The landscape of artificial intelligence (AI) is undergoing a significant transformation, moving beyond traditional chatbots. Following the launch of ChatGPT in late 2022, which utilized large language models (LLMs), the spotlight is now on action-driven AI agents. While AI chatbots like ChatGPT and Google’s Gemini excel in processing text and visual inputs with natural language responses, AI agents can execute intricate tasks. In this article, we will explore the workings, classifications, and future of AI agents in detail.
Understanding AI Agents: What Are They?
The term ‘AI Agent’ denotes an AI-powered software system capable of planning, reasoning, making decisions, and executing multi-step actions autonomously to achieve specific goals. Unlike AI chatbots, which operate within a confined environment, AI agents engage with external systems to fulfill tasks.
Powered by large language models (LLMs), these AI agents are tailored to facilitate action-driven tasks. Currently, pioneering companies are implementing reinforcement learning and advanced reasoning techniques on visual language models to enhance the functionality of AI agents. Additionally, these agents are often integrated with various external tools, including APIs, functions, and databases, to perform a wide array of tasks effectively.
Therefore, AI agents represent not just a model, but a comprehensive ‘AI system’ that supports tool interaction, manages long and short-term memory, and engages with third-party systems to accomplish designated tasks. A prime example is the Operator AI agent from OpenAI. This Computer-Using Agent (CUA) can navigate graphical user interfaces (GUIs) to perform various online actions.
The Operator AI agent can execute tasks such as browsing the web, ordering groceries, completing forms, and booking flights. Utilizing GPT-4’s vision capabilities, it analyzes screens and determines appropriate clicks. However, it is not yet fully autonomous, sometimes requiring human oversight to resolve loops it encounters.
Given its nascent stage, critical operations such as payment completion revert control to the user. In essence, following the evolution of AI chatbots, we are witnessing the rise of action-driven AI agents capable of performing significant tasks.
Diverse Types of AI Agents: A Detailed Overview
In their seminal work, ‘Artificial Intelligence: A Modern Approach,’ Stuart Russell and Peter Norvig outline five main types of AI agents: Simple Reflex Agents, Model-Based Reflex Agents, Goal-Based Agents, Utility-Based Agents, and Learning Agents.
A Simple Reflex Agent operates on basic conditional logic, reacting to specific stimuli without retaining past information. This fundamental form of AI performs actions when certain conditions are met, lacking memory and learning capabilities.

Conversely, Model-Based Reflex Agents maintain memory and develop a basic understanding of their environment by observing responses to their actions. For instance, a robot vacuum cleaner adapts its internal model to avoid obstacles while cleaning, although its functionality is limited by predefined rules.
Goal-Based Agents focus on achieving specific objectives rather than adhering strictly to rules. This category includes planning and reasoning capabilities, enabling them to evaluate multiple factors before making decisions. A chess-playing AI, for instance, analyzes numerous potential moves to secure a favorable outcome.
Utility-Based Agents are designed to choose action sequences that maximize satisfaction, guided by a reward system. Lastly, Learning Agents possess the ability to acquire new knowledge from unfamiliar environments, improving their performance over time and adapting to user preferences.

Noteworthy Examples of AI Agents in Action
One notable example is OpenAI’s Operator (visit), a groundbreaking consumer AI agent capable of navigating the web through a cloud browser to perform various tasks. Users can request the Operator to order food, book hotels, secure concert tickets, and more. Currently in early research preview, this agent is exclusive to ChatGPT Pro subscribers at a monthly fee of $200 (approximately €190).

In addition to Operator, OpenAI has introduced the Deep Research AI agent, capable of producing comprehensive reports on any subject while providing citations for source verification. Gemini’s Deep Research AI agent offers similar functionalities and is freely accessible.
Anthropic has developed the Computer Use AI agent, which can operate a computer by visually analyzing the screen. Having tested this AI agent within a Docker environment, I found it functional albeit slow. Notably, Anthropic’s MCP standard is gaining traction among AI companies like Google, OpenAI, and Microsoft, facilitating connections between AI agents and AI models.

Recently, Manus, a general AI agent from China, gained attention for its ability to browse the web, execute code, and engage with cloud computers. While its demos have captured interest, it is powered by Anthropic’s Claude 3.5 Sonnet model.
Meanwhile, Google is developing Project Mariner, intended to perform tasks within the Chrome browser, akin to OpenAI’s Operator. Currently, Google is conducting tests with trusted testers, with a release anticipated in the near future.
In conclusion, we are on the brink of the agentic AI era, although full automation and trust in AI models for critical tasks remain a year or two away. Companies are implementing human oversight as the standard for interacting with AI agents. Nevertheless, the future is set to highlight action-driven advancements, with major AI labs like OpenAI and Google DeepMind striving to turn the vision of agentic AI into reality.
