Module 1: Introduction to Fine-Tuning
Understanding When and Why to Fine-Tune LLMs
This module introduces the fundamental concepts of fine-tuning large language models, helping you make informed decisions about when fine-tuning is the right approach for your use case.
What You'll Learn
In this module, you will:
- Understand what fine-tuning is and how it relates to transfer learning
- Learn when to fine-tune versus using RAG or prompt engineering
- Explore the fine-tuning landscape including methods, tools, and compute requirements
- Make informed decisions about the right approach for your specific needs

Key Concepts Preview
Fine-Tuning
Continuing the training of a pre-trained model on a specific dataset to adapt it to a particular task or domain.
Transfer Learning
Using knowledge gained from pre-training on large datasets to improve performance on downstream tasks.
Pre-trained Model
A model that has already been trained on a large corpus (like the internet) and has learned general language understanding.
Adapter
A small, trainable module added to a frozen pre-trained model that enables efficient fine-tuning.
Why This Matters
Fine-tuning is one of the most powerful techniques for customizing LLMs, but it's not always the right choice. Understanding when to fine-tune versus using other approaches like RAG or prompt engineering is crucial for:
- Cost efficiency: Avoiding unnecessary compute expenses
- Time-to-market: Choosing the fastest path to a working solution
- Quality: Achieving the best possible results for your use case
- Maintainability: Building systems that are easy to update and improve
Prerequisites
Before starting this module, you should have:
- Basic understanding of what large language models are
