Foundations
The core concepts behind Local AI tool. Here you'll understand exactly why a model says "70B," what quantization does, and what determines whether it fits on your GPU.
What is Local AI?
AI used to live in the cloud. Now it can live on your machine — privately, offline, and fast.
What is an LLM?
ChatGPT is one. So is Llama. So is Claude. Here's how they actually work.
Diffusion Models
How does a computer turn words into a picture? It starts with pure noise and works backwards.
Parameters
Why does "70B" matter? Parameters are the knobs the model learned during training.
Quantization
Same model, smaller file, almost as smart. How precision trades off against VRAM.
Tokens & Context Windows
AI reads in chunks, not letters. Your context window decides how much it can "see" at once.
VRAM & Model Size
The single biggest factor in "can I run this?" — with an interactive calculator.
