Practical prompt engineering is crucial for optimising the performance of ChatGPT, a large language model developed by OpenAI. We have been exploring this technology for the past few months and have already implemented it into our Dewalist Insight and Dewapost content creation for some blogs from content research, the outline, facts and sources, SEO meta description, SEO keywords, catchy title, tags, hashtags, co-author and co-editor.
“GPT-3 has 175 billion parameters, making it one of the largest AI models available.”— OpenAI
In this comprehensive tutorial, you will learn the basics of prompt engineering for ChatGPT, including designing effective prompts, addressing common issues, and refining prompts based on user feedback. This guide will also provide detailed examples to help you master prompt engineering techniques and improve the performance of your AI applications.
Please be aware that we’re not utilising the standard ChatGPT interface; instead, we’re using the OpenAI playground, which offers adjustable options.
A prompt is input from ChatGPT to elicit a specific response or action. In essence, it is the question, statement, or instruction provided to the AI to initiate a conversation or obtain a desired output.
To maximise the effectiveness of your prompts, it is crucial to understand the following components:
Context is the information surrounding the prompt that enables the AI to understand its meaning and provide a relevant response. To improve context, provide clear and concise information in the prompt or through additional context sentences. This can help guide the AI towards the desired output.
Poor context: “What is the capital?”
Good context: “What is the capital of Australia?”
Intent refers to the specific goal you want the AI to achieve with its response. Clarifying your intention when designing prompts is crucial, as ambiguous or poorly-worded questions may lead to irrelevant or unhelpful answers.
Ambiguous intent: “Tell me about snakes.”
Clear intent: “Describe the diet and habitat of brown snakes.”
Prompts can vary in length, but it is essential to balance providing enough information to guide the AI and avoiding overly long prompts that could confuse or overwhelm the model. ChatGPT has a token limit (2048 tokens for GPT-3), including input and output tokens.
Overly long prompt: “I’m interested in learning about the history of computers, specifically how they evolved from simple calculating devices into the complex machines we use today and the different types of computers that have been developed over the years, including mainframes, personal computers, and laptops.”
Balanced prompt: “Briefly explain the evolution of computers from simple calculating devices to modern machines and describe the main types of computers.”
Designing Effective Prompts
Clarity and Precision
An effective prompt is clear and precise in its intent. Ensure your prompt is specific enough to guide the AI towards the desired response. Avoid ambiguity, as it may lead to confusion and produce undesired outputs.
Ambiguous prompt: “Can you give me a recipe?”
Precise prompt: “Provide a recipe for homemade chocolate chip cookies.”
“The GPT-3 model has a token limit of 2048 tokens, which includes both input and output tokens.”— OpenAI
Breaking the prompt into step-by-step instructions for complex tasks may be beneficial. This can help guide the AI through the task and improve the quality of its output.
Single prompt: “Write an introductory paragraph for an essay about the benefits of exercise.”
- List three benefits of regular exercise.
- Write an introductory paragraph for an essay incorporating the listed benefits.
Open-Ended vs. Closed-Ended Prompts
Open-ended prompts encourage more creative and extensive responses, while closed-ended prompts typically generate shorter, more precise answers. Consider your goal when designing prompts and choose the appropriate type accordingly.
Open-ended prompt: “Describe the advantages and disadvantages of using solar energy.”
Closed-ended prompt: “Is solar energy a renewable resource?”
Common Issues and Solutions
Overly Verbose Responses
Problem: ChatGPT sometimes generates overly verbose or repetitive responses
Solution: Add explicit instructions to your prompt, such as “Please provide a concise response” or “Answer in one sentence.”
Original prompt: “What are the benefits of exercise?”
Improved prompt: “List three benefits of regular exercise in one sentence.”
Problem: Ambiguous prompts can lead to irrelevant or unclear responses.
Solution: Make the prompt more specific and clear. Reframe the question or instruction to provide context and focus on the desired outcome.
Ambiguous prompt: “Tell me about plants.”
Improved prompt: “Explain the process of photosynthesis in plants.”
Problem: ChatGPT may sometimes provide off-topic or unrelated responses.
Solution: Modify the prompt to be more specific or include additional context. Alternatively, you can use step-by-step instructions to guide the AI through the task.
Off-topic prompt: “Tell me about blockchain.”
Improved prompt: “Discuss the impact of cryptocurrency on the finance industry.”
Techniques for Improving ChatGPT Responses
Temperature is a parameter that controls the randomness of the AI’s output. A higher temperature (e.g., 0.8) will produce more diverse and creative responses, while a lower temperature (e.g., 0.3) will result in more focused and deterministic outputs. Experiment with different temperature settings to find the ideal balance for your application.
High temperature (0.8): “The capybara, a large, rotund rodent, reigns as the aquatic king of the animal kingdom, leisurely lounging by rivers and lakes, nibbling on grass and basking in the sun.”
Low temperature (0.3): “The capybara is the largest rodent in the world and is commonly found near bodies of water in South America.”
“In 2021, OpenAI released ChatGPT Plus, a subscription plan that offers premium features, faster response times, and priority access to new features and improvements.”— OpenAI
Setting a max token limit can help control the length of the AI’s response. By specifying a limit, you can ensure the output is concise and adheres to your desired length. However, be cautious about setting the limit reasonably, as this may result in incomplete or nonsensical responses.
Original prompt: “Explain the process of photosynthesis.”
Max tokens set to 5: “Photosynthesis is a process where”
Max tokens set to 50: “Photosynthesis is a process where plants convert sunlight, water, and carbon dioxide into oxygen and glucose. This process occurs in the chloroplasts, which contain the green pigment chlorophyll. During Photosynthesis, the energy from sunlight is used to split water molecules into hydrogen and oxygen.”
Prompt chains involve breaking down a complex task into smaller, more manageable prompts. By sequentially providing these prompts to ChatGPT, you can guide the AI through the process more effectively. This can be particularly useful for multi-step tasks or requiring the AI to maintain context across multiple inputs and outputs.
Complex task: “Write a brief analysis of the poem ‘The Road Not Taken’ by Robert Frost.”
- “Summarise the poem ‘The Road Not Taken’ by Robert Frost.”
- “Identify the main theme of ‘The Road Not Taken’ by Robert Frost.”
- “Discuss the poet’s use of imagery and symbolism in ‘The Road Not Taken.'”
Iterative Prompt Refinement
Iterative prompt refinement is improving your prompts based on the AI’s responses. Analysing the outputs and refining your prompts can enhance the AI’s understanding and performance.
Test and Iterate
Testing prompts with ChatGPT and assessing the results is important when designing prompts. Then, based on the AI’s responses, identify potential issues and refine your prompts to improve their effectiveness.
Initial prompt: “Discuss the importance of staying hydrated.”
AI response: “Staying hydrated is essential for overall health and well-being. Water is a vital component of the human body, accounting for approximately 60% of body weight. It helps regulate body temperature, transport nutrients, and remove waste products. Additionally, staying hydrated can improve cognitive function, prevent fatigue, and reduce the risk of certain health conditions.”
Refined prompt: “Discuss the importance of staying hydrated for athletes and the potential consequences of dehydration during physical activity.”
Incorporate User Feedback
Collecting user feedback is an invaluable resource for prompt engineering. By understanding how users interact with ChatGPT and identifying areas of confusion or dissatisfaction, you can refine your prompts to suit their needs better.
User feedback: “The AI’s response was too general. I was looking for specific tips on how to stay hydrated.”
Refined prompt: “Provide five practical tips for maintaining proper hydration throughout the day.”
Mastering prompt engineering is essential for optimising the performance of ChatGPT and ensuring a positive user experience. By following the principles and examples outlined in this tutorial, you can design effective prompts, address common issues, and improve the overall effectiveness of your AI applications. Remember to test and iterate on your prompts, using user feedback to guide your refinements. With practice and persistence, you’ll be well-equipped to excel in prompt engineering for ChatGPT.
