Many, many, many public policy positions; for a clear-cut example, they eventually supported SB 1047 [1] which would have banned open-sourcing any model trained with over 10^26 FLOPS (i.e. what Anthropic reportedly used to train Mythos). Their "Responsible Scaling Policy" [2] — a set of policy proposals that includes recommendations for government regulation — specifically calls out requiring "third-party controls" on model weights to prevent access; for developers to prevent "modification of models" such as fine-tuning (obviously impossible for open-source or open-weight models); prevent usage of model weights in "Automated R&D in key domains" which they specifically call out AI development as a key domain (again, obviously impossible for open-source); etc etc.
They want to ban open-source AI and are not shy about it.

Deeply concerning. How likely is this to become reality?
The nuance is not what they propose, but why, even according to them, they propose this. Honestly the proposals are appalling, but biosafety arguments are not immediately dismissible. Ultimate cyber threats we can handle by rewinding society 50 years back. We can’t undo a novel genetically engineered virus.
