Explore the difference between Prompt Engineering, Retrieval-augmented Generation (RAG), and Fine-tuning in this detailed overview.

01:14 Prompt Engineering + RAG
02:50 How Retrieval Augmented Generation Works - Step-by-step
06:23 What is fine-tuning?
08:25 Fine-tuning misconceptions debunked
09:53 Fine-tuning strategies
13:25 Putting it all together
13:44 Final review and comparison of techniques

Prompt engineering is a powerful tool to steer a large language model's behavior by providing instructions and examples directly in the prompt. RAG, a type of knowledge retrieval, grounds the model's responses to reality by pulling in dynamic and trusted external data sources. Fine tuning trains the model on your own examples to narrow and customize its outputs.

Each approach has its strengths. Prompt engineering is fast and intuitive, while RAG connects real-time data. Fine-tuning bakes in your style, tone, and formatting. The good news is they can all work together! Use prompt engineering to rapidly prototype, RAG to leverage your knowledge base, and fine-tuning to improve speed, cost, and quality.

In this video, Mark Hennings explains the unique value of each technique and shows how you can combine them for the best of all worlds. See examples of few-shot learning prompts and how they can be upgraded with fine-tuning datasets. Learn the specific fine-tuning strategies for optimizing cost, speed and quality.

There's something for everyone here. Whether you have experience with machine learning or just starting out with AI, this video will expand your understanding and give you ideas for improving your generative AI projects.

it's really fresh and accurate that u say "LLMs don't store facts, they just store probabilities". BTW, it's a very excellent video with wonderful backstage and straightforward script and presentation.

damn bro thanks, I'm new to fine-tuning, needed to migrate my rag model to the ragtag model, and your video was very clear and helped me a lot 😊

This is simple and super useful. Remember, putting it in simpler terms is not an easy job. Simplicity is the ultimate sophistication! 👏

These are some solid information you are providing in this video, I'm actually surprised that this video has such low amount of views. Just know, for those who are seeking information regarding the things you covered, these are very well presented and explained, and I really appreciate that.

Probably one of THE BEST large language model videos I’ve seen. 😮

I work in technical presales and delivery management. I probably watched 10 YouTube videos to try to better understand RAG vs. fine tuning (which I'm now calling TAG :)). This was by far the best explanation. I'm sending to all my coworkers!

I've been binge watching LLM-related videos and most have been regurgitation of docs or (probably) GPT/AI generated fluff pieces. This video clearly explained several concepts that I was trying to wrap my head around. Great job!

I work in this field - he did an exceptional job here. I would have liked to see FLARE in here an an extension of RAG.
