Last update: 05/06/2025

Agentic AI is the next big thing in the evolution of artificial intelligence, where automation is taken to the next level. But not all agentic AI systems are built the same. In this post, we’ll break down the different types of agentic AI agents, explain how they work, and show real-world examples to bring each one to life.

1. What is agentic AI?

Agentic AI refers to a new class of intelligent systems designed to operate with a high degree of autonomy. Unlike traditional AI, which often waits for user prompts or depends on strict programming, agentic AI takes initiative. It can assess situations, make decisions, and take action on its own to achieve specific goals.

Agentic AI systems function more like digital agents than tools. They combine context awareness, reasoning, and learning to navigate dynamic environments, break complex tasks into manageable steps, and adapt as conditions change. From virtual assistants and workflow automation to self-driving cars, agentic AI is already powering a shift toward smarter, more proactive technology.

2. Types of agentic AI agents

When it comes to the question “What are the types of agents in AI?”, we can categorize them based on their architectures, decision logics, and functional roles.

Types of agentic AI architectures

At the heart of every agentic AI system lies its architecture - the structural design that determines how agents think, collaborate, and execute tasks. Broadly, agentic AI architectures fall into two main categories: Single-agent architectures and Multi-agent architectures. In other words, they’re recognizable based on number of agents. Let’s break down what each of these looks like in action.

Types of agentic AI architectures

Single-agent architectures

A single-agent architecture is the most straightforward model. It features one autonomous AI agent operating independently, making decisions and taking actions without needing to coordinate with other agents. This setup is ideal for focused, self-contained tasks - like basic customer service or making personalized recommendations - where collaboration or cross-domain communication isn't necessary. 

However, if you’re trying to handle a high volume of tasks or need your AI to juggle multiple roles, a single agent can quickly become a bottleneck. It’s also not well-suited for complex workflows that require different types of expertise or coordination.

Multi-agent architectures

In contrast, multi-agent architectures introduce a team-based structure - where multiple agents collaborate, each with specialized roles. This setup boosts flexibility, scalability, and intelligence, making them a valuable tool for solving complex problems that span multiple domains, like managing a dynamic supply chain.

Multi-agent architectures come in three main sub-types:

  • Vertical AI architectures: This is a hierarchical structure where a lead agent delegates tasks to sub-agents and oversees the process. Think of it like a manager and their team: roles are clearly defined, tasks flow top-down, and the leader ensures everything aligns with the broader goal. It's ideal for workflows that require approvals or sequential execution, such as multi-step document generation or enterprise automation.
  • Horizontal AI architectures: In this peer-based model, agents collaborate as equals. There’s no central leader - just a group of smart agents working together, sharing knowledge, and collectively making decisions. This architecture is great for brainstorming, creative exploration, and solving open-ended problems that benefit from diverse perspectives and parallel thinking.
  • Hybrid AI architectures: Hybrid architectures bring the best of both worlds. Leadership is flexible - shifting based on the task at hand - and collaboration is dynamic. This makes it well-suited for more complex scenarios where you need both structure and adaptability, like strategic planning or multi-phase product development. It’s powerful but can be more demanding in terms of system design and resource management.

7 types of agentic AI agents by decision logic

Simple reflex agents

Simple reflex agents are the most basic form of agentic AI. They operate entirely on predefined if-then rules, reacting to specific conditions in the environment without any awareness of past events or future implications. Think of them as smart, automated responders: when a trigger appears, they fire off a fixed response - no learning, no memory, just direct execution.

These agents are ideal for predictable, rule-based environments where tasks are clearly defined. You’ll often find them behind things like automated alerts (“If CPU usage > 90%, send a notification”), thermostat controls, traffic lights, or even email autoresponders. While they don’t adapt or evolve, their reliability makes them perfect for repetitive, well-scoped tasks.

Simple reflex agents

Model-based reflex agents

Model-based reflex agents take reactive operations a step further with an internal model of the environment. While they still respond to conditions as they arise, they can “remember” what has happened before and use that memory to make more context-aware decisions.

Picture a marketing AI that doesn’t just flag a drop in ad performance - it recalls that a similar dip followed a budget shift last quarter. That added context makes its alert smarter and more relevant.

Model-based reflex agents are useful in scenarios that require situational awareness over time, like tracking trends, managing inventory, or detecting changes in customer behavior. In industries like banking or logistics, these agents help by factoring in past states (e.g., a customer’s profile history or inventory trends) to trigger more accurate responses.

But while they’re better at navigating partially observable or evolving environments, model-based reflex agents still don’t plan ahead or set long-term goals.

Goal-based agents

Goal-based agents act as strategists. They use internal models of their environment and actively pursue specific objectives, choosing actions based on how well they move toward a defined outcome.

Unlike reflex agents, which respond to conditions as they happen, goal-based agents evaluate multiple paths and select the one most likely to get them closer to their goal. For example, in logistics, a routing agent might assess time, distance, and traffic to find the most efficient delivery route. In marketing, a goal-based agent might test different ad strategies to optimize for a target CPA.

These agents are great for scenarios that involve planning, experimentation, or prioritizing trade-offs, such as budget allocation, forecast adjustments, or predictive process routing. They’re especially useful in dynamic environments where several possible actions might lead to the same goal - some better than others.

That said, they’re not flawless. A goal-based agent might chase an outcome through any available route, even if it’s not the smartest or most ethical option. Without extra layers of reasoning or constraints, they'll focus purely on outcome over method.

Utility-based agents

Utility-based agents bring decision-making to a more sophisticated level. Instead of just chasing a goal, they ask a deeper question: Which outcome is the most valuable? These agents weigh the pros and cons of different actions using a utility function - a kind of scoring system that reflects preferences like cost-efficiency, speed, quality, or risk.

For example, in marketing, a utility-based agent might simulate multiple campaign strategies and select the one that best balances ROI, brand impact, and budget constraints. 

This makes them ideal for multi-objective decision-making, like dynamic pricing, portfolio optimization, or smart resource allocation. They’re built to handle complexity, trade-offs, and uncertainty far better than simpler agent types.

However, there’s a catch: their performance depends heavily on how well the utility function is defined. If you can’t clearly articulate what “best” means in a given context, the agent might optimize for the wrong thing - or make decisions that miss the bigger picture.

Utility-based agents

Learning agents

Learning agents are the adaptive powerhouses of agentic AI. Unlike other types of agentic AI agents that rely on fixed rules or predefined models, these agents evolve over time, improving their performance based on experience, feedback, and interaction with the environment.

They learn what works - and what doesn’t - by analyzing patterns in data and adjusting their strategies accordingly. For example, a recommendation engine  refines product suggestions based on what users actually click, while a smart marketing agent might tweak bidding strategies in real time based on campaign performance.

At their core, learning agents often include components like:

  • A performance element that makes decisions,
  • A learning element that updates knowledge,
  • A critic that gives feedback (e.g., rewards or penalties),
  • And a problem generator that explores new ways to improve.

These agents excel in complex, changing environments, but they also come with trade-offs. Learning agents require high-quality data, computational resources, and time to train effectively. Plus, their decision-making process can be hard to interpret - what’s often called a black box problem. That opacity can make some business stakeholders uneasy, especially when trust and traceability are key.

Multi-agent systems (MAS)

Multi-agent systems bring everything together - literally. These are systems where multiple AI agents work in tandem, either collaboratively or competitively, to tackle complex tasks that are too big for one agent alone.

Each agent in the system might specialize in a specific function, but together, they form a coordinated network that shares information, delegates responsibilities, and dynamically adapts to the environment. Think of it like an orchestra: each instrument (agent) plays its part, but the magic comes from how they harmonize.

In real-world applications, MAS are a natural fit for environments where tasks are interconnected and constantly changing. For example, in smart factories, a layered MAS might include reflex agents handling machinery safety, model-based agents monitoring wear and tear, and goal- or utility-based agents optimizing for cost or speed - while learning agents continually improve operations from past performance.

Multi-agent systems

Hierarchical agents

Hierarchical agents are structured systems of AI agents that operate across different levels of abstraction. Think of them as an organizational chart for intelligence: higher-level agents focus on strategic goals and decision-making, while lower-level agents execute specific, tactical tasks.

This top-down structure allows complex problems to be broken down efficiently. A high-level agent assigns subtasks to lower-level agents, which handle execution and report back. The upper layer then integrates these results, adapts strategies if needed, and continues coordination - much like a manager delegating work to a team and then steering the overall project based on progress.

These agents often combine different agent types - reflexive, goal-based, utility-based, or learning - depending on what each layer needs. Some use simple, fast-acting rules at the bottom and more sophisticated reasoning at the top. For example, in an ecommerce system, individual product recommendation agents work under a broader orchestration layer that adjusts promotional strategy based on seasonal goals or customer behavior patterns.

6 types of agentic AI agents by Functional Roles

Customer agents

Among agent types in enterprise AIs, customer agents are the most popular. Equipped with natural language processing (NLP), customer agents are designed to engage in human-like conversations - answering questions, solving problems, and guiding users through complex workflows. Unlike traditional chatbots that follow static scripts, customer agents understand context, learn from interactions, and adapt over time.

Example:  Volkswagen partnered with Google’s Gemini to supercharge its myVW app. The result? A virtual assistant that does more than field basic questions. Drivers can ask things like “What does this blinking light mean?” and, using the phone’s camera, the assistant identifies dashboard indicators and explains what’s wrong.

Customer agents

Employee agents 

Think of employee agents as internal helpers with your desk work. They automate the behind-the-scenes tasks that clog up calendars, from managing training schedules to answering HR questions and handling onboarding paperwork. By reducing operational friction, they give employees time back to focus on higher-impact work.

Example: Uber uses this type of agentic AI agents to streamline driver onboarding. Instead of manual data entry and back-and-forth emails, AI agents handle background checks, assign training modules, and resolve support tickets - all automatically. What once took days now happens in hours, boosting both efficiency and the driver experience.

Creative agents 

Need a blog post, product image, or social caption? Creative agents are built for just that. Powered by generative AI, they turn briefs into branded content - including text, visuals, and even video - while staying aligned with tone and voice guidelines.

Example: PUMA uses Google’s Imagen to produce hyper-customized product photos. Instead of relying solely on expensive photoshoots, creative agents generate visuals tailored to local markets and seasonal campaigns. 

Data agents

Data agents thrive in messy, complex data environments. They clean, organize, and analyze data at scale, surfacing patterns and insights far faster than any human analyst could.

Example: A leading financial institution deployed data agents to monitor real-time trading activity. The agents ingest live market data, flag emerging trends, and even forecast volatility patterns - giving traders a valuable edge.

Code agents 

Code agents are like a second set of hands for engineers. They can suggest code completions, fix bugs, optimize logic, and even translate plain English into functional code. These agents supercharge developer productivity, especially in fast-paced environments where speed and quality matter equally.

Example: GitHub Copilot is a real-time code assistant that integrates directly into your IDE. As developers write, Copilot anticipates their intent, suggesting full-line or multi-line code completions. It reduces repetitive grunt work and lets engineers focus on solving actual problems cutting development time while improving code quality.

Security agents 

Security  agents are your AI-powered guardians. They monitor systems continuously, detect anomalies, and respond to threats in real time. They’re trained to recognize suspicious patterns, assess risk, and take action - all at machine speed.

Example:
Microsoft Security Copilot supports cybersecurity teams by analyzing millions of signals across an enterprise’s digital footprint. When a potential breach is detected, the agent flags it, outlines the possible attack vector, and recommends immediate actions.

4. Challenges with using Agentic AI

Although agentic AI holds immense promise, its implementation is not without challenges. Below are the key challenges you need to overcome for effective adoption of agentic AI.

High costs and integration barriers

All types of agentic AI agents require up-front investment - hardware, software, data infrastructure, training, and ongoing maintenance all come at a price. For businesses still reliant on legacy systems, integration can turn into a major bottleneck, demanding re-architecting or third-party tooling just to get things working.

Limited context awareness

Despite their sophistication, agentic AI agents often have a short memory. Their ability to retain and utilize context from earlier conversations or tasks is limited. This makes it harder for them to maintain continuity or understand nuanced instructions over long interactions.

Lack of planning and foresight

Agentic AI agents excel at handling defined tasks - but struggle when it comes to long-term planning, unexpected scenarios, or strategy shifts. They can follow goals, but not necessarily anticipate obstacles or adjust priorities without human help.

Inconsistent and unreliable outputs

Because agentic AI communicates in natural language, it’s prone to what’s often called “hallucination” - generating outputs that sound plausible but are factually wrong or poorly formatted. It can also misinterpret prompts, ignore specific instructions, or introduce inconsistencies.

Prompt sensitivity and engineering gaps

These systems rely heavily on well-constructed prompts to guide their actions. A poorly worded prompt - or one that lacks specificity - can result in incorrect decisions, failed tasks, or even security risks.

Data readiness and quality issues

Agentic AI is only as good as the data it uses. Incomplete, outdated, or biased data can lead to flawed decisions and system failures. Yet ensuring data is clean, compliant, and up-to-date across real-time pipelines is a tall order for most organizations.

Role ambiguity and emotional blind spots

While agentic AI can take on many functions, assigning it to nuanced roles - like customer empathy or leadership support - is still a stretch. These agents struggle with emotional intelligence, moral reasoning, or understanding cultural and human nuances.

Ethical concerns and bias

If trained on skewed or incomplete datasets, agentic AI can reinforce harmful biases. This is especially dangerous in high-stakes areas like hiring, law enforcement, or finance, where biased decisions can have legal and societal consequences.

Security and privacy risks

Agentic AI often accesses sensitive, real-time data - and that makes it a high-value target. Without data security solutions like robust encryption, access controls, and monitoring, the risk of data leaks or unauthorized access grows significantly.

5. Conclusion

Agentic AI is transforming how businesses operate - bringing intelligence, autonomy, and adaptability to roles once limited by manual processes.
