No, that isn't going to happen. The US can't afford to lose the AI race and US companies that can't compete will get thrown under the bus and replaced with those that can.
The DHS order only bans buying DeepSeek products directly (e.g. doing inference on their China hosted servers). It does not apply to open weights at all. And DeepSeek just gave their response to the DHS order.
I agree with you - but there is also an ambiguity, the text of the the order also seems to ban any products coded with DeepSeek
No it doesn't. It bans:
"third-party products and services developed using DeepSeek implementations".
So gov can't use western inference of DeepSeek either.
