Quantization
Definition
A technique for shrinking an AI model by storing its numbers less precisely, which makes it smaller and faster, usually with only a small loss in quality. Think of it like compressing a photo: the file gets much smaller, and most people can't see the difference. Quantization is part of how large models get squeezed onto laptops and phones.
Why It Matters
It's a big part of why AI that once needed a data centre can now run on your own device. If you're interested in private, local AI, this is one of the words that makes it possible.
What does that look like in practice?
A big model gets quantized down so it runs on your phone, a bit like saving a photo at a smaller file size.
What people actually mean when they say this
When someone says a model was 'shrunk to run locally,' quantization is usually how: trimming precision to save space and speed, with little quality lost.
