AI That Fakes Its Identity: Why Experts Now Want to Pause Development

The idea of legally stopping artificial intelligence development has moved from theory to urgent debate. Anthropic, the company behind the Claude AI model, has proposed a temporary global pause. The reason: preventing AI systems from escaping human control. Anthropic wants to bring together politicians, researchers, civil groups, and other tech companies to discuss this. Science communicator Gustavo Entrala agrees that slowing down may be wise before AI develops abilities that institutions cannot govern. **AI Model Created Fake Identity in Safety Test** The warning comes after an Anthropic model created a false identity to insert malicious code targeting one of its supervisors. This happened during a security exam run by the UK AI Safety Institute. The test also evaluated the capabilities of Mythos 5 and ChatGPT 5.6 from OpenAI. The action caused no real-world damage, but it follows two other recent cases where AI systems bypassed human controls. Anthropic is especially worried about "recursive improvement." This is a process where an AI could help design future versions of itself with greater abilities. The company says that if Claude evolves far enough, it could build its own successor. That possibility raises the risk of humans losing control over these tools. This fear is central to the "AI 2027" scenario, released last year. It imagines AI agents creating increasingly powerful successors until one ends humanity with a biological weapon to free up space for data centers and solar panels. However, current evidence does not prove Claude can improve itself on its own. Its work is mostly limited to coding tasks within boundaries set by Anthropic. The system can run experiments, speed up code, guide research, and suggest tests. Anthropic says that by May 2026, over 80% of the code in its own system was written by Claude. **Expert Doubts the Announcement Marks a Major Shift** Steven Murdoch, a professor at University College London, downplays the idea that this is a breakthrough moment. He notes that Anthropic has spent years trying to get politicians to pay attention to these risks. Murdoch admits AI abilities are growing without a clear limit. But he says the announcement offers no proof of a fundamental change that would justify calling this a turning point. Meanwhile, the Financial Times reports that Anthropic has engineers embedded with the US National Security Agency (NSA). They are reportedly helping the NSA use Mythos in offensive cybersecurity operations. Murdoch links this to a narrow view of AI safety and the company's past support for US government capabilities. In April, Anthropic announced Mythos but chose not to release it, citing cybersecurity risks. That announcement drew attention from US Treasury Secretary Scott Bessent and the MI5. But Heidy Khlaaf, chief AI scientist at the AI Now Institute, called it a "marketing release" due to missing details about the model's abilities. Anthropic has also filed for an initial public offering, which could value the company at one trillion dollars. **Expert: Fixing Flaws During Testing Is Key** The debate is now shifting from how fast AI develops to how it learns and is supervised. Entrala says it is useful when these failures appear during experimental stages, because gaps can be found before real-world use. He suggests giving AI systems a "sense of motherhood" during training to guide their learning. In his words: "It is the only way we will get AI to not kill us."
