Building a Solid AI-Agent
Architecture: Principles, Models
& Best Practices
By David Malick Dieng
AI agents are the next leap beyond static AI models. Instead of just
responding to prompts, they can perceive, plan, act, and learn—often without
constant human guidance. But the secret to making them truly reliable isn’t
just having a large language model (LLM) at the core—it’s how you design the
architecture around it.
This guide will show you exactly how to architect AI agents that are scalable,
adaptable, and enterprise-ready.
Building a Solid AI-Agent Architecture
From Concept to Scalable Reality How to design AI agents that last, adapt,
and deliver.

Why This Matters
AI agents ≠ just prompts to
ChatGPT
Solid architecture =
stability, scalability,
adaptability
Without it: demos work,
production fails

What Is AI-Agent Architecture?
Definition: The blueprint for how an AI agent:
01
Perceives inputs
02
Plans actions
03
Acts via tools/APIs
04
Learns from feedback

Core Benefits
Modularity
swap parts without re-build
Scalability
grow without chaos
Adaptability
evolve with tech changes
Reliability
consistent performance

Core Components
• Perception Layer → captures input
• Planning Layer → decides next steps
• Memory Layer → stores context
• Tool Layer → executes actions
• Feedback Loop → self-corrects

Architecture Models
Reactive
instant, but shallow
Deliberative
deep thinking, slower
Hybrid
speed + intelligence (best for most)

Agentic / Multi-Agent Systems
Multiple agents, each specialized
Examples: Planner, Researcher, Executor, Evaluator
Orchestrator coordinates
More robust & scalable than single-agent setups

Enterprise-Grade Must-Haves
1 Unified & clean knowledge base 2 Legacy system integration
3 Smart context retrieval 4 Prompt-based adaptability > model
retraining

Best Practices
1
Keep modules swappable
2
Make planning steps
transparent
3
Build graceful error handling
4
Human oversight in critical workflows
5
Full action & decision logging

Future-Proof Design
Think like an app store:
Replace LLM without redesign Plug in new APIs easily Add governance rules without
disruption
