The required specs seemed a bit high to me, and I was just looking for alternatives.

I found Project Nomad (https://projectnomad.us) which looks more polished. Any other suggestions?

I just use llama cpp , it's light weight, I think you create your own integrations, with a larger model so llama cpp can interract with scripts that would browse the web, control your computer etc... propably will have to download some pip packages
