What is an AI agent?

An AI agent is a computer program capable of performing tasks autonomously by simulating analytical and decision-making abilities comparable to those of humans, such as perception, reasoning, and decision-making. Using advanced artificial intelligence algorithms, it can interact with its environment, learn from its experiences, and adapt to optimize its performance. Used in various fields such as customer service, finance, healthcare, and logistics (among others), AI agents facilitate the automation of complex processes and improve operational efficiency. Thanks to advances in machine learning, natural language processing (NLP), and natural language understanding (NLU), these agents are becoming increasingly capable and versatile, making their adoption essential for businesses.

Artificial intelligence agents have three main characteristics:

Autonomy: they can operate without human intervention, make decisions, and perform tasks independently. Although they receive initial instructions, they determine for themselves the best way to accomplish a mission, which makes them particularly effective at managing complex processes in real time.

Continuous learning: thanks to feedback whether from advisors or their environment, these agents continuously improve. They adapt their behavior based on the results they obtain, allowing them to evolve and make increasingly accurate decisions over time.

Reactivity and proactivity: they are capable of responding to environmental changes in real time (responsiveness) while anticipating trends and recurring events to optimize their performance (proactivity). For example, an AI agent in customer service can analyze and categorize the reasons users contact the service, instantly answer frequently asked questions, and escalate complex requests to a human agent, all while anticipating customer needs by analyzing past interactions.

The difference between an AI agent and agentic AI

The concept of agentic AI emerged at the same time as the concept of an AI agent. However, the two differ fundamentally in their degree of autonomy and their ability to take initiative. An AI agent often operates within a more regulated and controlled framework, where its actions are directly influenced by the person using it. In contrast, an agentic AI possesses a higher degree of autonomy and can make more decisions on its own. It is designed to learn, adapt, and optimize its actions without constant human intervention. In other words, an AI agent is an intelligent executor, while agent-based AI is more akin to a strategic system capable of planning and anticipating its own actions.

The difference between an AI agent and an AI chatbot

The terms "AI agent" and "AI chatbot" are often confused, even though they refer to distinct concepts in the field of artificial intelligence. An AI chatbot is a program designed primarily to interact with users via text or voice interfaces, answering questions or performing simple tasks based on predefined scenarios (these are also referred to as pre-configured or scripted chatbots).

In contrast, an AI agent is a more advanced and specialized entity that can understand, reason, and act autonomously based on its environment. It uses data and information to achieve specific objectives, such as responding to customer requests in the context of after-sales support. These agents use advanced technologies, such as machine learning and natural language processing, to continuously improve and adapt to user preferences. A chatbot, on the other hand, is generally used to answer questions and provide basic information. Its role is limited to exchanging information; it lacks the ability to perform actions or make complex decisions.

Beyond chatbots. An AI agent that really works!

This confusion between AI agents and AI chatbots stems largely from the rapid evolution of technology and the interchangeable use of these terms in marketing and communications. Indeed, with the emergence of increasingly powerful artificial intelligence solutions, the line between chatbots and AI agents is becoming increasingly blurred. Advances in natural language processing and deep learning have thus enabled chatbots to offer richer and more engaging interactions similar to those of AI agents further fueling this confusion.

How does an AI agent work?

To function effectively, an AI agent relies on several essential elements:
Perception: when a customer makes a request, the AI agent captures and analyzes the information to respond effectively. This perception relies on physical sensors (microphones, cameras) and virtual sensors (APIs, knowledge bases). Physical sensors enable speech recognition and image analysis, while virtual sensors access databases and online resources to enhance understanding of the requests. In customer relations, this perception is essential for identifying the customer’s intent, analyzing data, and providing a tailored response, ensuring a smooth and effective interaction. This is the strength of NLU (Natural Language Understanding), which enables the accurate understanding and interpretation of requests for an optimal response.

Processing and reasoning: it analyzes this data using machine learning algorithms, symbolic logic, or other approaches such as Retrieval-Augmented Generation (RAG). This processing may include extracting information from a knowledge base, pattern recognition, and decision-making based on probabilities or predefined rules.

Action: based on its analysis, the agent performs an action, such as answering a question or adjusting system settings. For example, it can modify a customer’s subscription based on their needs or update communication preferences for personalized support. These actions can be simple, such as generating text, or more complex, such as automatically creating a ticket in the ERP system when a customer reports an issue, and assigning the request to the appropriate department for prompt resolution.

Learning and Adaptation: using deep learning or reinforcement learning techniques, the agent improves its performance over time. It can adjust its responses based on user feedback, refine its predictive models, or even learn new tasks from previously unseen data.

The different types of AI agents

There are several types of agents, distinguished by their degree of autonomy and sophistication:
Reactive agents: these respond in real time to customer requests without maintaining a history. They are ideal for services requiring immediate assistance, such as customer support chatbots handling frequently asked questions or automated response systems. Their speed of execution ensures seamless, 24/7 service, reducing wait times and improving customer satisfaction.

Model-based agents: these agents use an internal model to anticipate the consequences of their actions. Examples: advanced chatbots. Unlike reactive agents, these agents store and use historical data to refine their decisions and optimize their responses, making them ideal for voice assistants or customer service platforms.

Goal-based agents: they plan their actions based on a defined goal, optimizing their decisions. These agents are capable of making strategic decisions by evaluating multiple scenarios and adjusting their behavior based on the results obtained. They are commonly found in customer service, where they operate based on tests and measurable objectives. They evaluate past interactions, perform predictive analytics, and dynamically adjust their strategies based on the results obtained.

Self-learning agents: they adjust their behavior based on feedback, such as Google DeepMind’s AI. Thanks to machine learning and deep neural networks, these agents continuously improve their performance and can outperform expert advisors in their field on complex tasks, such as AI-assisted medical analysis, autonomous drone piloting, and advanced industrial robotics.

The risks and limitations of AI agents

One of the key aspects of the proper use of AI agents involves the collection and processing of personal data. These systems enable the efficient management of information such as names, addresses, banking details, and medical records. However, to ensure their security, it is essential to apply best practices for data management and protection. Regulations such as the GDPR and the AI Act provide a framework to ensure optimal transparency and compliance. By integrating advanced security protocols and training teams, it is possible to fully harness the potential of AI while ensuring responsible and secure use of data.

Automating customer interactions with AI should not be viewed as a cause for concern, but rather as a valuable tool in day-to-day operations. By taking on repetitive, low-value-added tasks, these technologies allow customer service representatives to focus fully on the essence of their job: building customer relationships and solving complex problems. For successful integration, it is essential to view these tools as strategic allies and to train teams to collaborate effectively with the AI agent.

Artificial intelligence models (LLMs), while powerful, can generate incorrect or inconsistent responses, a phenomenon known as “hallucination.” Furthermore, these models often operate as “black boxes,” making it difficult to understand the decisions they make. This lack of transparency can pose challenges in terms of accountability and regulatory compliance. To minimize these risks, it is essential to implement human validation mechanisms and integrate trustworthy AI. The LLM-as-a-Judge agent supervises and then validates the responses from AI systems, ensuring more reliable decision-making. This quality control improves the traceability of decisions and enables the use of explainable models to ensure a safer and more ethical use of AI agents.
