4. Best Practices for Prompt Writing
Effective prompt writing requires precision, clarity, and an understanding of the desired outcome. This lesson will explore the best practices for crafting prompts that guide AI models toward producing relevant and high-quality responses.
Lesson 1: Start with Clear and Specific Instructions
1.1 The Importance of Specificity
To ensure a high-quality response, prompts should always be clear and specific. Vague or unclear instructions can lead to incomplete or irrelevant results.
Example of a Vague Prompt:
Explain how machines work.- Problem: The prompt is too general—what type of machines, in what context?
Improved Version:
Explain how electric engines in cars work, focusing on their energy efficiency compared to gasoline engines.- Improvement: Specifies the type of machine (electric engines in cars) and the comparison (energy efficiency vs. gasoline engines).
1.2 Flow of Specificity

A[Specific Prompt] --> B[Clear Objective];
B --> C[Focused Response];
C --> D[Better User Satisfaction];1.3 Key Takeaway
- Always define the context, subject, or task clearly.
- Specify subtopics, examples, or formats if needed.
Lesson 2: Break Down Complex Prompts
2.1 Simplify Large Tasks
Prompts that are too complex can overwhelm the AI, causing fragmented or unfocused responses. Breaking down complex tasks into smaller, digestible pieces makes the prompt easier to follow.
Example of an Overly Complex Prompt:
Write an essay about the history of artificial intelligence, its current applications in healthcare, and future possibilities in transportation, all within 500 words.- Problem: The scope of the prompt is too large, making it difficult to generate a cohesive response.
Improved Version:
1. Write a 300-word summary of the history of artificial intelligence.
2. Explain two current applications of AI in healthcare in 200 words.
3. Discuss potential future uses of AI in transportation in 200 words.- Improvement: Breaks down the task into separate, focused prompts, allowing for deeper exploration of each topic.
2.2 How to Structure Complex Prompts
- Identify Key Components: Split tasks based on topic, depth, or format.
- Set Clear Boundaries: Define what each part of the task should address.

A[Overly Complex Task] --> B[Split into Subtasks];
B --> C[Clear and Focused Response];Lesson 3: Provide Context
3.1 Why Context Matters
Providing the AI with background information or contextual clues can guide it toward producing a more accurate response. Context helps the model understand the broader picture.
Example of a Context-Lacking Prompt:
Explain climate change.- Problem: Without context, the response may focus on any aspect of climate change (scientific, political, societal) or even offer too broad a perspective.
Improved Version with Context:
Explain how climate change is affecting agriculture in developing countries.- Improvement: Narrowing the focus to agriculture and developing countries gives the model a clear framework for its response.
3.2 Contextual Clarity
- Use Real-Life Examples: Tie the prompt to a real-world scenario.
- Relate to a Specific Field: Define the subject’s relevance in a particular context (e.g., agriculture, education, industry).
graph TD;
A[Context-Lacking Prompt] --> B[General Response];
A --> C[Contextual Prompt];
C --> D[Specific Response];Lesson 4: Include Constraints
4.1 The Power of Constraints
Constraints, such as word limits, tone, or style, help define the scope of the response. Without constraints, the AI may generate content that’s too lengthy or too short, or may veer off-topic.
Example Without Constraints:
Write a summary of quantum computing.- Problem: The model could generate a response that is too long, too short, or focused on aspects irrelevant to your needs.
Improved Version with Constraints:
Write a 150-word summary of quantum computing, focusing on how it differs from classical computing.- Improvement: Specifies the length and focus, ensuring a concise and targeted response.
4.2 Types of Constraints
- Length: Word count or character limits.
- Tone: Formal, casual, technical, etc.
- Focus: Specific subtopics or questions.
graph TD;
A[Unconstrained Prompt] --> B[Unfocused Response];
A --> C[Constrained Prompt];
C --> D[Focused and Relevant Response];4.3 Example Code: Using Constraints in AI Prompts
Here’s a Python code snippet to show how to impose constraints using OpenAI’s API:
import openai
def generate_response(prompt, max_tokens=100, temperature=0.7):
response = openai.Completion.create(
engine="text-davinci-003",
prompt=prompt,
max_tokens=max_tokens, # Sets the word/length constraint
temperature=temperature # Controls creativity
)
return response.choices[0].text.strip()
prompt_text = "Write a 100-word summary on the advantages of solar energy."
response = generate_response(prompt_text, max_tokens=100)
print(response)4.4 Key Takeaway
- Constraints refine and focus the AI's output, ensuring relevance and precision.
Lesson 5: Tailor Prompts to the Audience
5.1 Understanding Audience Needs
Different audiences have different expectations and knowledge levels. Tailoring your prompt to suit the audience ensures that the response is both understandable and relevant.
Example of a Mismatched Prompt:
Explain blockchain technology in detail.- Problem: If the audience is beginners, this could result in an overly technical response that is hard to follow.
Improved Version for Beginners:
Explain the basics of blockchain technology for someone without any background in computer science.- Improvement: Simplifies the explanation for a general audience without technical knowledge.
5.2 Tailoring Prompts Based on Audience:
- Beginner: Use simple language and avoid jargon.
- Prompt: "Explain what artificial intelligence is in simple terms."
- Intermediate: Use some technical language but provide explanations.
- Prompt: "Explain how neural networks work with an example of their use in image recognition."
- Expert: Use industry-specific terms and advanced concepts.
- Prompt: "Discuss the advancements in reinforcement learning algorithms for autonomous vehicles."
graph TD;
A[Know the Audience] --> B[Beginner-Friendly Language];
A --> C[Intermediate-Level Detail];
A --> D[Expert-Level Insight];5.3 Key Takeaway
- Match the complexity and style of the prompt with the audience’s knowledge level to ensure clarity and engagement.
Lesson 6: Iterate and Improve Prompts
6.1 Iteration is Key
Prompt writing is an iterative process. Testing, refining, and improving prompts over time ensures better and more consistent responses. Continuously adjust prompts based on results and feedback.
6.2 Example: Improving a Prompt Through Iteration
Initial Prompt:
Explain the uses of machine learning.- Issue: The response might be too broad or lack focus.
First Revision:
Explain the uses of machine learning in healthcare, with examples of current applications.- Improvement: Narrows the scope to healthcare and asks for examples.
Final Version:
Explain how machine learning is used to improve diagnostics in healthcare, providing two specific examples of its application in modern hospitals.- Further Refinement: Adds more specific instructions, leading to a focused and detailed response.
6.3 How to Iterate on Prompts:
- Test the Prompt: Analyze the output and identify areas of improvement.
- Adjust and Refine: Add more specificity, context, or constraints.
- Retest: Evaluate how the changes affect the outcome.
graph TD;
A[Test the Prompt] --> B[Analyze Response];
B --> C[Identify Weaknesses];
C --> D[Revise the Prompt];
D --> E[Test Again];Conclusion
Writing effective prompts is both an art and a science. By following best practices—providing clear instructions, breaking down complex tasks, offering context, adding constraints, tailoring to the audience, and iterating over time—you can craft prompts that yield accurate, relevant, and valuable responses.
