear Formatting Requirements

If you need a specific output format, clearly state it in the prompt.

• Example:
  “Provide a bulleted shopping list that includes milk, bread, and eggs.”

4.5 Set Limits and Conditions

If certain conditions or restrictions are critical to the task, clearly specify them.

• Example:
  “Summarize the key points of this article in under 200 words.”

4.6 Use Step-by-Step Reasoning

Guide the AI to reason and solve problems step by step, especially for complex tasks.

• Example:
  “First, list all relevant factors, then analyze the relationships between them.”

4.7 Use Counterexamples

Help the AI understand what is not desired by providing counterexamples.

• Example:
  “Avoid mistakes like: ‘Cats are a type of plant.’”

4.8 State Assumptions or Premises

If the task depends on specific assumptions, clearly state them in the prompt.

• Example:
  “Assume cats can talk. Describe a day in their life.”

4.9 Specify Style or Tone

If the output requires a specific style or tone, indicate it in the prompt.

• Example:
  “Rewrite the following sentence in a humorous tone: ‘The meeting was surprisingly productive.’”

4.10 Use Iterative Interactions

Guide the AI step by step through multiple rounds of dialogue to produce outputs that better meet your requirements.

• Example:
  Round 1: Ask for basic information about cats.
  Round 2: Request a detailed description.

By using these techniques, you can design prompts more effectively, interact with AI more precisely, and achieve more satisfactory results.

• Provide examples to guide the AI: Use examples to demonstrate the desired output format and content.
  Example:
  “Translate the following sentence: ‘The cat is sleeping.’”
  Afterward, provide similar translation requests repeatedly to reinforce the model's understanding.

Guide the AI progressively to generate content that better meets requirements through multiple rounds of interaction.

4.11 Role-Playing

Clearly instruct the AI to play a specific role to receive more personalized and contextually appropriate responses.

• Set a Role: Specify the role the AI plays during the conversation to ensure output aligns with character traits.
  Example: “You are a seasoned historian. Explain the impact of the Age of Exploration.”
• Simulate Dialogues: Use role-playing for dialogue simulations, suitable for training and educational scenarios.
  Example: “You are a customer service representative. Assist a customer with product inquiries.”
• Recreate Scenarios: Place the AI in specific contexts to provide empathetic responses.
  Example: “You are a counselor. How would you comfort a stressed student?”
• Specify Tone and Style: Adjust the AI's tone and style based on the role.
  Example: “As a storyteller for children, narrate a tale about friendship in a warm and imaginative tone.”
• Simulate Historical Figures: Let the AI embody historical figures to respond in the first person.
  Example: “You are Einstein. Explain the core concept of relativity.”

Benefits of Role-Playing

• Rich Interaction Experience: Role-playing provides more vivid and engaging interactions.
• Enhanced Creativity: Explore different perspectives and problem-solving methods through role-playing.
• Contextual Adaptability: Tailor AI to specific contexts for more relevant suggestions and solutions.

Role-playing allows AI to engage in more specific contexts and tones, facilitating personalized and emotionally resonant communication.

5. Practical Applications

5.2 Data Extraction

Objective: Extract key information from a text.
Prompt Example:
“From the following text, extract all mentioned dates and events: ‘The meeting is scheduled for October 12, 2023, and the report deadline is December 1 of the same year.’”

5.3 Translation and Rewriting

Objective: Translate text into another language or rewrite it in a different style.
Prompt Example:
“Translate the following sentence into French: ‘The weather today is sunny and warm.’”
“Rewrite the following sentence in a humorous tone: ‘The meeting was surprisingly productive.’”
