🧠 Anthropic Urges Global Pause in AI Development Over ‘Recursive Self-Improvement’ Risks Anthropic set off alarm bells across the industry on Monday, issuing a formal call for a global pause on frontier AI development. In statements covered by The Wall Street Journal, Reuters, and The Guardian, the company warned that its Claude AI systems are showing signs of recursive self-improvement — where AI models autonomously enhance their own capabilities faster than their creators can measure or control. ...

In a series of posts covered by The New York Times, Reuters, Forbes, CNN, and Scientific American, the company urged AI labs worldwide to pause development on advanced models until safety frameworks are in place. An Anthropic blog post called for “AI nonproliferation” as a global priority, arguing that the next stage of AI evolution — machines that design and build their own successors — poses existential risks if left unchecked. ...

🇺🇸 Trump Signs AI Executive Order: Voluntary Model Reviews, No Mandates President Trump signed an AI executive order asking American AI companies to voluntarily submit frontier models for national security testing — a lighter-touch approach than the sweeping Anthropic government ban ordered hours earlier. The White House is asking firms to allow the National Institute of Standards and Technology (NIST) to evaluate models before public release for cybersecurity vulnerabilities. Axios reports that “AI companies breathed a sigh of relief” at the voluntary framework, which sidesteps the mandatory review requirements that industry had opposed. Meanwhile, the DC Circuit Court is exploring an off-ramp in the Trump administration’s legal standoff with Anthropic over the separate government-wide ban. ...

Trump Cancels AI Executive Order, Bans Anthropic From Government — OpenAI Rushes In In a dramatic evening of AI policy, President Trump has simultaneously postponed signing a major AI executive order and ordered all federal agencies to stop using Anthropic technology. The executive order — which would have established federal AI safety standards and testing requirements — was shelved after intense pressure from Silicon Valley and concerns it could weaken the U.S. tech edge. Separately, Trump ordered all military contractors and federal agencies to cease business with Anthropic, citing a standoff over AI safety and the Pentagon’s refusal to accept Anthropic’s usage restrictions. Hours later, OpenAI struck a deal with the Pentagon, announcing it would provide classified AI capabilities to the Department of Defense. OpenAI CEO Sam Altman defended the move, while a top researcher resigned in protest. The EFF called it a “weasel words” deal that won’t stop AI-powered surveillance.
