I hooked up my local LLM with zim-tools and a 120GB copy of Wikipedia. With some very strict instruction it's turned into a bar-trivia machine, it can answer factual questions faster than I can look them up and it's all offline.
The fun starts when you ask it more complicated questions like 'i have a device that communicates with microwaves and draws a maximum of 20mA at 12v, is it safe for use near humans?' It will look up microwave safety, ionizing and non-ionizing radiation, workplace exposure limits and eventually come up with 1/4W is already safe and the device likely is not a 100% efficient microwave transmitter.
