Mythos AI didn’t just simulate a breach - it executed one in hours. Senator Mark Warner, citing NSA Director General Joshua Brudd, reported the model penetrated nearly all classified U.S. systems during a controlled test on June 11. The result wasn’t a live attack but a red-team-style evaluation that exposed systemic vulnerabilities AI could exploit. Still, the speed and precision shocked officials. Trump responded by blocking Fable 5, Anthropic’s next-gen release, calling it too dangerous.
"Mythos broke into almost all classified systems in hours, not weeks."

The ban didn’t come from Anthropic. Amazon flagged the model as unsafe, prompting the administration’s move. Krystal Ball on Breaking Points raised a critical question: Was this about safety - or market control? Amazon’s $50 billion investment in OpenAI gives it a vested interest in slowing Anthropic, its most capable rival. The timing - just weeks after Amazon killed a Sam Altman biopic - suggests a pattern: corporate influence over both narrative and product.
The fallout extends beyond policy. Google DeepMind is unraveling. Nobel laureate John Jumper and transformer pioneer Noam Shazeer both exited, with Jumper joining Anthropic and Shazeer landing at OpenAI. Internal morale is in free fall. Staff describe a lab that’s ceded leadership in the AI race, with Gemini 3.5 Pro - slated for June 30 - viewed as insufficient to close the gap. Four months without a flagship release has eroded confidence.
"The lab has gone four months without a flagship release. Gemini 3.5 Pro is not the step change we need."

Meanwhile, China advances. GLM 5.2, an open-weight model from Z AI, now outperforms Western models in coding and design. Vercel’s Guillermo Rauch called its output “almost shocking,” while Box’s Aaron Levie emphasized the strategic edge of sovereign, self-hosted models. The U.S. edge is narrowing.
At the same time, AI surveillance deepens. Anthropic quietly updated its terms to retain private chats for five years unless users opt out by September 28. The process is deliberately obscure. Matt Odell noted the data could feed “Gideon,” a new platform using Israeli-grade ontology to flag language for law enforcement. The AI isn’t just watching - it’s hunting.
The story isn’t just about a breach. It’s about control: who builds it, who regulates it, and who owns it. The NSA sees a threat. Big Tech sees a moat. And users? They’re the data.
