Who decide the if a model is safe to use?

The strongest competitors or a government law? I prefer the second.

Suppose Chinese model are super-risky: is it better to have them in the open, so everyone can review the problems or have a closed-model?

Security is better at open Linux is open source because development is better.

I understand Anthropic for sure, but trying to limit open weight model seems the opposite direction IF security+safety is the major concert.

The Genie is ALREADY outside the bottle, and there are already plenty of companies offering inference services
