You can run it on your laptop, I've tried it before (PS e.g. https://www.nomic.ai/gpt4all, it's fun to dig through your documents, but it wasn't as useful as I thought it would be in collecting ideas), what is truly hard is to train. But yeah, what is an AI PC? Is it like a gaming rig with lotsa RAM and GPU(s)?

It’s two things:

• a machine that has NN-optimized segments on the CPU, or a discrete NPU
• microslop’s idiotic marketing and branding around trying to get everyone to use Copilot

Computers now come with a NPU (Neural Process Unit) to do that job... So yeah.

To my knowledge, nobody is running LLMs on their personal hardware

They absolutely are.

Running an LLM locally is entirely possible with fairly decent modern hardware. You just won't be running the largest versions of the models. You're going to run ones intended for local use, almost certainly Quantized versions. Those usually are intended to cover 90% of use cases. Most people aren't really doing super complicated shit with these advanced models. They're asking it the same questions they typed into Google before, just using phrasing they used 20+ years ago with Ask Jeeves.

Lots of people are. Typically it means they have an NPU.

Not sure what the dell computers are doing but with something like Alpaca it’s pretty easy to run local LLMs

It is quite easy to run a distilled local model using a decent rig. I have one in that I use right from the terminal.
