What is Prompt engineering?

Prompt engineering is preparing step-by-step instructions for different topics you are crafting so that you can achieve better results from the large language models (LLMs). 

LLM is an artificial intelligence system that has been trained to respond to queries after compiling a variety of data sets. After that, it will react to you in accordance with the cues you gave it and assist you in completing tasks like generating text, translating languages, and writing different kinds of creative content. However, LLMs can only generate outputs that are consistent with the prompts they are given

Today, we are the generation that sees the evolution and emergence of AI. Artificial intelligence is not a new buzzword for anyone these days. Almost everyone uses chatbots, Chatgpt, and Google Bard to get answers to their questions or to translate their feelings into words. Even though Chatgpt and Bard, our deep learning models and chatbots, are incredibly skilled at answering your questions, there are instances when we have noticed that these LLMs are unable to provide an accurate response to any of our queries. 

These LLMs are not accurately answering your query because they are not receiving the exact commands.

Why is prompt engineering trending?

Professionals with the ability to design effective prompts to guide large language models (LLMs) are in greater demand as these models become more and more popular in a range of applications.

LLMs have demonstrated their extraordinary abilities and adaptability beyond writing and generating text to translating languages, as demonstrated by Chatgpt, Bard, and others. By providing prompts, you open up these LLMs to a wider audience and allow people who do not know much about AI to use them for a variety of purposes. 

The need for AI-powered solutions is expanding like the universe across all domains. Many small and large businesses are using artificial intelligence to enhance decision-making, customer service, and process automation. 

Reports by Gartner indicate that up to 80% of organizations will incorporate AI by 2025. This surge in AI adoption fuels the need for prompt engineers who can develop and deploy AI-powered solutions, ensuring organizational goals.

Even though this is a relatively new industry, people are embracing it quickly. But you must ensure some facts before using it. See the following for advice on using prompt engineering.

Why does today’s world require prompt engineering?

These days, we have resources at our disposal, but knowing how to use them optimally can vary with a few simple guidelines. 

Here’s a simple example to help you grasp this idea, if you search for any unethical item on Google, it will not display the results you need. However, if you tell it that you need the information for educational purposes, it will display the results you need based on your educational background.

Consider the following example. If you search for the circumference of a circle on LLM, you will find that C = 2 \pi r. But when you give it the required prompts, it can tell you each and every aspect of the circumference with real-life examples. 

The next example you can think of involves several organizations. Teachers can create individualized learning materials and assessments by creating powerful prompts, which will improve student engagement and knowledge acquisition in an increasingly digital learning environment.

Furthermore, in the current context, prompt engineering is required for several reasons. Check out below

• To harness the power of large language models (LLMs): LLMs are a new type of AI model that can generate text, translate languages, write different kinds of creative content, and answer your questions in an informative way. However, LLMs are still under development, and they can produce inaccurate or irrelevant outputs if they are not carefully guided. Prompt engineering is the process of designing and optimizing prompts to guide LLMs to generate desired outputs.
• To democratize access to AI:  Prompt engineering makes it easier for people without a background in computer science or machine learning to use LLMs. This is important because LLMs have the potential to revolutionize many different industries and applications.
• To develop new and innovative AI applications: LLMs are still a relatively new technology, and their full potential has not yet been realized. Prompt engineering is a key tool for exploring the capabilities of LLMs and discovering new ways to use them.

Types of Prompt Engineering

There are many different types of prompt engineering techniques, but some of the most common include:

1. N-shot prompting: This technique involves providing the LLM with a few examples (N-shots) of the desired output before asking it to generate its own output. This can be used for a variety of tasks, such as translation, summarization, and code generation.
2. Chain-of-thought (CoT) prompting: This technique involves breaking down a complex task into a series of smaller, simpler tasks. The LLM is then instructed to complete each task sequentially, with each task’s output serving as the input for the subsequent task. This can be used for tasks such as question-answering and problem-solving.
3. Generated knowledge prompting: This technique involves generating prompts that contain additional knowledge or information that the LLM may not have been trained on. This can be used to improve the accuracy and completeness of the LLM’s output.
4. Positive and negative prompting: This technique involves using both positive prompts (prompts that encourage the LLM to generate certain types of output) and negative prompts (prompts that discourage the LLM from generating certain types of output). This can be used to control the style and tone of the LLM’s output, as well as to prevent it from generating harmful or offensive content.
5. Interactive context-aware prompting: This technique involves iteratively refining the prompt based on the LLM’s output. This can be used to help the LLM understand and respond to complex or ambiguous prompts.
6. Role-playing prompting: This technique involves instructing the LLM to take on a specific role or identity when generating its output. This can be used to generate more creative and engaging outputs, such as poems, stories, and scripts.
7. Multiple Choice Question (MCQ) Prompting: This method consists of giving the LLM several options for a single question, with the instruction to choose the correct answer from the list.

• Security: Prompt engineering could be used to exploit LLMs for malicious purposes, such as generating fake news or disinformation. It is important to develop safeguards and security measures to mitigate these risks.

Main ideas to keep in mind while designing prompts for AI models

1. Be specific: First and foremost, users should remember that when interacting with the AI model, they must be extremely specific. The more specific you are in your prompt, the better the model will be able to understand what you want it to do. For example, instead of saying Write a story, you could say Write a science fiction story about a group of astronauts who discover a new planet.

2. Be succinct and clear: Do not use ambiguous, baffled, or perplexing wording in your prompt. It is important to keep in mind that the commands you are giving are directed towards a machine, not a person. It does not have its own memory to understand. It is important to emphasize that the model must comprehend precisely what you are asking of it.

3. Provide context: The model will be better able to produce pertinent and educational outputs the more context you can give it. For example, if you are asking the model to translate a sentence, you should provide it with the original language and the target language.

4. Consider the format of the output: Do you want the model to generate text, code, an image, or something else? Be sure to specify the desired format in your prompt.

5. Give examples (If Possible): You can help the model learn what you are looking for by giving examples of the desired output. For example, if you are asking the model to generate a product review, you could provide it with examples of positive and negative reviews.

6. Get feedback before asking for Final Output: Once the model has generated an output, review it and provide feedback. This will support the model’s ability to grow over time and learn from its errors.
