Is it really feasible to run it 100% locally? I know there’s plenty of people with very powerful rigs indeed, but still. Or are 99% of these people really saying “it would, in theory, be possible to run that locally, therefore your concerns are invalid”?

There’s usually a lot of caveats they don’t mention on this. Like saying it** is feasible to run it** locally! (** it depends on your rig, memory and storage constraints, model licensing constraints blah-di-dah, blah-di-dee)

Yes, there are super small and simple models so this is technically true.
