  • Claude Code Defaults to Auto Mode. The Classifier Catches More Than Humans.

    Claude Code Defaults to Auto Mode. The Classifier Catches More Than Humans. Claude Code will ship with Auto Mode enabled by default starting August 14 for Pro, Max, and Team subscribers, shifting the developer role further from active coding toward reviewing AI-generated output. Only Enterprise customers will need to opt in. Auto Mode lets the agent execute steps without waiting for manual approval at each one. A classifier intercepts actions the model judges dangerous or irreversible and paus

  • Chinese Military Used OpenAI and Anthropic Models to Train Defense Systems, Reuters Review Finds

    Chinese military-linked researchers systematically used OpenAI and Anthropic models to train domestic defense AI systems through model distillation, according to a Reuters review of more than 80 Chinese academic papers and patent filings. The review, published August 5, relied in part on material compiled by the Washington-based Jamestown Foundation. Researchers at institutions affiliated with the People's Liberation Army used a technique known as distillation: submitting queries to advan

  • The Fable 5 shutdown exposed a gap in US AI kill-switch authority

    In June 2026, the Commerce Department ordered Anthropic to cut off global access to its Claude Fable 5 and Mythos 5 models just three days after launch. The order required Anthropic to block all foreign nationals from using the models. Because Anthropic could not verify user nationality in real time across dozens of cloud platforms, it shut the models down for everyone, everywhere, for over two weeks. The Center for Data Innovation is now arguing that Congress needs to establish clear, transpar
