Baker's choice. Dense with flavour, light on filler.
Summary
The U.S. government has invoked emergency export control powers to force Anthropic to immediately suspend global access to its advanced AI models, Fable 5 and Mythos 5, citing national security concerns. The action was triggered by a claimed "jailbreak" that reportedly exposed minor vulnerabilities. This represents a major escalation in treating frontier AI systems as sensitive defense assets subject to real-time kill switches, affecting even the company's own employees and foreign nationals worldwide.
