The impression I get from what I read is that AI safety people want to have large cutting edge foundational models they control, can do testing and research on.

The impression I get from what I read is that AI safety people want to have large cutting edge foundational models they control, can do testing and research on. They have no interest in open sourcing those cutting edge models. Whether this makes sense in the long run I don't know, but it is what I meant by AI safety types. Of course money makers want to keep it closed source to extract rent. In some ways that is an area of agreement between the capitalists and the safety people.
