Understanding agentic AI architecture

Summary

Agentic architecture is the structural design and framework for an AI system that allows one or more AI agents to operate autonomously.

• Unlike nonagentic systems that provide simple, linear responses, agentic architectures support dynamic, multistep processes where agents can adapt to new information and learn from outcomes.
• Architectures range from single-agent systems to complex multiagent patterns, which are being applied to transform use cases like workflow automation, customer service and enterprise intelligence.

Key concepts of agentic architecture

Several core concepts define an agentic architecture and separate it from simpler AI models.

• Autonomy: Agents can operate and make decisions with a significant degree of independence, without requiring constant human input for every step.
• Adaptability: The system is designed to adjust its behavior and strategies in real time in response to new information or changing environmental conditions.
• Goal-oriented: The architecture is built to pursue specific objectives. All planning and actions are aligned with achieving a defined end goal, rather than just executing a command.
• Sense-plan-act cycle: This is the fundamental operational loop of an agent. The agent perceives its environment (senses), formulates a strategy (plans) and then carries out that strategy (acts).

The core components of an agentic system

Agentic architectures are typically composed of several integrated layers or components that work together to enable autonomous action.

Perception layer

This is how the agent "senses" its environment. It is responsible for gathering information through various inputs like APIs, user queries or document data.

Reasoning and planning layer

This layer processes information gathered by the perception layer, using large language models (LLMs) to understand semantics, meaning, context and goals. This capability allows the agent to reason autonomously to break down complex problems and create a strategic plan.

Unlike early AI agents that were limited by pre-programmed rules, LLM-powered agents can also reflect on their actions. By analyzing the results and feedback from the action layer, the agent can improve its performance, correct its course and adapt its strategy to achieve better outcomes.

Action layer

This is how the agent "acts" on the world. It executes the plan by using tools, calling APIs, generating text or interacting with other systems.

Memory

This component enables the agent to store and retrieve information efficiently.

Short-term memory manages data for the immediate task, maintaining the necessary focus during execution. Long-term memory builds context over time by extracting and remembering user preferences and summarizing past experiences. This allows the agent to retrieve relevant history to inform the current context, generating a positive bias that helps it successfully resolve new problems.

How agentic architecture works: The sense-plan-act cycle

The operational flow of an agentic system follows an iterative cycle of sensing, planning and acting.

Sense

The process begins when the agent gathers data from its environment. For example, a customer service agent receives a support ticket containing unstructured text.

Plan

The agent uses its reasoning layer to analyze the ticket and formulate a strategy for resolution. For well-defined problems, this can involve creating a complete execution plan with a sequence of sub-tasks, such as identifying the product issue and then searching the knowledge base.

Alternatively, to allow for greater autonomy and flexibility, the agent may focus only on determining the single next best action. After executing that step, it senses the outcome and re-evaluates its plan, adapting its approach based on the new information it receives.

Act

Next, the agent executes the plan using its tools. This process is often governed by modern frameworks like the Model Context Protocol (MCP), which enables the agent to select the right tool and correctly structure its command. For example, it might call a database API to search the knowledge base, then use its text generation capability to draft a reply.

Reflect and iterate

The cycle does not end with action. The agent can then reflect on the outcome. If the knowledge base search returns no results, it can adapt its plan — perhaps by rephrasing the query or deciding to escalate to a human. This iterative loop is what makes the architecture truly agentic.

Agentic vs. nonagentic architecture: From static responses to dynamic action

The distinction between agentic and non-agentic systems lies in their fundamental design and capabilities. A nonagentic architecture enables a linear, "single-shot" process where an input is given to an LLM and a static output is generated. It is suitable for known, well-defined tasks but cannot perform multi-step actions without being reprompted for each step.

The key limitation is its lack of autonomy. While feedback loops can be engineered to create more complex workflows, this results in a sophisticated process, not an autonomous entity. The system lacks the agency to adapt or be flexible, and its performance will always be limited by how that process was originally modeled.

In contrast, an agentic architecture supports an autonomous process. The agent can make multiple decisions, use various tools, and self-correct within a single request to achieve a complex goal, making it essential for dynamic tasks like workflow automation or interactive problem-solving.

Common types of agentic architectures

The complexity and design of an agentic architecture depend on the task it needs to perform.

Single-agent vs. multiagent systems

A single-agent architecture features one autonomous agent making centralized decisions, which is best for focused, self-contained problems.

A multiagent architecture involves multiple agents collaborating to solve a problem, which is better for complex challenges requiring diverse expertise.

Multiagent architectural patterns

Vertical (hierarchical) architecture: A "leader" agent oversees and delegates subtasks to specialized "worker" agents. This is efficient for sequential workflows with clear accountability.

Horizontal (collaborative) architecture: A decentralized model where agents work as peers, sharing information and making decisions collectively. This is ideal for brainstorming or complex problem-solving.

Hybrid architecture: This model combines both vertical and horizontal structures, offering a balance of structured oversight and creative flexibility.

Designing effective agentic architecture

Building a robust agentic architecture requires careful consideration of several key design principles.

Determine the decision-making logic

Decide if the agent needs simple rule-based logic, probabilistic reasoning from an LLM, or reinforcement learning to improve over time.

Define memory requirements

Determine if the agent will be stateless for transactional tasks or if it needs to remember past interactions using short-term state or long-term databases.

Plan for tool integration

Define how the agent will interact with the outside world, whether with a fixed set of tools or the ability to dynamically select tools based on the task.

Manage the solution space

For complex tasks, use domain-specific rules or heuristics to guide the agent and prevent it from getting stuck in inefficient loops.

Establish human supervision

Designing an effective agentic architecture involves balancing agent autonomy with human oversight.

For high-stakes or sensitive tasks, you can build in checkpoints where a human must approve an agent’s plan before it proceeds. For low-risk processes, agents can be granted full autonomy. A hybrid approach is also possible, where an agent operates independently unless its confidence in an outcome falls below a certain threshold, at which point it escalates for human review.

Agentic architecture use cases

Agentic architectures are being deployed to solve real-world business challenges and unlock new opportunities for automation and intelligence.

Complex workflow automation

These systems can automate multi-step business processes like invoice approvals or employee onboarding, where an agent must interact with multiple systems like an HRIS, ERP and email.

Advanced customer service

An agentic system can handle an entire customer issue, from understanding the initial query to searching knowledge bases, interacting with order systems and escalating to a human agent with a complete summary.

Enterprise intelligence and research

Agents can perform deep research tasks by scouring internal databases and external sources, synthesizing information, identifying trends and generating detailed reports.

Autonomous IT operations

A cybersecurity agent can monitor network traffic, detect a threat, plan a mitigation strategy like isolating a server and execute it, all while documenting its actions for an audit trail.

Hyland’s approach focuses on solving complex, content-based problems. To succeed, agents must navigate and understand vast amounts of structured and unstructured information, such as contracts, reports and customer emails. Understanding this content in its full business context is what enables agents to make the best decisions.
