Agree. And re small models - very agree. In fact I made a ablated version of Qwen 3.5-2B for use with my pi, before thinking a bit harder and realising I can probably code something bespoke that doesn't need a stochastic parrot as a squwake box at all.

Still, as a SLM, it's perfectly cromulent and does well with tool calling etc which is what I wanted it for.
Agree. I know the Pi's are out of favour these days...but they are a cool little machine. I got mine running DietPi and a bunch o crap (the usuals - JF, arr stack, pi hole, syncthing, yadda yadda) and running headless the footprint (power and memory wise) is tiny.
I joked about the 4xAA batteries thing but iirc, there is actually a Pi-HAT that creates a micro UPS that'll run the pi for maybe three to five hours just on double A batteries.
