AI agents have become one of the most popular topics of conversation today, particularly among early adopters and AI enthusiasts. Many businesses across various industries are trying to understand how to implement AI agents in their operations, while many are already testing or using them. Following AI and ML trends, we became curious about the capabilities of agentic AI to transform decision-making, automate workflows, and enhance user experiences. And why Forbes calls 2025 the year of Agent AI. So let’s find out what’s in it.
What are AI Agents?
AI agents are software programs that operate either autonomously or semi-autonomously. They effectively understand the environment where they operate, analyze data, make informed decisions, and take decisive actions to achieve specific goals
Before making any business decision, it’s crucial to assess the value of the technology being considered. This means understanding its core functionality, capabilities, and potential impact.
Today, we’re focusing on AI agents – exploring how they work and the potential benefits they bring to businesses. We’ve already started uncovering their essence, so let’s dive deeper into the subject.

How do AI Agents work?
AI agents function through a combination of software, algorithms, and hardware components. The technologies that empower their effective operation involve:
Machine Learning & Deep Learning
ML/DL models help process data, recognize patterns, and improve decision-making. Common frameworks include TensorFlow, PyTorch, and Scikit-learn.
Natural Language Processing
AI agents utilize NLP models such as GPT and BERT for effective communication and understanding of human language.
Sensors
Some AI agents interact with the physical world using sensors, including:
- cameras (used in autonomous vehicles and robotics for object detection and navigation)
- temperature and motion sensors (common in smart home assistants and industrial automation)
- microphones and speech recognition (enable voice assistants like Siri and Google Assistant to understand and respond to commands)
Computer Vision
AI agents utilize image recognition and video analysis to understand their environment. Key technologies: OpenCV, YOLO, and CNNs.
Cloud Computing
Cloud platforms such as AWS, Google Cloud, and Microsoft Azure offer the necessary computational power to run AI models.
However, the choice of technology depends on the type of AI agent required for the specific case, so the next step is to determine which type of AI agent best fits the intended application.
What are the Types of AI Agents? What Can AI Agents Do?
The information about the types of AI agents and their quantity varies by source, but we will cover all the known ones at this time:
1. Simple reflex agents
It operates solely based on predefined rules and the immediate data it receives. These agents are suitable for simple tasks that do not require extensive training: sorting incoming emails into predefined categories based on detected keywords.
2. Model-based reflex agents
A model-based agent evaluates possible outcomes and their implications before making a choice, instead of simply following rigid rules. In a smart thermostat, such a system might analyze factors like current temperature, weather forecasts, and user preferences to predict the optimal temperature settings for the home, rather than just responding to a simple command.
3. Goal-based agents
These agents compare various strategies to determine the best way to achieve their desired outcomes. They are particularly well-suited for performing complex tasks, including natural language processing (NLP) and robotics applications. For instance, in a customer support chatbot, such an AI agent might compare various response strategies to provide the most accurate and helpful answer to a user’s query, considering past interactions, user sentiment, and contextual data to craft the best response.
4. Utility-based agents
The utility-based agent is primarily concerned with optimizing outcomes based on a predefined set of preferences or values, ensuring the highest benefit for the user. It can help users find the most convenient delivery options, prioritizing faster delivery times over cost, and ensuring they receive their package as quickly as possible, regardless of the price.
5. Learning agents
A learning agent distinguishes itself by continuously improving its performance over time. Unlike the other agents, which follow predefined rules, models, or utility functions, a learning agent actively learns from past experiences and adapts its strategies to achieve better outcomes in the future.
As an example, for an online streaming platform (Netflix or YouTube), a learning agent continuously learns from user behavior. It tracks which movies or shows a user watches, how much time they spend on them, and their ratings. Over time, the agent adapts its recommendations based on this accumulated data, improving its suggestions to align more closely with the user’s preferences.
6. Hierarchical agents
Hierarchical agents differ from the previously discussed ones in their structured decision-making process. They organize their actions in a multi-level system, where decisions are made at various layers of abstraction. Each layer is responsible for different tasks, which allows for more complex problem-solving and efficient handling of larger tasks.
For example, in a robotic vacuum cleaner, a hierarchical agent might first decide on the high-level goal (cleaning the entire house), and then delegate the task to lower-level agents responsible for specific rooms, paths, or obstacles. The higher-level agent might reassess the progress or goals, while the lower-level agents focus on navigating and cleaning. This layered structure allows the agent to effectively handle complex tasks without becoming overwhelmed by individual details.
7. Collaborative agents
Collaborative agents are capable of coordinating, communicating, and sharing information to improve overall performance, solve problems, or complete tasks that would be difficult for a single agent to handle alone. In a smart home system, collaborative agents work together to optimize comfort and energy efficiency. One agent monitors temperature, while another controls lighting based on occupancy. If a room is unoccupied, the temperature agent notifies the lighting agent to dim the lights, saving energy and ensuring seamless operation.
AI Agents vs. Advanced Automation – What’s the Difference?
Not all AI systems qualify as true AI agents. While automation tools can enhance workflows and support decision-making, genuine AI agents must function “a little” differently. How can you distinguish between them?
- Autonomy – an AI agent acts independently rather than relying on pre-programmed rules.
- Learning ability – AI agents adapt based on feedback, while automation tools follow fixed processes.
- Goal-oriented behavior – AI agents dynamically adjust their strategies to achieve goals instead of executing rigid scripts.
- Resilience – AI agents continue functioning even when unexpected variables arise, whereas automation tools often require human intervention when things don’t go as planned.
- Does the system require constant human input to function?
- A) No, it operates independently and takes action on its own.
- B) Yes, it follows predefined rules and needs human approval.
- Can the system adapt based on feedback and improve over time?
- A) Yes, it learns from past actions and evolves.
- B) No, it sticks to its initial programming.
- Does it have dynamic goal setting, adjusting its approach as needed?
- A) Yes, it shifts strategies based on real-time data.
- B) No, it executes fixed workflows without adjusting.
- What happens if the environment changes unexpectedly?
- A) The system recognizes the issue and adjusts its behavior.
- B) It gets stuck or fails without intervention.
- Does it make decisions based on reasoning and data analysis?
- A) Yes, it analyzes data and determines the best course of action.
- B) No, it simply executes predefined steps.
