If I Knew Absolutely Nothing About LLMs in : A Complete Roadmap

LLMs have completely disrupted the way we work. Anybody can 10x their potential with LLMs, but most don’t know how to leverage their power. Here’s a structured roadmap to build a strong foundation in LLMs:

The Basics

Before diving into frameworks, master the fundamentals:

1. Intro for Busy Users – Karpathy’s simplified guide.
2. Deep Dive into LLMs – Karpathy’s technical breakdown.
3. LLM Fundamentals (Stanford CS25 Lecture) – Core concepts explained.
4. The Original Transformer Paper – “Attention Is All You Need.”
5. How to Use LLMs – Practical guide by Karpathy.

✍️ Prompting 101

Prompting is a skill—master it to avoid frustration:

• Prompt Engineering by OpenAI – Best practices.
• OpenAI Cookbook – Ready-to-use examples.
• Prompting Guide – Comprehensive techniques.
• Mini Course on Prompting – Hands-on learning.

Next Steps: Advanced LLM Topics

Once comfortable, explore deeper:

• DeepLearning.AI’s Generative AI Learning Path – Fine-tuning, RAG, and agents.

You Should Know: Practical LLM Commands & Code

1. Running LLMs Locally (Linux/Windows)

• Install Ollama (Linux/macOS/WSL):

  curl -fsSL https://ollama.com/install.sh | sh 
  ollama pull llama3 
  ollama run llama3 
  

• Windows (PowerShell):

  winget install ollama 
  ollama pull mistral 
  ollama run mistral 
  

2. API Interaction with OpenAI (Python)

import openai 
response = openai.ChatCompletion.create( 
model="gpt-4", 
messages=[{"role": "user", "content": "Explain LLMs in simple terms."}] 
) 
print(response['choices'][0]['message']['content']) 

3. Fine-tuning with Hugging Face

pip install transformers datasets 
python -c "from transformers import pipeline; generator = pipeline('text-generation', model='gpt2'); print(generator('AI will change'))" 

4. Retrieval-Augmented Generation (RAG) Setup

git clone https://github.com/facebookresearch/faiss 
cd faiss && cmake -B build . && make -C build -j4 

What Undercode Say

LLMs are reshaping industries, and hands-on practice is key. Whether running models locally (ollama), integrating APIs (OpenAI), or fine-tuning (Hugging Face), the best way to learn is by doing. Experiment with RAG, agents, and custom prompts to unlock LLMs’ full potential.

Expected Output:

A structured learning path with practical code snippets for mastering LLMs in 2025.
