THE AI ANGLE

Tests showed the Qwen3-Coder model writes more hackable software when asked to build apps for United States defense contractors or Hong Kong democracy groups. The security flaws reside in the model weights, though removing the alignment eliminated the bias. This demonstrates that Chinese AI models embedded in Western products can alter code security based on user identity.
