In other words, they’ve brought intelligence to the fingertips of software developers, democratizing access to AI across industries and applications.

Definition of an AI agent

Fundamentally, AI agents are designed to mimic intelligent behavior by having the ability to make decisions, perform tasks, and interact with their environment. A type of AI agent that plays a critical role in an intelligent system are reactive agents. These agents:

• Perceive dynamic conditions in the environment
• Take action to influence those conditions
• Select actions according to a preference for each state
• Improve their behavior through logical reasoning and reinforcement learning

This decision-making process is unique to reactive agents and is a key characteristic of goal-based agents.

Perceiving the environment isn’t just a feature of AI agents, but a fundamental aspect of their functionality. For model-based agents, a type of AI agent, this perception enables them to collect data and convert it into internal representations, which are essential for decision-making. Without this sensory perception, an AI agent would be akin to a car without a driver—unable to navigate or make sense of its surroundings.

The evolution of AI agents

A look at the past is often required to comprehend the present. This is true of AI agents, or software agents, which have a rich history dating back to antiquity with myths of artificial beings and culminating in 1955 with the development of the first AI program, the Logic Theorist, by Allen Newell and Herbert A. Simon. The goal of AI agents is to emulate the decision-making capabilities of a human agent, a thread that has remained constant since its inception.

Over the years, AI agents, also known as intelligent agents, have swiftly evolved from specific applications, such as game-playing bots, to intricate systems capable of intelligent automation. Key advancements include expert systems, machine learning, and artificial neural networks, propelling AI agents into an era of unprecedented possibilities and potential.

Categories of AI agents

Upon closer examination, AI agents fall into four primary categories, determined by their abilities and intelligence:

1. Reflexive agents: These agents adhere to predetermined rules and make decisions solely based on the present circumstances, without considering the history of prior actions.
2. Goal-oriented agents: These agents have a specific goal or objective and take actions to achieve that goal.
3. Utility-driven agents: These agents make decisions based on a utility function, which assigns values to different outcomes or states.
4. Learning agents: These agents are capable of learning from their experiences and improving their performance over time.

Conversely, goal-oriented AI agents:

• Plan and execute a sequence of actions
• Achieve specific objectives
• Illustrate competence in autonomous decision-making scenarios
• Necessitate achieving well-defined goals.

Utility-driven AI agents, also known as utility-based agents, determine their actions by aiming to maximize a utility function, a metric for their performance objectives. They are commonly utilized in industries such as energy, customer service, and autonomous vehicles.

The final category, learning agents, stand out due to their capacity to adjust and alter their behavior by leveraging past experiences, utilizing their learning capabilities to continuously enhance their performance over time.

Reflexive agents

Reflexive agents, including simple reflex agents, operate by making decisions solely based on the current percept, without taking into account the percept history. They respond to changes in the environment by identifying a rule that matches the current situation and then carrying out the action associated with that rule. An example of reflexive agents in action is a temperature-controlled room equipped with an automated AC system, or a Mars rover that adjusts its course to avoid obstacles based on its current perception.

While reflexive agents, including model-based reflex agents, are effective in their simplicity, they do have their limitations. They are highly dependent on the visibility of the environment and can fall into infinite loops in partially observable environments. Furthermore, they lack memory or state, meaning they can’t retain past states or actions, which can hinder their decision-making in complex or changing environments.

Goal-oriented agents

Goal-oriented AI agents operate with a sense of purpose, strategizing and implementing a series of actions to achieve precise objectives. These agents demonstrate autonomy and a capacity for decision-making, making them the epitome of rational agents. They initiate from an initial state and execute actions to attain a state that fulfills the goal. To optimize their decision-making processes, goal-oriented AI agents utilize LLMs for planning, learning, and decision-making, and adhere to the objectives programmed into the agent or acquired from the data.

The process of achieving tasks for these agents is unique. They obtain intrinsic utility upon goal fulfillment and may experience intrinsic disutility if the goal is unmet. Additionally, they are programmed to pursue their own objectives and optimize their own utility.

Utility-driven agents

Utility-driven AI agents are unique in their operational mechanism. They are designed to maximize a particular utility or decision by using a utility function. In other words, they aim to optimize their performance objectives, making decisions that maximize the outcome of a specific metric.

Utility-driven agents are commonly utilized in fields that require the optimization of resources. Industries such as energy, customer service, and autonomous vehicles often employ these agents to manage resources efficiently and make decisions that maximize beneficial outcomes through their agent function.

Learning agents

Learning agents bring a unique characteristic to the AI agent landscape—the ability to learn. Unlike other agents that operate based on pre-defined rules or objectives, learning agents have the capacity to adjust and alter their behavior by leveraging past experiences. They use their learning capabilities to continuously enhance their performance over time, essentially learning from their mistakes and successes.

Learning agents have found use in a variety of real-world scenarios, including:
