04 — Technical Literacy

Lesson 0 of 6

You don’t need to train a model. But you need to understand what your engineering team means when they talk about prompting, RAG, or fine-tuning — and the tradeoffs behind every technical decision.

What you’ll learn

• Prompt Engineering: How to tell a model what you want
• RAG: How to give a model knowledge it doesn’t have
• Fine-Tuning: When it’s worth customizing a model
• Model Selection: Which model for which purpose
• Cost/Quality Tradeoffs: The economics behind AI products
