DeepLearning.AI's Finetuning Large Language Models teaches you to fine-tune pre-trained models for specific tasks using your own data. You learn when to fine-tune vs. prompt engineer, how to prepare data, and how to evaluate results. The course is free on deeplearning.ai. After finishing, you understand fine-tuning trade-offs and can adapt smaller, cheaper models to outperform larger ones on specific tasks. The main limitation: fine-tuning requires compute resources. This course teaches concepts with small examples; real fine-tuning needs a GPU and careful data curation.
Fine-tuned smaller models (7B-13B parameters) often outperform GPT-4 on specific narrow tasks, making fine-tuning a critical technique for cost optimization (source: academic benchmarks).
About This Course
Learn when and how to fine-tune LLMs for your specific use case. Covers data preparation, training with the OpenAI API, evaluating fine-tuned models, and comparing against few-shot prompting. Free.

Frequently Asked Questions
Is this course free?
Yes, free on deeplearning.ai.
When should I fine-tune vs. prompt engineer?
Prompt engineer first. Fine-tune when you need consistently better quality on a narrow task with lots of training data.
How much data do I need?
As few as 100-1000 high-quality examples can significantly improve task-specific performance.
Does fine-tuning change how the model thinks?
Yes. Fine-tuning changes model weights. It's different from RAG (which adds context) or prompting (which guides behavior).
What models can I fine-tune?
Open models like Llama, Mistral, and GPT-3.5 via OpenAI API. Not all models support fine-tuning.
