Open Source vs Closed AI Models — Why It's a Big Deal
Some AIs are public code anyone can run. Others are locked black boxes. The difference shapes the whole industry.
What to actually do
- Open models can be run on your own laptop (small ones) or your own server
- Closed models are easier to use but you depend on the company
- Most cutting-edge research is still happening in closed labs — but open models catch up fast
Key terms in this lesson
The big idea: Open and closed AI both matter. The choice changes who controls the technology and who can build with it.

Section 3
The big idea
Open-source AI in 2026 is good enough for most schoolwork — and runs offline so nothing leaves your machine. Ollama makes it free.
Some examples
- Install Ollama: one command, then 'ollama run llama4:8b'
- Llama 4 8B works on any 16GB Mac
- Qwen 3 is best for coding, Mistral for writing
- Zero internet, zero training data sent — fully private
Try it!
If you have a 16GB+ machine, install Ollama tonight. Pull llama4:8b. Have a real conversation offline. You'll see why this matters.

Section 5
The big idea
Meta's Llama, Mistral, and Qwen are open-source models — free to download, run on your own computer, and modify. Apps like Ollama (free) let you run a real AI on a 2-year-old MacBook with no internet. They're not as smart as GPT-4o, but they're private, free, and yours. That's a real choice the closed tools can't offer.
Some examples
- Ollama.com: free local AI in 5 minutes.
- Llama 3.1 8B runs on most modern laptops.
- No data leaves your machine — full privacy.
- LM Studio is another free option with a nice UI.
Try it!
Visit ollama.com. The install is 2 minutes. Run a small model and ask it a question. You just ran AI offline.
