Prompt Engineering vs Context Engineering
Key Takeaway Prompt engineering controls what you ask. Context engineering controls what the model sees. When a 6-token user message trigge…
Category 1: Foundational Patterns
Key Takeaway Prompt patterns are reusable templates for common AI tasks. Mastering 15 core patterns covers 90% of real-world use cases. Eac…
What Are Tokens?
Key Takeaway Every LLM interaction has a finite context window — a fixed budget of tokens for both input and output. More context is not au…
What Are Embeddings?
Key Takeaway Embeddings convert text into numerical vectors where meaningful relationships become mathematical distances. Words with simila…
The Sequence Modeling Problem
Key Takeaway Transformers process all tokens simultaneously using self-attention — a mechanism that lets every token compute how much it sh…
The Complete Pipeline
Key Takeaway LLMs generate text one token at a time through a repeating cycle: tokenize input → compute probabilities for every possible ne…
AI → Machine Learning → Deep Learning
Key Takeaway A Large Language Model (LLM) is a neural network trained on massive text data to predict the next token in a sequence. It does…
What Is Prompt Engineering?
Key Takeaway Prompt Engineering is the skill of communicating effectively with AI models. It is not about finding a "magic phrase" — it is …
The 20 AI Agent Projects
AI agents aren't just chatbots. They're systems that observe, plan, act, evaluate, and iterate. Building 20 progressively complex agents te…
Beginner Projects (1-5)
The best data science portfolio isn't 20 notebooks that all do the same thing. It's 20 projects that progressively build skills — from load…
The 8 Components of a Strong Portfolio
A GitHub portfolio isn't a collection of code — it's a signal to employers that you can build software, not just write scripts. Every file …
The 11-Stage AI Engineer Roadmap
AI engineering in 2026 is a distinct discipline requiring Python, machine learning, deep learning, LLMs, API design, RAG, agents, MCP, eval…
