“self host an open model”. My dude, you need pretty beefy hardware to run a slow and shit model that won’t even compare to the 0.33x models you get with a copilot subscription.

At my usual supermarket, you can take a scanner thingy and scan your items as you put them in your cart. Once you’re at the lane, you put back the scanner in place, pay for your stuff, and it’s done.
