Tired of paying $20/month for ChatGPT? Yeah, me too. Here's how to run these AI models on your own machine - completely free and private. Learn to install and use local AI models like Llama, Qwen, and Phi3 with step-by-step instructions.
Look, I was skeptical at first. But after using local AI for months, I'm never going back to paid services for most tasks. Here's why:
- It's actually free - No subscription fees eating into your budget
- Your conversations stay private - Nothing gets sent to some company's servers
- Works when your internet doesn't - Perfect for flights or sketchy WiFi
- You can tinker with it - Want to modify how the AI behaves? Go for it.
LM Studio - This one's got a nice interface
- Download it and install (pretty straightforward)
- Browse models in the app - they've got tons
- Hit download, wait a bit, then start chatting
Ollama - My personal favorite
# Mac/Linux folks:
curl -fsSL https://ollama.com/install.sh | sh
# Windows people: Just download from the website
# Then try this:
ollama run llama3.2:3bHonestly, I'd recommend starting with LM Studio if you're new to this stuff. You can always try Ollama later.
This is important - you can't run huge models on a potato computer. But don't worry, there are good options for everyone:
| What you've got | What you can run | How good is it? |
|---|---|---|
| Basic laptop (8GB RAM) | 3B-7B models | Pretty decent for most stuff |
| Gaming rig (good GPU) | 13B models | Really good, honestly |
| Beast machine (16GB+ GPU) | 30B+ models | Scary good |
Not sure what you have?

- Linux: You probably already know, but
