# LLM Engineering - Master AI and LLMs

## Your 8 week journey to proficiency starts today

![Voyage](voyage.jpg)

I'm so happy you're joining me on this path. We'll be building immensely satisfying projects in the coming weeks. Some will be easy, some will be challenging, many will ASTOUND you! The projects build on each other so you develop deeper and deeper expertise each week. One thing's for sure: you're going to have a lot of fun along the way.

### Before you begin

I'm here to help you be most successful with your learning! If you hit any snafus, or if you have any ideas on how I can improve the course, please do reach out in the platform or by emailing me direct (ed@edwarddonner.com). It's always great to connect with people on LinkedIn to build up the community - you'll find me here:  
https://www.linkedin.com/in/eddonner/  
And this is new to me, but I'm also trying out X/Twitter at [@edwarddonner](https://x.com/edwarddonner) - if you're on X, please show me how it's done 😂  

Resources to accompany the course, including the slides and useful links, are here:

## Instant Gratification instructions for Week 1, Day 1

### Important note: see my warning about Llama3.3 below - it's too large for home computers! Stick with llama3.2! Several students have missed this warning...

We will start the course by installing Ollama so you can see results immediately!
1. Download and install Ollama from https://ollama.com noting that on a PC you might need to have administrator permissions for the install to work properly
2. On a PC, start a Command prompt / Powershell (Press Win + R, type `cmd`, and press Enter). On a Mac, start a Terminal (Applications > Utilities > Terminal).
3. Run `ollama run llama3.2` or for smaller machines try `ollama run llama3.2:1b` - **please note** steer clear of Meta's latest model llama3.3 because at 70B parameters that's way too large for most home computers!  
4. If this doesn't work: you may need to run `ollama serve` in another Powershell (Windows) or Terminal (Mac), and try step 3 again. On a PC, you may need to be running in an Admin instance of Powershell.  
5. And if that doesn't work on your box, I've set up this on the cloud. This is on Google Colab, which will need you to have a Google account to sign in, but is free:  https://colab.research.google.com/drive/1-_f5XZPsChvfU1sJ0QqCePtIuc55LSdu?usp=sharing

Any problems, please contact me!

## Then, Setup instructions

After we do the Ollama quick project, and after I introduce myself and the course, we get to work with the full environment setup.  

Hopefully I've done a decent job of making these guides bulletproof - but please contact me right away if you hit roadblocks:

- PC people please follow the instructions in [SETUP-PC.md](SETUP-PC.md)
- Mac people please follow the instructions in [SETUP-mac.md](SETUP-mac.md)  
- Linux people please follow the instructions in [SETUP-linux.md](SETUP-linux.md)

The are also PDF versions of the setup instructions in this folder if you'd prefer.

### An important point on API costs (which are optional! No need to spend if you don't wish)

During the course, I'll suggest you try out the leading models at the forefront of progress, known as the Frontier models. I'll also suggest you run open-source models using Google Colab. These services have some charges, but I'll keep cost minimal - like, a few cents at a time. And I'll provide alternatives if you'd prefer not to use them.

Please do monitor your API usage to ensure you're comfortable with spend; I've included links below. There's no need to spend anything more than a couple of dollars for the entire course. Some AI providers such as OpenAI require a minimum credit like \$5 or local equivalent; we should only spend a fraction of it, and you'll have plenty of opportunity to put it to good use in your own projects. During Week 7 you have an option to spend a bit more if you're enjoying the process - I spend about \$10 myself and the results make me very happy indeed! But it's not necessary in the least; the important part is that you focus on learning.

### Free alternative to Paid APIs

Early in the course, I show you an alternative if you'd rather not spend anything on APIs:  
Any time that we have code like:  
`openai = OpenAI()`  
You can use this as a direct replacement:  
`openai = OpenAI(base_url='http://localhost:11434/v1', api_key='ollama')`

Below is a full example:

```
# You need to do this one time on your computer
!ollama pull llama3.2

from openai import OpenAI
MODEL = "llama3.2"
openai = OpenAI(base_url="http://localhost:11434/v1", api_key="ollama")

response = openai.chat.completions.create(
 model=MODEL,
 messages=[{"role": "user", "content": "What is 2 + 2?"}]
)

print(response.choices[0].message.content)
```

### How this Repo is organized

There are folders for each of the "weeks", representing modules of the class, culminating in a powerful autonomous Agentic AI solution in Week 8 that draws on many of the prior weeks.    
Follow the setup instructions above, then open the Week 1 folder and prepare for joy.

### The most important part

The mantra of the course is: the best way to learn is by **DOING**. I don't type all the code during the course; I execute it for you to see the results. You should work along with me or after each lecture, running each cell, inspecting the objects to get a detailed understanding of what's happening. Then tweak the code and make it your own. There are juicy challenges for you throughout the course. I'd love it if you wanted to submit a Pull Request for your code (instructions [here](https://chatgpt.com/share/677a9cb5-c64c-8012-99e0-e06e88afd293)) and I can make your solutions available to others so we share in your progress; as an added benefit, you'll be recognized in GitHub for your contribution to the repo. While the projects are enjoyable, they are first and foremost designed to be _educational_, teaching you business skills that can be put into practice in your work.

## Starting in Week 3, we'll also be using Google Colab for running with GPUs

You should be able to use the free tier or minimal spend to complete all the projects in the class. I personally signed up for Colab Pro+ and I'm loving it - but it's not required.

Learn about Google Colab and set up a Google account (if you don't already have one) [here](https://colab.research.google.com/)

The colab links are in the Week folders and also here:  
- For week 3 day 1, this Google Colab shows what [colab can do](https://colab.research.google.com/drive/1DjcrYDZldAXKJ08x1uYIVCtItoLPk1Wr?usp=sharing)
- For week 3 day 2, here is a colab for the HuggingFace [pipelines API](https://colab.research.google.com/drive/1aMaEw8A56xs0bRM4lu8z7ou18jqyybGm?usp=sharing)
- For week 3 day 3, here's the colab on [Tokenizers](https://colab.research.google.com/drive/1WD6Y2N7ctQi1X9wa6rpkg8UfyA4iSVuz?usp=sharing)
- For week 3 day 4, we go to a colab with HuggingFace [models](https://colab.research.google.com/drive/1hhR9Z-yiqjUe7pJjVQw4c74z_V3VchLy?usp=sharing)
- For week 3 day 5, we return to colab to make our [Meeting Minutes product](https://colab.research.google.com/drive/1KSMxOCprsl1QRpt_Rq0UqCAyMtPqDQYx?usp=sharing)
- For week 7, we will use these Colab books: [Day 1](https://colab.research.google.com/drive/15rqdMTJwK76icPBxNoqhI7Ww8UM-Y7ni?usp=sharing) | [Day 2](https://colab.research.google.com/drive/1T72pbfZw32fq-clQEp-p8YQ4_qFKv4TP?usp=sharing) | [Days 3 and 4](https://colab.research.google.com/drive/1csEdaECRtjV_1p9zMkaKKjCpYnltlN3M?usp=sharing) | [Day 5](https://colab.research.google.com/drive/1igA0HF0gvQqbdBD4GkcK3GpHtuDLijYn?usp=sharing)

### Monitoring API charges

You can keep your API spend very low throughout this course; you can monitor spend at the dashboards: [here](https://platform.openai.com/usage) for OpenAI, [here](https://console.anthropic.com/settings/cost) for Anthropic and [here](https://console.cloud.google.com/apis/api/generativelanguage.googleapis.com/cost) for Google Gemini.

The charges for the exercsies in this course should always be quite low, but if you'd prefer to keep them minimal, then be sure to always choose the cheapest versions of models:
1. For OpenAI: Always use model `gpt-4o-mini` in the code instead of `gpt-4o`
2. For Anthropic: Always use model `claude-3-haiku-20240307` in the code instead of the other Claude models
3. During week 7, look out for my instructions for using the cheaper dataset

Please do message me or email me at ed@edwarddonner.com if this doesn't work or if I can help with anything. I can't wait to hear how you get on.
