Key Features
AI agents are reshaping how businesses operate by increasing efficiency and reducing manual effort.
How AI Agents Work: The 4-Step Cycle of Perception, Reasoning, Action, and Learning
AI agents operate through a continuous cycle of gathering data, reasoning, taking action, and learning. This process allows them to work independently and refine their performance over time, making them much more advanced than basic automation tools.
AI agents are built on four essential components that function together to achieve their goals:
Perception This is how agents collect data from their surroundings. They pull information from APIs, web searches, user inputs, and their internal memory. For instance, a customer service AI might analyze previous conversations before crafting a response.
Types of AI Agents
- Reasoning: Here, a large language model (LLM) serves as the agent's "brain." It processes instructions and breaks down complex tasks into smaller, actionable steps, ensuring tasks are tackled efficiently.
- Action: Once a plan is in place, the agent interacts with external tools, such as APIs or databases, to carry out its tasks. For example, it could initiate a refund by triggering a payment API or update stock levels in response to a new order.
- Learning: Agents improve over time by incorporating human feedback and using reinforcement learning techniques to fine-tune their behavior.
These elements work together to form the backbone of an AI agent's functionality.
The workflow begins when a task is assigned, either through a user prompt or an automated trigger. The agent first gathers context by accessing databases or retrieving stored information.
By October 2024, CEO Andy Jassy shared that Rufus had assisted over 250 million customers, with monthly active users increasing by 140% year-over-year.
How AI Agents Work
Main Parts of AI Agents
With the necessary context in hand, the agent plans its approach. Two common planning methods are:
ReAct (Reasoning and Action): The agent alternates between thinking, acting, and observing results, repeating this cycle until the task is complete.
ReWOO (Reasoning Without Observation): In this method, the agent plans the entire process upfront and executes it step by step, which can minimize computational demands.
After planning, the agent executes its tasks using the tools at its disposal. It then evaluates the results and adjusts its approach if needed. This ability to self-correct is what sets AI agents apart as autonomous systems.
"The reasoning layer is a defining feature of agentic AI, enabling agents to think about how they achieve their goals." - NVIDIA
AI Agent Workflow
AI agents can be grouped based on how they make decisions and what drives their objectives. These categories help identify which type of agent fits specific tasks or challenges. By understanding these distinctions, it becomes clearer how different agents enhance workflows and solve problems.
Goal-based agents are all about achieving a specific target. They break down the main objective into smaller, manageable steps and use planning algorithms to determine the most efficient way to complete them. For example, a delivery robot might calculate the quickest route to its destination, or project management software could organize tasks to meet a tight deadline. These agents excel at executing tasks in a step-by-step manner to meet their goals.
Utility-based agents take decision-making a step further by evaluating multiple factors at once. Instead of just aiming for a goal, they assess which outcome offers the best overall benefit, using a utility function to measure factors like rewards or efficiency. A navigation system balancing fuel costs, toll fees, and travel time is a good example. These agents are especially useful when managing trade-offs, such as speed versus safety or cost versus quality. For instance, stock trading bots use this approach to continuously evaluate and maximize returns. This ability to weigh options dynamically makes them highly versatile.
Learning agents are designed to improve over time. They rely on four key components: a learning element to acquire knowledge, a critic to provide feedback on performance, a performance element to make decisions, and a problem generator to test new strategies. Streaming platforms often use these agents to analyze user behavior and refine recommendations. As they gather more data, they become better at predicting user preferences and making smarter decisions.

AI agents are becoming a part of everyday digital life, managing customer inquiries, hosting live shopping events, and producing content on a large scale. Let’s take a closer look at how they’re transforming three major areas.
Online shopping has embraced AI agents to guide customers through every stage of their purchase journey. These agents integrate with product catalogs, inventory systems, and order databases to deliver real-time answers. They tackle complex questions, recommend products based on a shopper’s history, handle returns, and even update shipping details - all without human help.
For instance, Amazon introduced Rufus, an AI shopping assistant, in February 2024. By October 2024, CEO Andy Jassy shared that Rufus had assisted over 250 million customers, with monthly active users increasing by 140% year-over-year. Similarly, Lowe's launched Mylow in March 2024, an AI assistant developed in collaboration with OpenAI. By November 2024, Lowe's CEO Marvin Ellison revealed that Mylow was fielding nearly 1 million questions per month about product details and project advice, easing the workload for human staff.
Utility-Based Agents
