Anthropic and the US Government: Doing Business with the Apocalypse
The article analyzes the US government's order to block Anthropic's new AI chatbot models, Mythos and its secured version Fable 5, due to security concerns. The government cited risks of the models being used to find and exploit software vulnerabilities, potentially falling into the wrong hands. Anthropic initially released Fable 5 with protective redirects but complied with the shutdown order after Amazon CEO Andy Jassy warned that protections could be bypassed. However, Cybersecurity expert Dirk Engling from the Chaos Computer Club argues that such capabilities are not unique—existing open-source projects already do similar things—and that the true danger is overstated. He notes the tools can also help improve software security hygiene. The piece questions whether the government's drastic action is proportionate, framing it as a debate over AI risk, government control, and the real capabilities of current AI models.

Defense One - All ContentAmazon CEO Andy Jassy Helped Trigger U.S. Government Crackdown on AI Startup Anthropic, Report Says
According to reports from The Wall Street Journal, Reuters, TechCrunch, and The Information, Amazon CEO Andy Jassy told Treasury Secretary Scott Bessent and other officials that Amazon researchers used Anthropic's new Fable 5 model to obtain information potentially useful in cyberattacks. Shortly thereafter, the Trump administration imposed export controls, pulling both Fable 5 and the more powerful Mythos 5 offline worldwide. Anthropic disputes the characterization, calling the alleged jailbreak a minor vulnerability. The situation is unusual because Amazon has invested at least $8 billion in Anthropic and holds a stake worth over $74 billion on paper. Anthropic confidentially filed for an IPO earlier this month, reaching a private-market valuation of $965 billion, surpassing OpenAI. The controversy highlights new regulatory risks for AI companies and could affect the IPO's reception. Anthropic's CEO Dario Amodei had publicly warned about AI advancing too quickly days before the crackdown.
