The roots of prompt engineering in AI extend back to the early stages of artificial intelligence research. In the 1950s and 1960s, trailblazers John McCarthy and Marvin Minsky explored employing computers to simulate human intelligence. 

As the AI industry developed more and more, the focus switched towards creating systems capable of executing specific tasks, ranging from playing chess to natural language understanding and processing (NLP).

The resurgence of interest in AI during the 1980s and 1990s was propelled by the increasing computational power of computers and the availability of novel datasets. Researchers delved into pioneering techniques such as neural networks and genetic algorithms, strategies that continue to wield considerable influence in modern AI/ML development approaches.

The 1990s till the early 2000s was mostly covered by neural network development and pre-transformers. And, only from 2018 we have started to see significant growth of NLP, transformer models, and machine learning.

As of early 2024, prompt engineering is undergoing its evolution, mirroring the dynamic Generative AI field and its various applications. Recent breakthroughs have notably shaped how we engage with AI models, especially with a particular impact on Large Language Models (LLMs).

What is Reverse Prompt Engineering

We have already learned some great historical facts about Prompt Engineering and its origin. However, ChatGPT developers and AI Chatbot engineers have already researched many important points in Reverse Prompt Engineering for the last couple of years. Let’s try to figure out what it means and how it can be used.

The basic concept of Reverse Prompt Engineering (RPE) has appeared as a sophisticated technique, imparting a noteworthy level of precision to AI implementation or ChatGPT integration. Talking about reverse engineering for beginners, we may imagine this as an approach that harnesses the generative capacities of Large Language Models (LLMs) to create effective prompts. The general process of RPE involves furnishing the LLM with the intended output and tasking AI with generating the optimal prompt capable of yielding such a desired result. 

To keep it simple, imagine that your company brand name was created using OpenAI ChatGPT and you need to understand how the model was instructed and what prompt was used for this. In some way, it is a kind of journey to the past or reverse.

This innovative strategy not only taps into the prowess of LLMs but also streamlines the interaction between users and AI systems, offering a new way to tailor inputs for desired outcomes. By leveraging the inherent creativity and language understanding of these models, Reverse Prompt Engineering has the potential to enhance the efficacy and power of Conversational AI, contributing to a more refined and tailored user experience.

Types of Reverse Prompt Engineering

Micro and Macro: we all have already heard these words millions of times. How can we apply them to the RPE? The point is that Reverse Engineering coding of prompts can be divided into two categories (Haptik):

  • Micro Reverse Prompt Engineering or MiRPE
  • Macro Reverse Prompt Engineering or MaRPE

Both categories are suitable for custom AI development needs and fine-tuning of Large Language Models too. Let’s take a look at them in detail.

Micro Reverse Prompt Engineering

MiRPE approach includes a closer examination of the engineered prompt, honing in on special keywords essential to the task at hand. In other words, in this type of Reverse Prompt Engineering we are asking AI for its help in figuring out the necessary keywords we should use to ensure the prompt we want to create is absolutely clear for the model. So, this is like getting extra help for a more accurate result we want to achieve.

Macro Reverse Prompt Engineering

On the other hand, within the MiRPE method, the initial step entails presenting the model with either the needed output or a particular scenario. Thus, the model is directed to generate a prompt that can effectively reproduce the needed output or adeptly show the given scenario.

It is worth noting that Macro RPE may also be divided into categories such as:

  • Scenario-Based Prompt Engineering
  • Example-Based Prompt Engineering

Scenario-based MaRPE takes a systematic and interactive approach, involving the presentation of a designated "Scenario" to the model. In this way, the model is prompted to generate a needed prompt coded to address the specified scenario.

The other type - example-based Reverse Prompt Engineering - represents a unique method that allows creating a prompt template by analyzing already existing examples of a needed output and then using this template to generate pretty similar results.

The Step-by-Step Process of Reverse Prompt Engineering

So, we have already discovered the understanding of reverse engineering for beginners and its types. Let’s move on to the more hard part - the process of Reverse Prompt Engineering and reverse prompt coding.

The process of RPE can be divided into such stages (EcoAgi):

  1. Model Initiation
  2. Data Selection
  3. Reverse Prompt Generation
  4. Rewriting of Reverse Prompt
  5. Reverse Prompt Testing and Iteration

Model Initiation

The initial phase of effective reverse prompt engineering focuses on priming the model. This entails furnishing the model with a sequence of input text, enabling it to grasp the context of the engineering task at hand. To initiate this process, instruct the model (let’s say we use ChatGPT) with a statement such as: "I want to employ reverse prompt engineering, looking for your assistance in generating prompts based on the provided text for optimal and ideal content replication." This step initiates the model.

Data Selection

The next step is to choose the text or code that you need to apply reverse engineering coding to. This kind of selection could range from a blog post like "What is content marketing" to a part of code. The important aspect is to opt for a text that aligns with the nature of the content you aim to produce. As soon as you select, proceed to copy and paste the chosen text into the same ChatGPT box taken from the model initiation in the earlier step.

Reverse Prompt Generation

As soon as the model is primed and has the starting text, it's time to generate the reverse prompt. And here is the place where the Generative AI magic happens. When you hit the button, ChatGPT will return a prompt that provides a general structure of the prompt and should be used as a reference when rewriting the reverse prompt.

Rewriting of Reverse Prompt

For using reverse prompt in more specific contexts, it should be rewritten to be more general. For example, if the generated prompt is:

"Write a sentence about going to the store and buying something"

You could rewrite it to be:

"Write a sentence about [input field: action] and [input field: result]"

It helps the prompt to be more applicable to a wider range of scenarios. The final prompt should look something like this:

"Write a sentence about [input field: action] and [input field: result]. The tone should be [input field: tone] and the writing style should be [input field: writing style]."

Finally, all these give you a flexible template that you can use to generate a variety of content.

Reverse Prompt Testing

As soon as our prompt has been rewritten, we need to test it. So, we need to copy the prompt and then open a new ChatGPT model or other LLM model if we use it for sure. Then, we have to paste the prompt into the empty ChatGPT model and input the tone and writing style that we want to use.

Right after all we have to do is to submit the button and we will see a generated sentence based on the prompt. This step is crucial as it allows us to see the effectiveness of reverse engineered prompt in action. 

If the generated sentence is not exactly what we need, it’s time to iterate and adjust the prompt. So, we need to copy the prompt, head back to the ChatGPT model, and then edit accordingly. When the prompt is edited, we need again to paste it into the ChatGPT model and hit submit. This iterative process is key to refining reverse-engineered prompts and ensuring they produce the desired results.

How To Apply Reverse Engineering Process

Congratulations! Now, as we have already learned the process and steps of Reverse Engineering, we moved from reverse engineering for beginners to reverse engineering coding experts. RPE can be applied in various scenarios, from generating blog posts to creating code snippets. Let’s try to find out how to apply Reverse Prompt Engineering nowadays.

  • Branding. In marketing or sales, reverse prompt engineering proves valuable for product description generation or branding activities. By reverse engineering prompts from well-written product descriptions, similar descriptions can be generated.
  • Blog Posts. For bloggers and content creators, reverse prompt engineering offers a transformative approach. By reverse engineering prompts from well-crafted blog posts, similar content can be generated.

Have a question?

Overall, Reverse Prompt Engineering can be applied in many different cases and industries. Feel free to test it yourself or find out more with our AI experts.

Tools for Reverse Prompt Engineering

It is worth saying that Reverse Prompt Engineering is quite a new approach in Prompt Engineering itself and currently, there are almost no specific products on the market that are used for reverse engineering of prompts or reverse engineering coding.

The one tool that kept our attention is FlowGPT- a tool for “empowering every prompter to learn and build their own AI and showcase them to the world”, as their slogan states.

The tool has a feature with RPE that allows the user to have a generated prompt after submitting the needed output. Have a look at the screenshot from that tool:

We have made several tests but the results were not as we expected so it is up to you to test it yourself and make sure it is suitable for your case.

So, what is recommended for now is using already well-known web interfaces integrated with famous open-source or closed-source Large Language Models:

You may use any other model for sure and play around with reverse prompt engineering using such a model. Just make sure it suits your requirements and the results you expect to achieve.

Examples of Reverse Prompt Engineering

The best way to see how prompt reverse engineering works is to have a look at some examples. We have already talked about how we may divide RPE into macro and micro, so let’s see how it works in these cases.

Example #1

Imagine we are a Digital Marketing Agency that needs to generate a tagline and we admire the famous MasterCard tagline: “There are some things money can’t buy. For everything else, there’s MasterCard”. So, we want to write a prompt that can help generate a similar tagline. Let’s test it with ChatGPT.

The steps we need to take are as follows:

  1. Explain the task to the model. Firstly, we need to tell our LLM that we need its assistance in analyzing a provided tagline and summarizing its core message to turn it into a prompt.
  1. Clarify the task if needed (additionally). If the model asks for any clarifying questions, please answer them. In our case, ChatGPT seems to understand the task well.
  2. Provide the sample. So, in this step, we have to share the MasterCard tagline we admire.
  1. Transform the generated prompt into a prompt template. With the prompt created, instruct the model to transform this prompt into a reusable template.

That’s it! As far as the prompt template created might not be perfect, but it offers a huge background that can be easily refined and repurposed. You may also try it with any other AI Chtabots and see how it works!

Example #2

We have talked earlier about keyword-based options to work with reverse prompt engineering. Let's see now how it can be implemented in practice.

  1. Looking for guidance on the proper keyword. Instead of overwhelming the LLM with the entire task, we start by asking for guidance on the technical terms for the process we need.
  1. Clear Prompt Creation. Now that we know “Paraphrasing” or “Data Augmentation” is the right keyword for our task, our next step is to generate a prompt that precisely guides the model. So we can use prompts like:

Please generate accurate paraphrases

of the following user utterance...


Imagine you are the Data Augmentation system.

Given a user input like…

Therefore, by concentrating on keywords and expected guidance rather than generating entire prompts, this approach effectively prevents the LLMs from being inundated. It progressively seeks the LLM's assistance in small increments, facilitating the construction of precise prompts in a more easily manageable manner.

Reverse Prompt Engineering Use Cases

Reverse prompt engineering, also known as prompt hacking, prompt design or reverse engineering coding, involves creating different prompts to generate specific responses from a language model. Let’s have a look at the most popular use cases for reverse prompt engineering:

Sales & Marketing

  • Generate creative marketing and sales prompts to elicit imaginative and unique stories or ideas from the required Large Language Model.
  • Craft prompts for generating taglines, slogans, messages, posts, and many other valuable content.


  • Create prompts to extract educational information and explanations on various topics.
  • Develop questions that prompt detailed and comprehensive answers for study materials.

Software Development

  • Design prompts to look for needed code snippets, explanations, or solutions for programming-related queries.
  • Generate prompts for debugging assistance or to understand specific coding concepts.


  • Create prompts to obtain translations for specific phrases or sentences in different languages.
  • Generate queries for language model assistance in understanding linguistic nuances.


  • Write specific prompts to extract relevant information or summaries on specific research topics.
  • Create queries to generate insights, perspectives, or explanations on complex subjects.

For sure, the list above is not limited, and RPE can be applied also in such cases, as:

  • Prompts development to obtain step-by-step solutions for mathematical problems or scientific inquiries.
  • Drafting of prompts to stimulate creative thinking and idea generation for various projects.
  • Prompts designed for extracting concise and informative summaries of articles, documents, or texts.
  • Developing the prompts to simulate conversations with the language model for training AI chatbots.
  • Create queries to practice or fine-tune AI conversational interactions with the model.

The Paradox of Reverse Prompt Engineering

The paradox of RPE stands as a loop of actions we do: we want to generate a prompt but we actually generate it while trying to achieve the result. We find ourselves in a cycle of non-stoppable designing of prompts to generate more prompts. This sounds like an endless prompt engineering

As far as we know, Reverse Prompt Engineering is where we generate a prompt using an LLM model, but the point is that the input itself is a prompt. So, how can we be sure that this entire technique is even reliable? How do we know that the prompts we are using to generate the “production-ready prompts” were accurate in the first place? That is an interesting question.

As far as the prompts employed in Reverse Prompt Engineering are considerably simpler than the eventual "production-ready prompts" we aim to create using this technique. 

Despite the paradox, we can rely on Reverse Prompt Engineering to assist us in developing those "production-ready prompts" with a sense of assurance. It's crucial to recognize that formulating effective production-level prompts is an iterative undertaking, involving refinement and adjustments. Asserting that prompts generated through Reverse Prompt Engineering are immediately flawless would be both unjust and inaccurate.


Reverse Prompt Engineering or Reverse Prompt Development is a new step to Generative AI. It may be used as a powerful tool for different business categories: starting from super small startups, and finishing with large enterprises. 

There are many industries where RPE can be applied:

With the help of reverse engineering coding, a lot of prompt engineers may achieve really great results in proper prompt drafting. Springs, as a top-notch AI/ML development company, recommends using Reverse Prompt Development while testing prompt creation with various language models to achieve the best results.
