From voice assistants to business automation platforms, artificial intelligence (AI) has become an integral part of our lives. However, one key aspect of making the most of an AI model’s potential is often overlooked: prompting.
Formulating clear, well-structured prompts—a practice known as prompt engineering—is essential for obtaining accurate and relevant responses from advanced models such as ChatGPT.

What is a prompt?
A prompt is a request or command provided to an artificial intelligence model as input so that it can generate a response.
For example, when we ask a generative AI model , “Explain Einstein’s theory of relativity in simple terms, as if you were talking to a 10-year-old,” we are providing a “prompt” that the AI uses to generate its response.
In an AI model, there are three key components:
- System: Defines general settings, such as the tone and style of responses; for example, we can specify that the system respond in a formal or informal manner, or that it adopt a specific persona, such as a lawyer or a doctor.
- User: The user who interacts directly with the system by entering questions and receiving answers.
- Assistant: This is the artificial intelligence itself, which processes prompts and generates results based on the input it receives.
Each actor plays an important role in the prompting process, directly influencing the quality and relevance of the responses generated by the model.
How does prompting work in AI?
When we formulate a prompt, the AI processes the request based on its prior knowledge, striving to provide an accurate response. However, the model has no knowledge beyond its training data, which constitutes the scope of the data on which it was trained: this means that the quality of the prompt has a decisive impact on the output.
An important aspect of prompting is its ability to influence an AI’s behavior. For example, we can ask the model to take on the role of a teacher or an expert in a particular subject, thereby opening the door to a variety of creative possibilities.
Extending AI Capabilities with Function Calls
Now let’s imagine we want to solve a complex equation: in this case, the model might require a function call—that is, a predefined external function—to perform advanced calculations. For example, if we ask the model to solve a system of differential equations, it can call an external function (such as an API or a software library) specialized in numerical computation to obtain the result.
The use of function calls is particularly useful for overcoming the inherent limitations of AI, such as its inability to perform complex calculations or retrieve data in real time.
Let’s look at three concrete examples:
- Financial Sector: A system could use a function call to access real-time financial data and make investment decisions.
- Virtual assistants: A conversational bot could use a function call to make a reservation at a restaurant or hotel.
- Document Generation: An LLM model could make a function call to automatically generate a PowerPoint presentation or a Word document.
Types of Prompting: Zero-Shot, Few-Shot, and RAG
There are various prompting techniques that can be used to elicit responses from an AI model. Each method has its own strengths and weaknesses, making it suitable for different situations.
Zero-Shot Prompting
In Zero-Shot Prompting, we provide the AI with only the prompt, without any additional information or examples. The AI attempts to generate a response based solely on the prompt it receives.
This method is quick, but it can be inaccurate for complex tasks.
Few-Shot Prompting
Using a technique called Few-Shot Prompting, we provide the AI with one or more examples before asking the question. For example, if we want ChatGPT to answer a scientific question, we can provide examples of similar answers to help it better understand the context.
This method significantly improves the quality of the responses.
Retrieval-Augmented Generation (RAG)
Another interesting technique is called Retrieval-Augmented Generation (RAG). With RAG, the AI enriches its responses using a customized database of information.
This method is particularly useful in so-called “closed” chatbots, where the system must operate within predefined boundaries, ensuring consistent and relevant responses only in relation to specific information.
Strategies for More Effective Prompting
To get the most out of AI prompting, it’s not enough to simply ask a question; it’s essential to use specific strategies. Here are some practical tips:
- Clear wording: Using direct and precise language is essential to avoid ambiguity or vague answers. An example might be “Explain to me how photosynthesis works, ” rather than a vague question like “What is photosynthesis?”
- Natural language: Formulating prompts as if you were speaking to a person helps the AI better interpret your requests. For example, “Can you tell me how the feudal system works?” is preferable to an overly technical question like “Describe the socioeconomic structure of feudalism.”
The Most Advanced Techniques: Chain of Thought
The Chain of Thought technique guides the AI through a series of logical steps to produce a more detailed and comprehensive response.
For example, if we ask the AI to solve a math problem such as “Calculate how many days there are in 3 months, ” we could structure the prompt so that the AI performs a series of logical steps: first, determine how many days there are in a month; second, multiply that number by 3, specifying that the answer must distinguish between months with 30 and 31 days. This step-by-step structure allows the AI to provide a more precise answer than a single, generic command such as “How many days are there in 3 months?”
By applying these prompt engineering strategies, we can improve the effectiveness of our interactions with AI, yielding more detailed and relevant responses.
Examples of prompts for ChatGPT and other LLM models
One way to better understand the power of prompting is to look at concrete examples:
An effective prompt for ChatGPT might be:
“Pretend you’re a doctor specializing in nutrition and explain to a patient how to balance the macronutrients in their daily diet to maintain a good energy level.”
In this case, we are asking the AI to take on the role of an expert and provide practical, detailed advice on a specific topic in a clear and accessible way, suitable for a non-expert audience.
In the context of code autocompletion, an effective prompt might be:
“Complete this Python code snippet that calculates the sum of the numbers in a list: def calculate_sum(list):”
In this case, the prompt provides a clear and specific request that allows the AI to perform the task appropriately, focusing on a well-defined operation.
These structures help the AI provide relevant and targeted responses, offering a solution based on what is requested in the prompt. The use of well-formulated prompts improves the output generated by LLM models. In technical jargon, the term “contextual alignment ” refers to how prompt engineering techniques allow us to create questions that “align” the AI’s response with the desired context, thereby improving its effectiveness.
The Role of the Prompt Engineer
The Prompt Engineer is an emerging professional role focused on designing and optimizing prompts to elicit high-quality AI responses. This professional must have a deep understanding of how artificial intelligence models work and know how to adapt prompts to meet the specific needs of a company or user.
For example, a Prompt Engineer might design custom prompts for a chatbot used in customer service, ensuring that the responses are accurate and relevant to users’ frequently asked questions (FAQs). As the use of LLM models increases, this role will become increasingly essential in the fields of research,automation, and customer care.

Prompt engineering is a key factor in improving the effectiveness of our interactions with artificial intelligence. Prompting techniques offer powerful tools for managing advanced models such as ChatGPT. However, it is important to consider the limitations of large language models (LLMs) and implement advanced strategies—such as the use of function calls or the RAG technique—to further improve responses.
