What Are AI Agents?

In general, agent means to act on behalf of others. We give artificial intelligence the right to act on behalf of humans and execute tasks autonomously. And we call them artificial intelligence agents or intelligent agents. AI agents are the next big thing for your business operations and business intelligence making your business fully automated.

Artificial Intelligence Agents or Large Language Models (LLM agents) are moving the world around. This is the next article in our Generative AI Wiki series. Go through our glossary to read about other articles.

A software that can communicate with its environment, acquire data, and operate independently based on that data. The software that performs the action to achieve predefined objectives is called an artificial intelligence (AI) agent. An AI agent autonomously determines the optimal course of action to accomplish the goals humans set for it.

Large language models (LLMs) are the building blocks of AI agents. Because of this, AI agents are frequently called LLM agents. Conventional LLMs are limited by knowledge and reasoning constraints and generate their responses depending on the data that was used to train them. On the other hand, agentic technology leverages backend tool calling to acquire current data, streamline processes, and independently generate subtasks to accomplish intricate objectives.

Through this approach, the autonomous agent gradually gains the ability to adjust to user expectations. The agent's capacity to remember previous exchanges and organize actions for the future promotes a customized encounter and thorough responses. This tool calling increases the potential for practical applications of these and can be accomplished without the need for human intervention.

The different components of AI agents are –

Sensors – They act as information gatherer. Anything from camera, microphone, etc. Software agents can take input as a command, or any instruction.

Actuators – They help in carrying out the actions, AI agents want to execute.

Control Systems —The information gathered by sensors is then analyzed by the control system, which is the AI agent's think tank.

Learning Systems – This system learns from the environment to better respond to user queries.

Control systems and Learning systems both form the environment with which the sensors and actuators interact.

AI agents follow a systematic approach from information gathering to execution autonomously.

Due to some similarities like natural language processing for text understanding, LLM-backed output generation AI chatbots are often tagged as AI agents.

However, the basic difference between an AI chatbot and an AI agent is in the core functionality.

AI agents are designed to perform autonomous tasks whereas AI chatbots are designed to interact with human queries.

AI agents are developed to be think tanks and execute tasks autonomously. They don't need to interact with a human necessarily every time. They may occasionally take a task from a developer and do it on their own, working alone without consulting a human.

Talking about chatbots, are often text-based or voice-based. AI agents can find their application in complex domains like robotics, LLMs to regular home chores, like a mundane vacuum cleaner.

AI agents are classified into different types. These are -

These agents search one or a limited group of sensors for a stimulus. When they detect that signal, they evaluate it, make a judgment, and then generate an output or an action. Simple digital thermostats are a basic example of simple reflex agents.

These agents maintain an active internal state, learning about the world and how their actions impact it. Over time, this facilitates better decision-making. Self-driving cars incorporate such agents to make decisions and assess the environment around them.

This type of agent designs a plan of action to address a specific issue. They create a to-do list, start working on it, and assess if their efforts are bringing them closer to their objective. These agents can be found in AI agent apps and even outwitting human chess masters

Agents generate potential choice outcomes when faced with several feasible options. Every option is tested, and its utility function is used to assign a score: Which option is the best deal? The swiftest? The most productive? Extremely helpful in selecting the best option and possibly addressing moments of paralysis by analysis in humans. These are also helpful in smart city traffic management.

As the name suggests, learning agents pick up knowledge from their environment and actions. They use a performance element to decide what to do and how to proceed depending on what they have learned so far, and a problem generator to design tests to explore the world. You can see the spam emails getting filtered. That’s a learning agent at work for you.

Integrating AI agents in your software solutions or domain can enhance your operational efficiency. It is beneficial in different domains reducing the burden on humans. AI agents help humans handle complex tasks.

Real estate incorporates AI agents for virtual touring and other things benefiting the business owners and enhancing their capabilities. It also schedules calls and helps customers with queries.

Siri is yet another much-used AI agent that is used in our households for executing any task ranging from playing a song to maintaining calculations.

Today we are surrounded by AI agents but little do we acknowledge them. They are easily masked under other technologies. For instance, the Google assistant guiding us to the next destination is an AI agent, the self-driving car or driverless car is the smartest AI agent autonomously and successfully executing the operations. Virtual touring call scheduling and assisting real estate business owners is yet another smart and helpful use case of generative AI in real estate. Similarly here are some use cases of AI agents in various other industries apart from real estate -

The most popular and evident use of AI agents has been in Autonomous vehicles like self-driving cars. They are the best examples of AI agents working on autonomous tasks. AI agents are essential to their operation since they sense the surroundings of the automobile and decide whether it is safe to turn or slow down. By taking environmental cues into consideration, they can recognize whether the vehicle is about to approach a stop sign or traverse unfamiliar territory.

Chatbots have proven to be of much use. An AI agent can serve as a customer helper for a business since it can be integrated with company data.

AI agents have a wide range of practical uses in the healthcare industry. In these kinds of situations, multi-agent systems can be especially helpful for solving problems. These solutions free up doctors' time and energy for more pressing duties, such as treating patients in the emergency room or handling medication routines.

Another obvious use of AI agents is in robotics. Robots are the epitome of tech working autonomously. AI implementation in the robotics sector has made it even more exciting. Loosely it can be said that “robots are the personification of AI agents.”

AI agents are a major advancement in the overall story of technological progress. These agents combine artificial intelligence capabilities with human-like decision-making and interaction. It's obvious that AI agents will only become more influential as we approach a new era in which they play a collaborative role in strategic decision-making and customer interaction rather than only being tools. AI agents can propel companies to the forefront of creativity, productivity, and customer satisfaction.
