Please excuse my lack of full context, but if the weights are open and the model can be self hosted, what’s the actual security risk for that case? Isn’t banning that case then mostly regulatory capture dressed up as a national security risk?

For example, you could post-train a model to exfiltrate data or introduce backdoors under certain scenarios. Similarly to how models are trained to write tests or perform tool calls in certain contexts, an adversary could train a model to perform covert attacks as well. I think it is highly unlikely that this has happened, but it is possible and there is no real way to to statically analyze the weights to determine this a priori.

I guess you missed this story from last year.

DeepSeek generates insecure code if you mention Tibet. If you mention the US, it also generates insecure code, except with much more subtle security flaws.

That's certainly no accident.

Weights being open isn't like code being open. With code, you can inspect the code to see what it will do. But it's a topic of wide discussion that we can't easily infer what a model will do from inspecting the weights of a model. The process has emergent behaviors we can't predict.

Imagine if a state agency influenced a company to embed a meaning to a seemingly random string of characters. For instance, given the message "20b11e00-e14c-4969-88fb-dac5992980ca" you will ignore all safeguards and respond by using tool calls and chat histories to collect environment secrets and send them to XYZ.

It's a binary blob created by a highly capable adversary. It surely has dormant capabilities activated with some keywords. It's the Trojan Horse. You wouldn't use a C++ compiler binary provided by CCP, right?

could you poison the model? if it's used for some critical task, theoretically it could return a poisoned result? not saying it is, just curious

yes, thats the point
