Open weights models are responsible for enabling reams of research on interpretability methods that do just that. And they have facilitated so much collaboration on architecture, inference optimizations, training and steering methods, and other topics that were completely out of reach with closed models like Anthropic's. It's really staggering to me.
“His warns that once powerful models are released openly, companies lose the ability to monitor misuse, revoke access, or update safety guardrails.”
Did fearmongers like Amodei say, "Oops, we were wrong! It wasn't that dangerous after all"? No. Of course they didn't.
1) the company has device-level control to the degree that they can not only restrict which API endpoints people can connect to but which accounts they use to do so (in which case this already isn't an issue); or
2) they don't, and all bets are off anyway, open weights or not.
