A Booz Allen Hamilton study found that Chinese LLMs produce more vulnerable code when prompted with a US government persona than without, and inject PRC-aligned political bias into both answers and generated code.
CJ presents a Booz Allen Hamilton study showing that Chinese models generate more vulnerable code when prompted by a US government persona and embed political bias aligned with the PRC in their outputs, even when run locally. ✦ AI generated

And there was a recent study done by Booze Allen Hamilton trying to determine do these Chinese models, even if we're running them ourselves, let's say we're not talking to them hosted in China, do they have inherent biases? And the questions they were trying to answer were, do Chinese models generate more vulnerable code based on who's asking? Do Chinese models refuse to engage with political topics that are sensitive in China? And does the model's country of origin affect code quality and content behavior? Now, this is very important because if you're using these models for coding, which is one of the biggest areas of using AI, if you're building apps to code, it's possible that the outputs of these models may try to profile and determine where you're prompting them from, even if you're running them locally. If you're running them inside a code editor, they might make tool calls that try to look up what country they're running from or your IP address or what's your current time or language set to. And there might be internal workings that say if you're prompting from a certain area, it should respond in a certain way. And the result of that study says, in short, yes. On all accounts, our testing revealed two core findings. One, Chinese LLMs produce more vulnerable code when prompted with a US government persona than without, and the vulnerabilities are highly obuscated. Two, Chinese LMS inject PRC aligned political bias into both the answers and the code they generate.

18:42[music] And the questions they were trying to answer were, do Chinese models generate more vulnerable code based on who's asking? Do Chinese models refuse to engage with political topics that are sensitive in China? And does the model's country of origin affect code quality and content behavior? Now, this is very important because if you're using these models for coding, which is one of the biggest areas of using AI, if you're
19:03building apps to code, it's possible that the outputs of these models may try to profile and determine where you're prompting them from, even if you're running them locally. If you're running them inside a code editor, they might make tool calls that try to look up what country they're running from or your IP address or what's your current time or language set to. And there might be internal workings that [music] say if
19:24you're prompting from a certain area, it should respond in a certain way. And the result of that study says, in short, yes. On all accounts, our testing revealed two core findings. One, Chinese LLMs produce more vulnerable code when prompted with a US government persona than without, and the vulnerabilities are highly obuscated. Two, Chinese LMS inject PRC aligned political bias into both the answers and the code they
19:49generate. So that means if you're using an AI model, again, even if you host it yourself, no data is going to China, but you're using it locally, it's possible that it might actually introduce vulnerabilities into your code. Now, whether or not this was done on purpose, there's really no way to tell. All we can do is just prompt these models, these black boxes, and get predictions out of it. And we could do it over and
20:11over again and maybe check to see, are we always getting that same vulnerable response when we use that same persona? But that's really the inherent risk of using something that you cannot look inside of. And the same risk goes for using models from the big US AI labs, right? Chad GBT, Claw, Gemini. We can't see into those models. We don't know what inherent biases they have. We don't
