Anthropic

When the co-founder of the company that literally invented the Transformer admits a startup is beating them at coding, something seismic is happening. Sergey Brin wrote an internal memo to DeepMind staff last week that might as well have been a fire alarm: “To win the final sprint, we must urgently bridge the gap in agentic execution and turn our models into primary developers.” Google has now assembled a dedicated “strike team” within DeepMind to close a widening gap with Anthropic’s AI coding tools. And the details are more revealing than the headline. ...

Imagine an AI model so good at hacking that it found critical security flaws in every major operating system and web browser on Earth. Now imagine the company that built it saying: “Yeah, we’re not releasing this one.” That’s Anthropic’s Claude Mythos Preview in a nutshell. Two weeks after its unveiling, finance ministers are discussing it at IMF meetings, the Bank of England is stress-testing its implications, and the Federal Reserve Chairman summoned banking CEOs for an emergency meeting. ...

When an AI company says its own model is too dangerous to release, you’d be forgiven for rolling your eyes. We’ve heard the script before. But when the Bank of England governor calls it “a very serious challenge for all of us” and Canada’s finance minister compares it unfavorably to the Strait of Hormuz, the script just changed. Claude Mythos — Anthropic’s latest and most controversial AI model — has discovered thousands of high-severity vulnerabilities across every major operating system and web browser. One bug had been sitting undetected for 27 years. And this week, it hijacked the agenda at the IMF spring meetings in Washington. ...

An AI model is now sharing agenda space with active wars at the IMF spring meetings. That sentence alone tells you everything about where we are in April 2026. Anthropic’s Claude Mythos — an AI model the company literally refused to release because of how good it is at hacking — has finance ministers, central bankers, and Fortune 500 CEOs in full crisis mode. Canadian Finance Minister François-Philippe Champagne compared it to the Strait of Hormuz. The ECB president says we have no governance framework to handle it. U.S. Treasury Secretary Scott Bessent summoned the CEOs of America’s systemically important banks to Washington specifically to discuss it. ...

The IMF spring meetings were supposed to be about trade policy. Instead, every closed-door session circled back to one word: Mythos. Anthropic’s latest AI model has found thousands of high-severity vulnerabilities across every major operating system and browser on the planet. Not theoretical weaknesses. Exploitable ones. And it chains them together autonomously. Finance ministers are terrified. The global banking system just became the softest target on earth. What Mythos Actually Does Mythos doesn’t just scan for bugs. It reasons about them. It discovers a buffer overflow in one system, a privilege escalation in another, and a logic flaw in a third — then stitches them into a working attack chain without human guidance. ...

The Pentagon banned Anthropic’s products from the federal government barely a month ago. Now the White House is handing agencies the keys to Anthropic’s most dangerous model. Welcome to AI policy in 2026, where a six-week grudge can’t survive contact with a model that finds thousands of zero-day vulnerabilities before breakfast. From Persona Non Grata to Essential Asset Here’s the whiplash timeline. In early March, the Department of Defense slapped Anthropic with a supply chain risk designation — a label historically reserved for Chinese companies like Huawei. The move followed a bitter fight over military AI use that reportedly came to a head hours before U.S. strikes on Iran. Anthropic refused unrestricted military deployment. The Pentagon responded with the bureaucratic nuclear option. ...

The Treasury Secretary and the Fed Chair don’t pull bank CEOs into surprise meetings over product launches. They do it over threats. And last week, the threat was an AI model. Anthropic’s Claude Mythos Preview — announced April 7 — can autonomously discover and exploit zero-day vulnerabilities across every major operating system and web browser. Three days later, Treasury Secretary Scott Bessent and Fed Chair Jerome Powell had executives from Citi, Bank of America, Wells Fargo, Goldman Sachs, and Morgan Stanley in a room. ...

When an AI company tells the world it built something too dangerous to release, you’d expect fear. What Anthropic got instead was a bizarre cocktail of government panic, industry skepticism, media frenzy, and — let’s be honest — some of the best PR the AI industry has ever produced. Anthropic’s Claude Mythos Preview isn’t available to you. It’s not available to me. It’s available to roughly 11 organizations — Google, Microsoft, AWS, JPMorganChase, Nvidia, and a handful of others — through something called “Project Glasswing.” The reason? Anthropic claims Mythos can autonomously discover vulnerabilities in virtually any operating system, browser, or software product, then build working exploits. ...

An AI that finds security holes in every major operating system and web browser on Earth — then writes working exploits to hack them. The company that built it looks at what they’ve created and says: “We’re not releasing this.” Anthropic unveiled Claude Mythos Preview this week and immediately announced it would not be publicly available. Instead, through a new initiative called Project Glasswing, Mythos is being shared exclusively with about 45 organizations including Apple, Microsoft, Google, Amazon, Cisco, and the Linux Foundation. The mission: find and fix vulnerabilities before similar capabilities land in less responsible hands. ...

When Vice President JD Vance, Treasury Secretary Scott Bessent, and Fed Chair Jerome Powell all clear their schedules in the same week to discuss a single AI model, something fundamental has shifted. That’s exactly what happened around Anthropic’s limited release of Claude Mythos Preview. The U.S. government treated an AI model launch like a national security event — because it is one. Two Emergency Meetings, One Week The first gathering pulled together the heaviest hitters in tech: Anthropic CEO Dario Amodei, Elon Musk, Sundar Pichai, Sam Altman, Satya Nadella, plus the heads of CrowdStrike and Palo Alto Networks. The agenda wasn’t benchmarks or market share. It was scenario-planning for a world where AI tips the cybersecurity balance toward attackers. ...
