    The term “AI” has been mentioned frequently over the past few years, thanks to significant breakthroughs in the technology behind it. Artificial Intelligence, or AI in short, is a broad technological term used to describe the concept of enabling computers to simulate human learning processes. 

    People often use the term “AI” to describe anything that involves computer intelligence, even though there are many distinct subfields under the AI umbrella itself. Therefore, in this article, we will break down the concept behind AI and its various categories so that we can use the correct terminology when describing applications that involve computer intelligence.

    What is Artificial Intelligence (AI)? 

    Artificial Intelligence (AI) refers to a concept that enables computers to simulate human learning processes. By combining mathematical concepts such as statistics, calculus, linear algebra, and AI-ready data we can build learning algorithms that allow computers to mimic how humans learn: classifying objects, recognizing patterns, and responding to messages in natural human language in a coherent manner, etc. 

    Large Language Models (LLMs) such as ChatGPT, Claude, and Gemini are among the major success stories of AI. Millions of people have integrated these tools into their daily work to boost productivity. However, there is a growing misconception that AI refers only to these LLMs, when in fact many other forms of AI exist. LLMs are currently the most sophisticated AI systems available, and they themselves are built upon several different AI subfields, which will be discussed next.

    Key AI-Related Terms and Concepts 

    In this section, we’re going to dissect different subfields of AI in terms of their definitions and concepts. At the very least, we can divide AI into four different subsets: machine learning, deep learning, generative AI, and agentic AI. 

    Machine Learning (ML) 

    Machine learning (ML) is a subset of AI that focuses on enabling computers to learn patterns from data. Unlike traditional software, which follows fixed, explicitly programmed rules, ML systems do not produce strictly deterministic outputs; their behavior can change depending on the data they are trained on. Additionally, ML systems can improve their performance over time as they are exposed to more data. 

    There are two common machine learning approaches based on how the learning process is conducted: 

    • Supervised learning: Ground-truth labels are provided with the training data, allowing the model to learn the relationship between inputs and known outputs.
    • Unsupervised learning: No ground-truth labels are provided during training. The system attempts to discover underlying patterns or structures in the data on its own. 

    Deep Learning (DL) 

    Deep learning (DL) is a specialized subfield of ML that uses artificial neural networks with multiple layers to capture complex patterns in our data. As the name suggests, these networks are inspired by the structure of the human brain and are particularly effective for tasks involving large amounts of unstructured data, such as image recognition, speech recognition, and natural language processing. Most modern AI breakthroughs like LLMs rely heavily on deep learning techniques. 

    Generative AI 

    Generative AI refers to AI systems designed to generate new content rather than simply analyze or classify existing data like ML or DL. The content can be anything from text, images, audio, video, or even code. As you can guess, popular LLMs that we know as of now can be categorized into generative AI, as they can generate coherent and context-aware responses. 

    Agentic AI 

    Agentic AI takes the concept of Generative AI into one step ahead. It refers to AI systems that can autonomously make decisions, plan actions, and interact with their environment to achieve specific goals. Unlike Generative AI that respond only when we give them direct inputs, agentic AI systems can take initiative and perform multi-step tasks. 

    As an example, let’s say you want to research a topic, summarize key findings, and prepare a presentation. An agentic AI system could independently search for relevant information, evaluate sources, organize the content, and generate a structured output for you without your intervention. 

    Types of AI 

    So far, we have discussed different subfields of AI in terms of their concepts. Now, let’s talk about different types of AI in terms of their capabilities of performing tasks. 

    Weak AI (Narrow AI) 

    Weak AI or sometimes also referred to as Narrow AI are AI systems designed to perform a specific task or a limited set of tasks. These systems operate within predefined boundaries and cannot generalize their intelligence beyond their intended purpose. 

    As an example, a deep learning model specifically trained to recognize animal images would not perform well when we use it to recognize random objects. Despite their limitations, weak AI systems can outperform humans in their specialized domains. Weak AI are commonly used in applications like voice assistants, recommendation engines, facial recognition, or medical diagnosis tools, where focused performance and efficiency are more important than broad, human-like understanding. 

    Strong AI (General AI) 

    Strong AI is the opposite of Weak AI. It refers to AI systems capable of performing a wide range of tasks. AI systems under this category are capable of understanding, learning, and solve a wide range of tasks without task-specific programming. 

    In theory, strong AI would possess a human-like general intelligence, which enables it to reason, adapt to new situations, and transfer knowledge across different domains. However, no true strong AI systems exist as of now, since the current technologies still operate within certain limitations and lack of consciousness. Although LLMs can handle a wide variety of tasks and can perform in an agentic manner, they are still considered advanced forms of narrow AI rather than true strong AI.

    Benefits and Challenges 

    As AI continues to evolve, its impact on companies becomes increasingly significant. While AI offers transformative advantages that reshape how companies operate, it also introduces new risks and challenges that must be carefully assessed. Understanding both sides is important for companies such that they can adopt AI responsibly and strategically. 

    Benefits of AI in Business 

    There is no doubt that the advancement of AI brings significant benefits for both individuals and companies. The most notable benefit is the increase in productivity, efficiency, and value creation across several business domains. For example, programmers can now use AI as an assistant to ship production-ready code and resolve bugs in a matter of minutes or days instead of months. Accountants can also leverage AI to double-check bookkeeping records. Similarly, marketing departments can use AI to brainstorm content ideas and generate initial drafts for product promotion scripts and campaigns. 

    In terms of security, AI systems are capable of detecting anomalies within seconds, identifying potential threats before they occur, and responding to incidents faster than human intervention. Credit card transactions can now be monitored using AI to detect and prevent fraudulent activities in real time. 

    From a governance and operational perspective, AI enables better decision-making through data-driven insights. AI also optimizes workflows in manufacturing industries by improving resource allocation, predicting system failures, and therefore, reducing operational costs. 

    Challenges of AI in Business 

    Despite all of the benefits mentioned above, integrating AI into business operations is still not straightforward. Companies must carefully address multiple challenges, such as data breaches, model exploitation, and adversarial attacks. Also, misuse of AI remains a concern until now, as these technologies can be deliberately exploited to generate harmful or misleading content. 

    Governance is another major concern, as companies must address issues related to data privacy, regulatory compliance, transparency, and accountability of AI-driven decisions. Companies need to maintain transparency and accountability in AI-driven decision-making, particularly in regions with strict data protection regulations. 

    Meanwhile, from an infrastructure perspective, AI adoption often requires significant investment in computing resources, data pipelines, and system integration. Moreover, poorly designed AI systems can also introduce bias, which could reduce trust and diminishing the expected business value if not managed carefully. 

    AI Applications and Use Cases

    The following examples highlight how AI is being applied across different companies and the value it delivers in practical applications.
