What Are the Components of an AI Agent?
AI agents vary in implementation but tend to have five components:
- Agent-centric interfaces, including the protocols and APIs used to connect agents to users, databases, sensors, and other systems, allowing intelligent software agents to observe their environment.
- A memory module includes both short-term memory for recent events and immediate context as well as a long-term memory for factual knowledge, concepts, details of past conversations, and knowledge of how past tasks were performed.
- A profile module defines the agent’s attributes, such as its role, goals, and behavioral patterns.
- A planning module, which typically uses an LLM or SLM, takes observations from the environment, including memory and the agent’s profile, to assemble appropriate plans for an agent to take.
- An action module comprises the APIs and system integrations that define the universe of actions available to the AI agent.
What Do AI Agents Do?
AI agents represent a new era in artificial intelligence, far surpassing traditional software. Unlike static tools, these intelligent software agents act as autonomous, decision-making entities. They analyze data, plan tasks, take action, and continuously adapt—often in real time. Here’s what makes them so powerful:
- AI agents don’t just respond to instructions—they have initiative. They engage with their environment, learning and adapting as they go. AI agents continually collect information from a variety of sources. They use memory and specialized tools to understand what’s happening in their environment and to keep track of important details.
- AI agents decide on the best course of action by considering goals, roles, and constraints. They can update their plans in real time as things change, making them more adaptable to process change and edge cases than techniques like robotic process automation.
- AI agents get things done by using connected systems and collaborating with other intelligent agents.
- AI agents are designed to be active participants in workflows. They’re not just tools—they’re capable, high-performing teammates that bring real value to the teams they support.
What Are the Types of AI Agents?
AI agents vary in complexity, from simple coding assistants to complex networks that can automate processes that require teams of people today. Using coding as an example, we can see the different levels of sophistication that can be achieved with various types of intelligent agents:
- At the simplest level, a coding copilot can generate code when prompted by a developer.
- A more advanced intelligent agent could automatically ingest the existing code base and customize its output appropriately. This agent could even produce output without being asked by automatically producing code that passes a unit test once a developer writes that test.
- Still more advanced AI agents could not only develop code but also compile and run the application in a test environment.
- Future AI agents may take this a step further and deploy tested applications to production environments via automated pipelines upon human approval. This would effectively allow anyone, using plain language, to create and deploy entire applications.
How Do You Use AI Agents?
Strong AI agent performance comes from closely mimicking the processes that humans follow. This is because LLMs, the core planning component of modern agents, are able to “inherit” human cognition—they are trained on a large body of human output and hence can solve problems that are similar to what people can solve.
Like LLMs, virtual agents in AI perform well on problems that can be broken down into component parts. They need small, well-defined tasks. They need relevant context. And they perform even better when tight feedback loops are in place so errors can be corrected upon iteration.
AI agents deliver business value in three main areas:
- Automation of standardized business processes: AI agents can handle repetitive tasks with accuracy and speed, reducing human error and enabling employees to focus on higher-value work.
- Collaboration with humans: Acting as intelligent collaborators, virtual agents in AI enhance human teams by providing actionable insights, supporting decision-making, and executing tasks that augment human expertise.
- Uncovering data insights: In data-rich environments, AI agents analyze and synthesize information at a scale no human team could match, identifying patterns and delivering insights that drive strategic decisions.
How Are Businesses Using AI Agents Today?
AI agents are fast becoming common across industries. Early adopters have already unlocked value from these intelligent software agents in multiple functions, including marketing and sales, customer service, R&D, and data and technology. But this is just the tip of the iceberg. Here are a few business cases for AI agents that companies are exploring today:
- Marketing: A leading consumer packaged goods company used intelligent agents to create blog posts, reducing costs by 95% and improving speed by 50x (publishing new blog posts in a single day as opposed to four weeks).
- Customer service: A leading global bank used AI virtual agents to interface with customers, reducing costs by 10x.
- Research and development: A biopharma company used AI agents for lead generation, reducing cycle time by 25% and gaining 35% in time efficiency for drafting clinical study reports.
- Data and technology: An IT department used AI agents to modernize its legacy technologies, increasing productivity by up to 40%.
Are AI Agents the Future?
AI agents are gaining traction quickly across an array of business applications—and the market for AI agents is expected to grow at a 45% CAGR over the next five years.
