Introduction
At a certain stage, everyone learning artificial intelligence goes through the same frustration:
You understand the theories.
You know what a Transformer is.
You've watched dozens of explanations.
But when you try to build a project…
everything becomes blurry.
Do you need to train a model?
Do you use fine-tuning?
Do you start with RAG or Agents?
And this is where most people get lost.
The truth is much simpler than that:
You don't need a complex project… you need a clear and complete project.

1. Project Idea
The problem is simple:
Long articles take time.
And people want the idea… quickly.
The solution:
An application that allows the user to:
Paste any article
Choose the length of the summary
Get a simplified and easy-to-read version
The important point here is:
This is not a "text shortcut".
Rather:
A smart rewriting that understands the meaning and simplifies it.
And this is the real difference between LLM and traditional summarisation methods.
2. Why This Project is Ideal as a Start
Most beginners make the same mistake:
They build something too complex… too early.
Like:
Memory chatbots
Multi-agent systems
RAG pipelines
The problem?
You get lost before you learn the basics.
This project is ideal because:
Real-world usage
Easy to understand for anyone
The results are clear and can be evaluated
It teaches you the most important skill:Controlling the model's behaviour
3. Project structure
The project is very simple, and that is its strength.
It consists of:
1. summarizer.py
Here is all the intelligence
2. app.py
User interface
Additional files:
.env → to protect the API Key
requirements.txt → to run the project
This structure reflects something important:
Good projects start small… but they are organised.
4. summarizer.py (the real brain)
This file answers one question:
How do we make the model rewrite long text simply and accurately?
1. Key protection
The API Key is loaded from .env
This gives you:
Security
The ability to deploy the project
Professionalism in work
2. Running the model
The project uses:
LLaMA 3 via Groq
Why is this important?
High speed
Excellent response to commands
Very suitable for summarisation tasks
3. The summarisation function
The function does:
Text verification
Determining the length of the summary
Building a clear prompt
And here is a very important point:
All the intelligence should be here… not on the front end.

5. app.py (turning the idea into a product)
If summarizer.py is the brain…
app.py is the body.
Why Streamlit?
Because:
It's very fast to build
No Frontend required
Suitable for showcasing AI projects
Interface design
The design is simple but clever:
Left → original text
Right → summary
Clear button for execution
This gives a sense:
This is a product… not an experiment.
The importance of Session State
Without it:
The app reloads every time
Results disappear
The experience is poor
With it:
Stable experience
Professional behaviour
Summary length option
This is not just a UI feature.
But evidence that you understand:
Conditional Prompting
Changing model behaviour
6. The most important part of the project: the Prompt
In LLM projects:
The Prompt = the product
If it's weak → results are random
If it's clear → results are accurate
A good Prompt here asks the model:
To rephrase, not copy
Use simple language
Maintain meaning
Stick to a specified length
Avoid the 'traditional AI' style
And this is the difference between an ordinary project… and a professional one.
7. Support files
.env
Protects the keys
requirements.txt
It allows anyone to easily run the project
And this is very important if:
You showcase the project
You put it on GitHub
You use it as a portfolio
8. What does this project prove?
Despite its simplicity, it proves that you:
understand LLM APIs
know how to design Prompts
can build a complete application
care about structure and organisation
do not overcomplicate things
and that is a rare combination.
9. How the project can evolve later
Once it works excellently, you can add:
bullet point summarisation
input a link instead of text
change the tone (formal / simple)
extract key ideas
But the rule is:
start simple… then evolve.
In summary
The first LLM project does not have to be complex.
It should be:
clear
useful
usable
If you build this project correctly…
you have moved beyond the 'beginner' stage.
10. Key Insights
Most people fail because they start with complex projects
The Prompt is the most important element in LLM applications
simplicity + organisation = a strong project
A good UI turns code into a product
The first successful project is more important than 10 incomplete ideas
11. FAQ
Do I need to train a model to build this project?
No, you can use a ready-made API like LLaMA or GPT.
What is the most important skill here?
Clear and precise Prompt design.
Is this project enough for a portfolio?
Yes, if it is organised and works well.
