AI Agents vs AI Workflows vs LLMs
A simple, non-technical map of where AI is heading — and why “agentic” is a big deal.
LEVEL 1 LLMs (Chatbots)
What you already use: ChatGPT, Claude, Gemini.
- Great at generating text & ideas.
- No access to your private data by default.
- Passive: waits for your prompt.
LEVEL 2 AI Workflows
LLM + predetermined steps set by humans.
- Follows a fixed path (“control logic”).
- Can call tools like calendar/weather APIs.
- Still needs you to design & fix the path.
LEVEL 3 AI Agents
Goal-driven AI that decides the steps.
- LLM becomes the decision maker.
- Picks tools & order dynamically.
- Self-critiques and improves output.
Two Scary Buzzwords Made Simple
RAG (Retrieval Augmented Generation)
Meaning: AI looks things up before answering.
- Calendar lookup
- Web/news search
- Weather API call
Key point: RAG is a type of workflow step, not an agent by itself.
ReAct Framework
Meaning: Agents must Reason and Act.
- Reason: plan best approach
- Act: use tools to execute
- Observe: check results
- Repeat until goal met
Key point: ReAct = the “brain + hands” cycle of agents.
Real-World Agent Example
Keyword: “Skier” in a video archive.
- Agent reasons what “skier” looks like.
- Scans footage using vision tools.
- Tags likely matches.
- Refines results automatically.
- Returns the best clips — no human labeling needed.
Why Agents Matter Now
- Shift from automating tasks to automating outcomes.
- You give goals — AI figures out how.
- Less workflow-building, more delegation.
“Do this step…” ➜ “Achieve this goal.”
What’s About To Change For You
Creators
- Autonomous research + outlining
- Draft + self-editing loops
- Auto repurposing into reels/posts
- Scheduling & distribution
Professionals & Teams
- Email + calendar management
- Report generation
- Customer support triage
- Sales follow-ups
The fastest winners will be those who learn to supervise agents, not those who only learn to prompt chatbots.
Your Simple 1-2-3 Roadmap
- 1) Master prompts (LLM level): clarity, context, structure, tone.
- 2) Play with workflows: Make.com, Zapier, Notion, Sheets, APIs.
- 3) Think in goals: “achieve outcome” vs “follow steps.”
“Summarize this article.” ➜ “Extract key insights and action items relevant to my project.”
Why agentic AI is the next leap beyond chatbots — and what it means for your day-to-day life.
Artificial Intelligence today feels like a broken record.
Agents. Agentic workflows. Autonomous agents. RAG. ReAct. Multi-step reasoning.
Every company is shouting these words. Every product claims to be “agentic.” Every demo promises a future where AI does everything for you.
And yet, for most people — especially creators, freelancers, founders, managers, and professionals who use AI but aren’t technical — these terms feel slippery. They are either explained in extremely technical language (“vector search across chunk embeddings using self-reflection loops”), or in over-simplified marketing fluff (“AI that works like magic”).
This article is for the vast majority in the middle — smart people who want to understand agentic AI without needing a PhD.
We’re going to decode the entire evolution from:
- LLMs →
- AI Workflows →
- AI Agents
…using real-life examples you’ll actually recognize.
This is not a hype piece. It’s a practical, grounded guide to what’s happening right now — and how it will transform your productivity, business, and career sooner than you think.
Let’s begin at the beginning.
LEVEL 1 — LLMs: The Chatbot You Already Know
Large Language Models — ChatGPT, Claude, Gemini — exploded because they made advanced AI feel simple.
You type a request.
The model generates an answer.
Input → Output.
Question → Response.
Prompt → Text.
This is the mental model we all started with.
A simple example
You tell ChatGPT:
“Write an email asking someone for a coffee chat.”
It instantly drafts a polished, friendly message — probably more polite than you would write yourself.
Easy, powerful, magical.
But LLMs have two big limitations:
1. They don’t know your private data.
Ask ChatGPT:
“When is my next meeting?”
It fails — not because it’s stupid, but because:
LLMs cannot access personal or company data unless you connect external tools.
2. LLMs are passive.
They won’t act unless you ask them to.
They don’t:
- look up your calendar
- fetch latest news
- summarize files
- automate tasks
They wait for instructions. They respond. That’s it.
This limitation is exactly why the next evolution began.
Because we don’t just want answers — we want action.
LEVEL 2 — AI Workflows: When You Give AI a To-Do List
Imagine you want an AI to answer questions about your schedule.
You could say:
“Whenever I ask about an event, check my Google Calendar first.”
Now the LLM has a predefined path (control logic):
- Detect if question is about an event
- Look at Google Calendar
- Return the result
This is an AI workflow — also known as an automation, pipeline, flow, or sequence.
Here’s what makes a workflow a workflow:
- You create the steps.
- The steps run in the order you designed.
- AI is not thinking — it is following your instructions.
A real-world example
Suppose you automate your daily social media content:
- Pull links from Google Sheets
- Summarize with Perplexity
- Draft posts using Claude
- Publish at 8 AM
This is powerful — but still not “agentic” because you are the decision maker.
You decide:
- what tools to use
- what steps to run
- what order to follow
- how to fix errors
- how to improve prompts
AI is helping, but it’s still following a rigid script.
So what about RAG?
RAG (Retrieval Augmented Generation) is not magical.
It simply means:
“Before answering, check supporting information.”
Just like “look into my calendar” or “search the weather.”
RAG = a fancy name for a lookup step.
It is still a workflow, not an agent.
Workflows enhanced what LLMs can do — but they created another problem:
The human is still the bottleneck.
We need the next leap.
LEVEL 3 — AI Agents: When AI Becomes the Decision Maker
This is where everything changes.
An AI agent is not a smarter chatbot.
It’s not a longer workflow.
It’s not LLM + steps.
An AI agent is an LLM that:
- reasons
- takes action
- uses tools
- evaluates results
- iterates until the goal is met
The key difference?
In a workflow: YOU decide what happens next.
In an agent: AI decides what happens next.
Let’s break this down using a real case.
THE EXAMPLE: Building Content from News Articles
When you do it manually, you must:
- locate articles
- save links
- summarize content
- write draft posts
- rewrite them
- refine them
- schedule publishing
When it’s an AI workflow, the system:
- pulls links
- summarizes
- drafts
- posts
…but YOU still build and control every step.
When it becomes an AI agent, the LLM decides:
- How to find articles
- Which tool is best
- In what order the steps should run
- Whether the post is good
- How to improve it
- When to stop iterating
This leap in autonomy is what makes agents revolutionary.
THE 3 CORE POWERS OF AI AGENTS
1. Reasoning (Re)
This is the “think” step.
The agent asks:
- What is the best way to achieve this goal?
- What sequence of steps do I need?
- Which tools or data sources should I use?
If one plan fails, it generates a new one.
This is similar to how a human would plan a task.
2. Acting (Act)
The agent uses tools:
- Google Sheets
- APIs
- Browsers
- Calendars
- Databases
- Plugins
- Automations
Think of it as an employee performing actions on your computer — but digitally.
3. Iterating (Self-reflection)
This is what makes agents feel alive.
The agent:
- checks its output
- critiques itself
- identifies errors
- re-runs steps
- improves quality
- tries again
- repeats until the goal is met
This is exactly what humans do when they refine drafts or debug processes.
In fact, this loop is the reason many agents use the ReAct framework:
Reason → Act → Observe → Reflect → Act → Repeat
Human-like problem solving, but automated.
A REAL EXAMPLE — AI Vision Agent
Andrew Ng’s demo is a perfect illustration.
Enter a keyword: “skier.”
The agent:
- reasons: What is a skier? What should I look for?
- acts: scans video clips
- observes: identifies matches
- iterates: refines matches
- returns: the most accurate results
A human editor would need hours to tag videos manually.
The agent does it automatically.
This is not magic — it’s the ReAct loop in action.
The agent:
- forms a hypothesis
- tests it
- self-corrects
- repeats
- delivers
That’s why agents are such a leap beyond workflows.
WHY AGENTS MATTER — AND WHY EVERYONE IS TALKING ABOUT THEM
This is not just a technical shift.
It’s a shift in how work itself is done.
Before agents
We used tools.
During workflows
We automated tools.
With agents
We delegate goals — not tasks.
This is the beginning of a new era where you won’t automate steps.
You will automate outcomes.
You won’t tell AI how to do something.
You’ll tell AI what you want done.
And the agent will figure out everything in between.
THE 3 LEVELS, VISUALLY
LEVEL 1 — LLM
You ask → AI outputs text.
(No reasoning. No actions.)
LEVEL 2 — Workflow
You ask → AI follows your predefined steps.
(Reasoning done by humans.)
LEVEL 3 — Agent
You give a goal → AI figures out the steps, performs actions, evaluates results.
(AI becomes the decision maker.)
WHAT AI AGENTS WILL CHANGE IN THE REAL WORLD
Let’s get practical.
Here’s what agentic AI will disrupt faster than people expect.
1. Personal Productivity
Your AI agent will:
- read your emails
- update your calendar
- prepare agenda notes
- research your questions
- summarize documents
- fill forms
- plan your week
- book appointments
This is no longer sci-fi.
Agents are already capable of many of these tasks.
2. Content Creation
Agents will not just write a blog post.
They will:
- suggest topics
- research supporting points
- outline the article
- write a draft
- critique the draft
- refine tone
- format it
- schedule it for publishing
- create social media snippets
All from a single command like:
“Create and schedule a weekly LinkedIn post based on trending AI news.”
3. Business Operations
Marketing teams will run autonomous agents that:
- monitor competitors
- update dashboards
- draft campaigns
- test A/B variations
- adjust budgets
Sales teams will run agents that:
- qualify leads
- summarize calls
- prepare proposals
- follow up automatically
Support teams will run agents that:
- answer tickets
- escalate cases
- pull customer history
4. Technical Work for Non-Technical People
This is the biggest shift.
Agents will remove the need to:
- write long workflows
- build automations
- understand APIs
- debug scripts
A non-technical manager will soon say:
“Create a weekly report summarizing our metrics and emailing it to my team.”
…and the agent will build the entire pipeline itself.
THE FUTURE: YOU WILL MANAGE AI EMPLOYEES
This is the real implication.
We are moving toward a world where:
- AI agents perform 20–40% of knowledge work
- humans supervise “teams” of agents
- you’ll give goals, not instructions
- agents will collaborate with each other
- workflows will become self-generating
- AI will not just complete tasks — it will run processes end-to-end
This shift is as big as the move from:
- typewriters → computers
- offline systems → the internet
- manual workflows → software
- apps → AI-native systems
We are entering an era where software manages itself.
And people who understand agentic systems — even at a basic level — will have a career advantage similar to early internet adopters.
SO WHAT SHOULD YOU DO NOW?
Here’s a simple roadmap — aligned with the podcast’s 1-2-3 structure.
Step 1 — Master Prompts (LLM Level)
Learn to:
- be specific
- give context
- set structure
- define tone
- give examples
This is your foundation.
Step 2 — Experiment with Workflows
Use tools like:
- Make.com
- Zapier
- Notion
- Perplexity API
- Google Sheets
- Obsidian plugins
- ChatGPT Actions
Build simple automations.
This helps you understand:
- inputs
- outputs
- control logic
- external tools
- data sources
Step 3 — Learn Agentic Concepts
Not coding — concepts.
Understand:
- ReAct framework
- RAG workflows
- tool use
- iteration loops
- goal-based prompting
- self-critique feedback
You don’t need advanced math or engineering.
Just enough to understand how agents think.
Step 4 — Start Delegating Goals (Not Tasks)
This is the biggest mindset shift.
Stop saying:
“Summarize this document.”
Start saying:
“Extract everything relevant to my project goals and prepare action items.”
Stop saying:
“Write a LinkedIn post.”
Start saying:
“Generate a week-long content calendar based on trending AI topics.”
FINAL THOUGHTS: YOU DON’T NEED TO BE TECHNICAL TO WIN IN THE AGENT ERA
The beauty of this new AI wave is that the complexity is hidden.
Just like:
- you use Google without understanding PageRank
- you use Wi-Fi without understanding radio frequencies
- you use a phone without understanding microchips
You will use agents without understanding LLM architecture.
What matters is not coding.
What matters is thinking in goals.
Agentic AI will reshape industries, careers, and creativity.
The people who succeed will be those who learn early how to delegate, supervise, and collaborate with AI systems.
Because the future isn’t humans vs AI.
The future is humans with AI agents — achieving what used to take entire teams.
Welcome to the agent era.
You’re still early.
