The Power of Prompt Engineering: Exciting Use Cases for This Cutting-Edge AI Technique

Prompt Engineering Use Cases

Prompt engineering is one of the most exciting developments in AI right now. This technique allows us to fine-tune large language models like GPT-3 using carefully constructed prompts and instructions. The prompts “prime” the model to generate the desired output.

Prompt engineering unlocks a world of possibilities with large language models. By creatively crafting prompts, we can guide the models to perform remarkably well on tasks like summarization, question answering, classification, and even creative writing. Let’s explore some of the most promising prompt engineering use cases and see how this AI capability can transform industries.

Automated Customer Service Powered by Prompt Engineering

One of the most natural applications of prompt engineering is powering conversational AI chatbots for customer service. With the right prompts, we can get chatbots to understand customer issues, provide helpful information, and resolve complaints, all through natural conversation.

For example, suppose we want to build a customer support chatbot for an ecommerce company. The first step is “priming” the model to get into the customer service mindset using a prompt like:

“You are a helpful customer support agent for an online clothing store. Your goal is to understand customer issues and respond helpfully, politely and knowledgeably based on the company’s policies.”



We can then provide an example customer query, such as “Hi, I ordered a blue shirt last week and I still haven’t received it. Can you help track my order?”



The primed model can now generate a response roleplaying as the customer support agent, something like “Hello, thanks for getting in touch. Let me look into the status of your order. Could you confirm your order number and email address? I’ll be happy to provide an update once I check our systems.”



By crafting many prompts covering different scenarios, we can train the model to handle most common customer service conversations. The AI handles easy repetitive questions, freeing up human agents for more complex issues. Prompt engineering is revolutionizing customer service in this manner.

Automated Curation of Personalized News and Content

Media consumption habits are highly personalized today. Prompt engineering enables automated curation of customized news and content for each reader.

For instance, say we want to build an AI assistant that provides a daily personalized news digest for each user. The prompts can include the user’s interests and preferences to prime the model, such as:

“Curate a news digest for John who is interested in technology, business, football and likes to start his day on a positive note with inspiring news.”



The model can then scour various news sources and compile relevant headlines, summary blurbs, and recommended articles tailored specifically for John. By parameterizing the prompts for each user, this approach can automate personalized content curation at scale.

Major media outlets now use prompt engineering in this manner to increase reader engagement on their sites by recommending hyper-relevant content for each visitor. The applications for education, lifestyle services and other verticals are also immense.

Automated Data Analysis Powered by Prompts

Prompt engineering unlocks the ability for large language models to perform automated data analysis and generate insights just using natural language prompts.

For instance, say we have a large dataset on customer churn. Rather than code up complex scripts, we can simply prompt the model to analyze the data and identify key trends, something like:

“Please review this customer dataset and highlight the main factors that lead to churn. Present the analysis in a format suitable for an executive dashboard along with the top recommendations to reduce churn.”

The model can return neatly formatted outputs like:

Key Churn Factors

  • Customers with >10 complaints are 2x as likely to churn
  • Long-tenured customers (over 5 years) have lower churn


  • Identify and placate customers with >5 complaints
  • Provide loyalty bonuses for long-tenured customers

Such prompt-driven data analysis can make AI accessible to business users without coding skills. It also speeds up the machine learning workflow. Prompt engineering is revolutionizing how we build and use AI for business intelligence.

Prompts Can Code! Using AI for Software Development

Prompt engineering can guide large language models to generate computer code, opening up applications in software development.

For instance, we can give prompts like:

“Write a Python program that accepts a string input from a user and returns whether it is a palindrome or not.”

The model can then generate the complete code snippet:

def is_palindrome(input_string):
reversed_string = input_string[::-1]
if input_string == reversed_string:
return True
return False
user_input = input("Enter a string: ")

Developers can use prompts to generate boilerplate code, debug errors, and even develop new functionalities by simply describing them in plain English.

AI coding assistants based on prompt engineering can drastically speed up software development cycles and open up programming to non-developers. They might even detect vulnerabilities and bugs through prompts!

Automating Emails, Reports and Documents

Prompt engineering provides an easier way to automate document creation, from emails to reports and legal contracts.

For example, say we want to automate a weekly status report. We can give the model prompts describing the report sections and content formats. The AI assistant can then automatically pull data from various systems and compile the report in the desired structure.

Lawyers are using prompts to generate first drafts of contracts, reducing document creation time from hours to minutes! Marketers are automating personalized email campaigns at scale. Prompt engineering is revolutionizing document creation processes across many industries.

Prompting AI to Write Creative Fiction and Content

Perhaps one of the most surprising applications of prompt engineering is using AI for creative writing, including fiction stories, poems, lyrics, scripts, ideas for viral content and more!

For instance, primers like the one below can generate unique song lyrics:

“Write a catchy song verse about joy and celebration in an upbeat pop style. Use creativity, vivid imagery, and fun rhyming structure.”

By fine-tuning prompts, AI can produce novel content matching different genres, styles, topics, and formats. Brands now leverage this for marketing campaigns with videos, posts and ads created fully by AI! Writers use it to combat writer’s block. Prompt engineering is unlocking AI’s creative side.

The possibilities are endless as new use cases emerge every day across industries. But what makes prompt engineering tick? Let’s look under the hood to understand why it’s so powerful.

Why Prompt Engineering Works: Priming Models for Targeted Performance

Prompt engineering taps into the innate capabilities of large language models like GPT-3. Here are some key reasons why tailored prompts enable remarkable performance on a variety of tasks:

1. Activates Relevant Knowledge

The knowledge encoded in LLMs is vast but diffuse. Prompts focus the model on activating just the subset required for a given task. This context switching gets the model in the right headspace.

For example, a broad model may perform poorly on a medical question. But add the primer “You are an expert doctor assisting patients”, and its accuracy improves dramatically as the relevant medical knowledge gets activated.

2. Provides Examples as Training Signal

LLMs are trained by inferring patterns from vast volumes of text data. Providing example input-output pairs guides the model to generate similar responses.

For instance, when building an AI assistant, we can give this example prompt-response:

Human: Where can I get good tacos around here?

Bot: Taqueria El Rey on Mission St has excellent tacos with lots of great reviews! Let me know if you would like directions.

This signal trains the model on how to provide relevant recommendations.

3. Specifies Desired Response Format

Prompts can explicitly describe the required output structure, tone, length or style. This steering prevents meandering responses.

For example, when analyzing data we can request: “Summarize key trends in bullet points”. Without format specifications, models tend to respond in complex narratives.

4. Constraints Prevent Undesirable Outputs

Prompts can include constraints to limit off-topic or nonsensical tangents models are prone to wander into.

For instance, adding “without using any racist, unethical or dangerous language” ensures acceptable content. Constraints also boost computational efficiency by reducing false paths.

Through these mechanisms, prompt engineering channels the capabilities of huge models into targeted performance on specialized tasks.

Now that we’ve seen the immense potential of prompt engineering across industries, let’s look at some best practices to create effective prompts.

Crafting Excellent Prompts: Tips and Best Practices

The magic of prompt engineering lies in the details. Follow these tips to craft prompts that unlock the full potential of large language models:
