Why

The models were built from all of us. Today’s AI assistants learned from decades of public writing, photos, code and conversation — most of it posted for other reasons by people who were never asked. Whatever you think about how that happened, the result is a capability that exists because of everybody.

Part of it is being given back. Open-weight models — ones you can download and run on your own computer — are that capability, handed out. They are smaller than the hosted giants, but for everyday use they are already good, and they get better every few months.

The part that isn’t given back is you. When you use a hosted assistant, cloud drive, or smart speaker, the service keeps what you put in. Your questions, files, photos, and the rhythms of your home become the raw material for the next product, on terms the provider can change whenever it likes.

So: keep the gift, close the loop. Run what you can at home. Where you still need a company’s servers — backups, mail delivery, a domain name — pick arrangements where the data is encrypted or portable, so the provider works for you and can be swapped out in an afternoon. That’s the whole idea. The guides do the rest.

One fair question: this site tells you to hand the hard parts to Claude, a hosted assistant. Yes. Use the big tool for the one-time move, then let your own local one take over the day-to-day. Using a ladder doesn’t mean living on it.
