Agentic AI Architecture – How It Works

 

🚀 Introduction

Agentic AI systems are built using a structured architecture that enables autonomous decision-making.

---

🏗️ Core Components

✅ 1. Perception Layer

• Collects data (APIs, sensors, inputs)

---

✅ 2. Reasoning Engine

• Processes data
• Makes decisions

---

✅ 3. Goal & Planning Layer

• Defines objectives
• Breaks tasks into steps

---

✅ 4. Action Layer

• Executes tasks (API calls, automation)

---

✅ 5. Learning Layer

• Improves using feedback

---

🔄 Architecture Flow

Environment → Perception → Reasoning → Planning → Action → Learning

👉 This continuous cycle enables autonomy 

---

🤖 Multi-Agent Systems

Agentic AI can include multiple agents:

• ✅ Single agent → works independently
• ✅ Multi-agent → collaborate on tasks

Example:

• Agent A → data collection
• Agent B → analysis
• Agent C → execution

---

🎯 Conclusion

Agentic AI architecture enables: 👉 Intelligent, scalable, and adaptive systems

💻 ✅ 1. Full Agentic AI Architecture (Single Agent)

class AgenticAI:

    def __init__(self):

        self.memory = []

    # 1. Perception Layer

    # 2. Reasoning Engine

    def reason(self, data):

        print("🧠 Reasoning: Analyzing data...")

        best_option = min(data["options"])

        return best_option

    # 3. Goal & Planning Layer

    def plan(self, best_option):

        plan_steps = [

            "Compare prices",

            "Select lowest price",

            "Prepare purchase"

        ]

        return plan_steps

    # 4. Action Layer

    def act(self, best_option):

        print(f"⚡ Action: Buying product for ${best_option}")

    # 5. Learning Layer

    def learn(self, result):

        self.memory.append(result)

        print("📈 Learning: Updated memory →", self.memory)

    # Full Architecture Flow

    def run(self):

        data = self.perceive()                 # Perception

        best = self.reason(data)               # Reasoning

        steps = self.plan(best)                # Planning

        self.act(best)                         # Action

        self.learn({"result": best})           # Learning

# Run single agent

agent = AgenticAI()

agent.run()

🤖 ✅ 3. Multi-Agent System Example

👉 Matches your handwritten section:

• Agent A → Data Collection
• Agent B → Analysis
• Agent C → Execution

# Multi-Agent System Example

# ----------------------------

# Agent A: Data Collection

def agent_A():

    data = [500, 300, 400]

    print("Agent A (Data): Collected →", data)

    return data

# Agent B: Analysis

def agent_B(data):

    best = min(data)

    print("Agent B (Analysis): Best →", best)

    return best

# Agent C: Execution

def agent_C(best):

    print(f"Agent C (Execution): Purchased item for ${best}")

# Multi-agent flow

def multi_agent_system():

✅ Here’s the clean code representation for your handwritten notes:

👉 Generative AI vs Agentic AI (Think vs Act logic)

---

💻 ✅ Code Example: Generative AI vs Agentic AI

---

🚀 1. Generative AI (Only Responds)

Python

# Generative AI → responds to prompt

def generative_ai(question):

if "flight" in question.lower():

return "The cheapest flight is $300 with Airline B"

else:

return "Here is your answer"

# Example usage

result = generative_ai("What is the best flight?")

print("Generative AI Output:", result)

👉 Output:

Generative AI Output: The cheapest flight is $300 with Airline B

✅ Behavior:

• Takes input
• Returns answer
• ❌ No action performed

---

🤖 2. Agentic AI (Thinks + Acts)

Python

# Agentic AI → completes the full task

def agentic_ai(goal):

print("Goal:", goal)

# Step 1: Search (Perceive)

flights = [

{"price": 500, "airline": "A"},

{"price": 300, "airline": "B"},

{"price": 400, "airline": "C"}

]

print("Searching flights...")

# Step 2: Compare (Reason)

cheapest = min(flights, key=lambda x: x["price"])

print("Comparing options... Best found:", cheapest)

# Step 3: Book (Act)

print(f"✅ Booking flight with {cheapest['airline']} for ${cheapest['price']}")

return "Flight booked successfully"

# Example usage

result = agentic_ai("Book me the cheapest flight")

print("Agent Output:", result)

👉 Output:

Goal: Book me the cheapest flight
Searching flights...
Comparing options...
✅ Booking flight with B for $300
Agent Output: Flight booked successfully

✅ Behavior:

• Finds data
• Makes decision
• Executes action
• Completes task

---

🔁 3. Add Feedback Loop (Agent Learning)

Python

# Adding learning capability

def learn(success=True):

if success:

print("✅ Learning: Task completed successfully")

else:

print("❌ Learning: Improve next time")

# Example

learn(success=True)

---

📊 4. Compare Both Systems in Code

Python

def compare_ai():

print("\n--- Generative AI ---")

print(generative_ai("What is best flight?"))

print("\n--- Agentic AI ---")

agentic_ai("Book me cheapest flight")

compare_ai()

---

🧠 What This Code Shows

Feature	Generative AI	Agentic AI
Input	Prompt	Goal
Output	Answer	Action
Execution	❌	✅
Autonomy	Low	High

---

🔥 Core Logic from Code

👉 Generative AI:

Python

input → output

👉 Agentic AI:

Python

goal → search → reason → plan → act → learn

---

🎯 Final Interview Explanation

👉 Say this:

“In this example, Generative AI simply responds with an answer, while Agentic AI executes multiple steps such as searching, analyzing, and booking—demonstrating autonomous task completion.”
