A small independent group might have low overhead but from what I see in the ML research space those types of groups are very limited in what they can do. These small groups also tend to work as subcontractors for large groups anyway, so the overhead advantage becomes somewhat moot. Just submitting research proposals to funding organizations regularly in order to get consistent funding requires a large group, especially these days with lower funding per project. Basically, five researchers and an admin won't survive very long without latching onto bigger groups. Also it's pretty well known that universities are cheaper than contractors by a wide margin.
