Do you happen to know what kind of performance you can expect? Or perhaps a better way?
Are phones any good for that? (I agree with the rest, and I'm a big fan of termux, I just wouldn't have thought of a phone - especially an old phone - as a useful way to run AI)
Of course, that would require today's phones to age out of "being used as a phone" bracket, and robotics VLAs to become actually useful. But things like the Comma AI autopilot hardware use slightly obsolete smartphone chips internally - so it's not like it's impossible to run a useful AI on this kind of HW.
