What is agentic AI? Definition, examples, and how it works

Agentic AI is an advanced form of artificial intelligence that can independently set goals, plan, reason, and take action to achieve a specific objective with minimal human oversight.

Unlike traditional AI, which is reactive and responds to direct commands, agentic AI is proactive and can initiate tasks on its own. It is characterized by its autonomy, goal-orientation, reasoning, adaptability, and collaborative capabilities.

To help you grasp the cutting-edge of AI, we’ll break down agentic AI, explaining how it plans, reasons, and acts to achieve goals. Discover practical examples of its use in business, finance, and healthcare, and learn exactly how it differs from generative AI so you can understand which is the right tool for the job.

What is agentic AI?

Agentic AI is a type of artificial intelligence that reacts to commands and actively takes initiative to accomplish specific goals.

While traditional AI systems are designed to carry out predefined tasks in response to clear input (like answering questions or sorting data), agentic AI operates with a high degree of autonomy. It can function independently, perceive its environment, analyze data, “reason” about the next action, and act to achieve a goal without needing constant human intervention.

To put it into perspective, imagine a self-driving car. Traditional AI would simply follow pre-programmed commands, such as “navigate from point A to point B.”

Agentic AI goes a step further. It’s capable of analyzing changes in the environment (for example, road conditions or traffic patterns), reasoning potential obstacles, and adapting its behavior (like rerouting or slowing down) to reach the destination safely.

This shift from a reactive model (where AI only reacts to input) to a proactive one (where AI takes independent action to achieve an outcome) is one of the defining features of agentic AI.

Whether optimizing business processes or managing a smart home, agentic AI doesn’t just follow instructions – it anticipates needs, solves complex problems, and learns from experience to improve its performance over time.

How does agentic AI work?

To understand how agentic AI works, think of it as a cycle of perception, reasoning, action, and learning. This feedback loop allows the AI to function autonomously, make decisions, and take actions that bring it closer to its goal. Let’s explore each stage in detail:

1. Perception

This is the first stage, where the AI “perceives” its environment by collecting data from its surroundings. It could use hardware or fetch data from external systems by setting up the model context protocol (MCP) and application programming interface (API).

In a smart factory, for example, the AI might collect real-time data on machinery conditions. Meanwhile, agentic AI in a self-driving car gathers data through cameras, LiDAR, and radar to understand the road and its surroundings.

2. Reasoning

Once the data is collected, the AI processes it to understand the situation. It breaks down complex problems into smaller, manageable tasks.

For example, an AI tasked with optimizing a supply chain might receive data about current stock levels, supplier delays, and customer demand. The AI then analyzes this information and determines the best course of action, such as adjusting production schedules or finding alternative suppliers.

An agentic AI on a self-driving car, on the other hand, may use data about the current traffic situation, road conditions, and weather.

3. Action

After reasoning through the data, the AI takes actions to achieve the goal. In the supply chain example, this could involve rerouting a shipment, making a recommendation to users, or activating a system (such as turning on a machine or adjusting a thermostat).

Meanwhile, in an autonomous vehicle, this stage involves adjusting the car’s speed, changing direction, and stopping when necessary.

4. Learning

The final stage of the agentic AI cycle involves learning from the previous actions’ outcomes. It assumes questions like:

• Did the action help the AI achieve its goal?
• If not, what can be improved?
• Would I reach the goal if I did A instead of B?

The AI adjusts its behavior based on this feedback, becoming more effective and efficient over time. For instance, a warehouse AI that detects a bottleneck in the supply chain will learn from the delay and improve its future actions by adjusting routing or scheduling.

This continuous feedback and refinement cycle allows agentic AI to operate with increasing efficiency and autonomy. With each iteration, it becomes better at understanding complex situations and optimizing its actions to achieve its goals.

Key characteristics of agentic AI

Here are the core characteristics that define agentic AI, allowing it to function efficiently and independently:

Autonomy

As the cornerstone of agentic AI, autonomy refers to the system’s ability to operate almost entirely independently. This allows it to complete tasks without constant human intervention.

For instance, in a smart home, an autonomous assistant could monitor energy consumption, detect anomalies, and adjust the thermostat settings accordingly to ensure optimal comfort and efficiency. The system takes the initiative and doesn’t need humans to manually adjust the settings.

Goal-oriented

Agentic AI is specifically designed to achieve goals, rather than simply responding to commands. Once it understands its objectives, it breaks them down into actionable tasks and carries them out autonomously.

For example, an AI in customer support may aim to resolve issues efficiently. It would first assess the customer’s query, select the best response or action (e.g., providing troubleshooting steps, routing to a human agent), and then execute it automatically.

Reasoning and planning

Agentic AI doesn’t just act blindly; it reasons through complex problems and plans its actions. By analyzing multiple scenarios and considering possible outcomes, it formulates a strategy to achieve its goals.

For instance, an AI agent tasked with optimizing a supply chain would not simply follow a preset routine. It would analyze dynamic inventory data, assess current demand, and predict future needs, allowing it to plan for delays, reallocate resources, or streamline operations to minimize inefficiencies.

Adaptability

In real-world scenarios, things rarely go according to plan, and agentic AI must adapt to new information or changing conditions.

For example, an AI-powered robot in a warehouse might encounter unexpected delays or changes in inventory levels. It must adapt by finding an alternate route or adjusting its task priorities, ensuring that operations continue smoothly even in the face of uncertainty.

Proactive nature

One of the most powerful aspects of agentic AI is its ability to be proactive. Instead of waiting for instructions, agentic AI can anticipate problems and take action before they escalate.

Take the example of a predictive maintenance system in a manufacturing facility: the AI monitors machine performance and proactively schedules maintenance before a breakdown occurs, saving time and reducing costs.

Collaboration

Agentic AI can work in collaboration with other AI systems or human teams. This allows for more effective problem-solving and decision-making.

For example, an AI in the financial sector could work alongside human analysts to identify fraudulent transactions, improving accuracy and efficiency. It could autonomously flag suspicious activities while allowing the human team to focus on more complex cases.

Examples of agentic AI

Agentic AI is already transforming industries by taking on complex, multi-step tasks that were previously time-consuming or required human intervention. Let’s look at some real-world examples of how agentic AI is applied across various sectors:

Business process automation

The main role of AI in businesses revolves around automating administrative and operational tasks, allowing human employees to focus on higher-value work. For example:

• Invoice processing. AI agents can handle the entire invoicing process, like generating invoices, sending reminders for overdue payments, and even updating accounting records. This eliminates human error and accelerates payment cycles.
• Customer service. AI-driven chatbots can answer customer inquiries, resolve complaints, and offer personalized product recommendations. Hostinger is one of many companies already implementing AI systems to instantly answer inquiries or troubleshoot product-related issues for better customer satisfaction.

Manufacturing

The manufacturing sector is benefiting greatly from agentic AI, particularly in optimizing operations and reducing downtime. It can help with tasks such as:

• Predictive maintenance. AI agents can monitor equipment in real time, analyze sensor data, and predict when a machine might fail. Before the failure happens, the agent can schedule maintenance, order parts, and even reroute production to minimize downtime, keeping the factory running smoothly.
• Supply chain optimization: Agentic AI can predict fluctuations in demand and supply, enabling businesses to adjust their production schedules accordingly. It can also handle tasks like managing inventory levels, ordering materials, and coordinating shipments without human oversight.

Financial services

The financial sector is also seeing a huge impact from agentic AI, with applications in areas like risk management and trading. Examples include:

• Fraud detection. AI agents monitor transaction data in real time, using advanced algorithms to detect patterns indicative of fraudulent behavior. When suspicious activity is detected, the system can autonomously freeze accounts, notify customers, and even trigger further investigations.
• Automated trading. AI agents can autonomously execute trades based on market conditions, continuously analyzing vast amounts of financial data to optimize investment strategies. In high-frequency trading, agentic AI can make decisions in milliseconds, far faster than a human trader could react.

Healthcare

In healthcare, agentic AI is being used to support both diagnostic tasks and treatment plans, improving outcomes and efficiency. Examples include:

• Diagnosis assistance. AI systems can autonomously analyze medical records and imaging data (e.g., X-rays, MRIs) to detect diseases or abnormalities. For example, an AI system might scan a mammogram and identify early signs of breast cancer, alerting a doctor to review the case.
• Personalized treatment plans. Agentic AI can analyze a patient’s medical history, genetic data, and current health status to recommend personalized treatment options. It can autonomously suggest medications, lifestyle changes, or therapy plans and adapt the treatment as new information becomes available.

Agentic AI vs generative AI

Agentic AI and generative AI are two distinct types of artificial intelligence, each serving a different purpose. While they can sometimes work together, they are designed to handle different tasks.

The primary goal of generative AI is to create new content. This could include generating text, creating images, composing music, or even writing code. Generative AI systems analyze large datasets to learn patterns and generate new, original content based on that data. For example:

• Chatbots (like ChatGPT) generate responses to user queries based on context, offering personalized conversations.
• DALL-E generates images from textual descriptions, producing original artwork based on the input it receives.

In contrast, agentic AI is focused on autonomous action to achieve specific goals. While generative AI creates content, agentic AI is designed to take actions and make decisions that move toward an objective. It perceives its environment, reasons about the best course of action, and carries out tasks to achieve goals without needing constant human supervision. Examples include:

• Autonomous vehicles that navigate roads, avoid obstacles, and make driving decisions based on real-time data to get from one location to another.
• Predictive maintenance systems in factories that detect wear on machinery and schedule repairs automatically, preventing downtime.
