> Lots of organizations are continuing to refuse to use chinese models due to security and IP concerns

This is such a common omission: the Chinese models are open, you can host them yourself on your premises. So privacy and independence.

it's well documented that models can be adversarially trained with essentially backdoors in response to special inputs

while I am skeptical that this is happening atm, there are probably many industries where the risk does not seem worthwhile

I suppose this is like when Anthropic was using “prompt modification, steering vectors, or parameter-efficient fine-tuning” to poison the work of people working in the LLM field, including academic researchers.

No, that was totally different. They were just doing that for your safety.

When the model is open weights you can even pass every token (including the chain of thought) though a fourth-party lightweight model like gpt-oss-safeguard to check that it has not become adversarial.

So it's better to trust cloud solution where not only they can do the same, but also actively use your data?

Because in 2026 we still believe USA is more trustworthy than China?

I feel like that's a threat that isn't super difficult to block. Unplug it from the internet, require it to go through an API intermediary to access web pages.

Maybe I just don't have any imagination.

It could generate code that's plausible but has intentional flaws, kind of like the defunct underhanded C contest [0], except through a LLM.

It could, but exposing that would doom the company entirely, and AI doesn't generate code with near the quality needed to get a model to mass adoption, insert malicious underhanded code, ensure that consistently looks innocuous enough to never be noticed, and- most importantly- actually exfiltrate data without being noticed. Once it is noticed, it's game over across the board.

You don't even need that, all models are susceptible to prompt injection. You already need to take extreme security precautions and assume all models can essentially behave like attacker-controlled rootkits.

That's right, but this strategy only works when there are no opponents of the same level to review the generated code.

For several export controlled industries in the United States, even self-hosting a Chinese model is a non-starter.

Good luck hosting 2.8T params yourself. A box capable of this at a useful performance level is at least $100k.

More like $500k, but that's not an unreasonable price for a medium sized enterprise to pay.

I have an RF engineering background, a nice mmWave vector network analyzer can easily land in that ballpark.

If the business value is there, companies will pay for it.

Not to mention the bill you would be paying anthropic could be way higher at that scale

How much would it cost to run a 2.8T model with long context for 1000 developers, plus 30,000 non-dev employees with short session memory?
