About this guide

A calm, plain-language reference for using, understanding, and securing AI — written for whoever needs it, at whatever depth they need.

What this is

The AI Field Guide is a body of help and explanation, not a blog or a sales page. It serves the reader first: start at "what is a large language model?" and follow the links until you reach "run an open-source model locally and secure it", without ever hitting a dead end.

Who maintains it

It's maintained by Jamie Owen as a personal reference project. There's no company behind it and nothing to sell — the aim is simply to be the page you'd want to find when an AI question comes up at work.

How content is sourced and dated

Every page carries the date it was last updated. Anything that moves quickly — model versions, pricing, security guidance — is flagged fast-moving and, where relevant, names the source you should check for the current position. AI tools change monthly; treat dated specifics as a snapshot, and verify anything you're about to rely on.
