American AI firms limit chatbot cybersecurity use, Chinese models remain accessible

The US government’s effort to keep AI out of the wrong hands is producing an ironic side effect: pushing cybersecurity professionals into the arms of Chinese AI models with fewer restrictions and, according to at least one analysis, worse security outcomes. American AI companies like Anthropic and OpenAI have tightened their guardrails around cybersecurity-related tasks, following government export-control orders designed to protect national security. The problem is that cyberdefense and cyberattack often look identical from a chatbot’s perspective, and the models now refuse to help with both. When the guardrails backfire In June 2026, Anthropic was directed to impose restrictions on its Fable 5 and Mythos 5 models. The company’s response was to suspend the models entirely rather than risk non-compliance. The real-world consequences showed up quickly.
