The Power of Prompt Engineering
Introduction:?
Prompt engineering has emerged as a pivotal technique in leveraging the capabilities of modern language models, allowing users to interact more effectively and obtain desired outputs. While many people are aware of ChatGPT and other LLM chat interfaces, most leverage them using simple question answer type prompts, not really understanding some of the true power that LLMs can provide.
In this article, we will delve into the concept of prompt engineering, explore the differences between one-shot and few-shot prompts, discuss user versus system instructions, introduce the Role, Action, Steps, Context, Examples (RASCE) framework for constructing effective prompts and illustrate the impact pf leveraging these techniques on output generation using a practical example.
What is Prompt Engineering??
Prompt engineering refers to the process of designing input instructions or queries that guide language models in generating desired outputs. It involves formulating precise and structured prompts that elicit the desired information or responses from the model. Effective prompt engineering enables users to harness the power of language models and achieve more accurate and tailored results.
One Shot vs Few Shot Prompts:?
One Shot Prompts:?
One shot prompts provide a single input instruction or query to the language model, expecting it to generate the desired output. These prompts are suitable when the task at hand requires a straightforward response and the desired output can be generated with minimal context or additional information.
Few Shot Prompts:?
Few shot prompts involve providing multiple examples or demonstrations of the desired output to the language model. By exposing the model to a few instances of the desired behavior, it can generalize and adapt to generate accurate responses even for complex tasks or nuanced requirements. Few shot prompts enhance the model's ability to understand and learn from a wider range of inputs.
Demonstrating One Shot vs Few Shot:?
To illustrate the impact of one shot vs few shot prompts, let's consider a hypothetical scenario: creating a personalized recipe recommendation system.
One Shot Prompt: "Generate a recipe for a vegetarian pasta dish."
Few Shot Prompt: "Generate two recipes for vegetarian pasta dishes: 1) A creamy pesto pasta with roasted vegetables and 2) A spicy arrabbiata pasta with tofu
By providing a few shot prompt with specific examples, the model gains a better understanding of the desired output and can generate recipes that align with the given context. This enables the system to generate more accurate and tailored recommendations compared to a single one shot prompt.
User vs System Instructions:
Prompt engineering involves defining both the user instructions and system instructions to guide the language model effectively.
User Instructions:?
User instructions convey the desired information or input the user wants to obtain from the language model. They specify the nature of the task or the information sought. For example, "What are the main causes of climate change?" or "Summarize the plot of the novel 'Pride and Prejudice.'"
System Instructions:?
On the other hand, system instructions describe how the desired output or response should be generated by the language model. They provide guidance to the model on how to structure the output or the format in which the information should be presented. For instance, "Provide a detailed explanation with key points" or "Present the summary in bullet points."
The user instructions focus on the input, conveying the user's intent or the information they seek, while the system instructions focus on the output, providing guidance on how the desired output should be generated or presented.
By effectively leveraging System Instructions, Language Models can be much more powerful in assisting in tasks. One of my "go to" System Instructions working in Operations is to tell the LLM to provide an output in CSV or JSON format. Being able to have the flexibility to specify formats just through adjusting prompts is very powerful.
By carefully crafting both user and system instructions, prompt engineering enables users to effectively communicate their intent and expectations to the language model, resulting in more accurate and tailored responses.
The RASCE Framework for Constructing Prompts:?
To construct effective prompts, the RASCE framework can be employed:
By following the RASCE framework, prompts can be constructed in a structured and comprehensive manner, enabling more effective communication with the language model.
Putting it all Together
Let's return back to the previous example of the vegetarian pasta recipes to demonstrate all of the concepts discussed in this article in a single prompt.? I like this example because I think it illustrates really well not only the content returned, but also the flexibility in driving the format.
_________________________________________________________
Role: Recipe generator
Action: Generate two vegetarian pasta recipes
Steps:
Context: Emphasize the use of common ingredients and easy preparation methods
Examples: Specify two recipes - creamy pesto pasta with roasted vegetables, and lemon-garlic linguine with sun-dried tomatoes
System Instructions: "Do not use the Example recipes, but instead choose two unique recipes. Present the recipes in Markdown format, ensuring that each recipe includes the following sections: Ingredients, Instructions, and Notes. Use bullet points for the ingredients and numbered lists for the instructions. Provide a brief introduction for each dish."
_____________________________________________________________
And below are the results! It's important to note that I simply copied and pasted the output from ChatGPT, all of the formatting was done by ChatGPT based on the System Instructions that were provided.? If you want to see it for yourself simply copy and paste the above prompt into ChatGPT and check out the results.

Prompts For an Operations Use Case
Here is one final example that is more relevant to how someone in Sales Operations would want output. Leveraging an API to an LLM will allow you to take the result set and take further programatic action on it.

Role: You are a data analyst
Action: Research the top 10 towns in Morris County New Jersey in terms of population
Steps:
1. Provide the list in table format
2. The table should have the following columns: Town, County, State, Population
System Instructions: You should only respond with CSV Output. No other commentary or output should be provided.

1 年Interesting article! I appreciate how you demonstrated how to apply this framework of thinking with an example. I had never heard of RASCE before but like its systematic approach to prompt writing. I think you may even be able to utilize this approach when communicating and collaborating with other humans. Will be incorporating these pasta recipes into next weeks grocery list!
Nice read Glenn!
