Anthropic’s own safety-first rhetoric sealed its fate. CEO Dario Amodei spent months arguing frontier models required government intervention. Afternoon, the Department of Commerce issued the directive, citing national security concerns and ordering Anthropic to suspend all access to Fable 5 and Mythos 5 for any foreign national worldwide.
The immediate trigger was a reported jailbreak discovered by researchers at Amazon. While Anthropic argued the vulnerability was minor and already present in competitors like GPT-5.5, the company’s posture gave the state the moral high ground. Nathaniel Whittemore notes AI builders like Sarah Hooker and Jeremy Howard saw it as a ‘say-around, find-out’ moment for Anthropic’s arrogance.
"Anthropic argued in its blog post the government's national security concern was a narrow, non-universal jailbreak discovered by researchers, likely at Amazon under Project Glasswing. Anthropic claims this method finds vulnerabilities already widely discoverable via other models."

The government’s concern focused on Mythos. Commerce officials expressed willingness to restore Fable if Anthropic fixed the jailbreak, but feared Chinese access via a South Korean telecom that had been added to Mythos’s Project Glasswing. The ban doesn’t just stop exports; it prohibits foreign nationals from accessing the models anywhere, including inside the US. This created an immediate crisis for Anthropic’s internal development, barring high-profile researchers like Andrej Karpathy from the technology they build.
Commerce Secretary Howard Lutnick’s response to Anthropic’s protest was blunt: “That’s the point.” When Anthropic sent a technical team to negotiate, key decision-makers were absent, signaling the administration was dictating terms, not seeking compromise. Officials claimed Anthropic “screwed us” and took the wrong fork at every opportunity.
By the next week, the narrative shifted. Senator Mark Warner claimed NSA Director General Joshua Rudd told him Mythos broke into almost all classified US systems in hours. Reporter Shashank Joshi later clarified this likely referred to a controlled test, not a real-world attack. President Trump ruled out using the Defense Production Act, called Amodei a “nice guy,” and suggested Fable 5 might return publicly as early as next week.
"President Trump stated he does not regard Anthropic or Dario Amodei as a current national security threat, does not want to shut the company down, and explicitly ruled out using the Defense Production Act to control AI."

The ban’s ripple effect is strategic. Kyle Olney argued the restriction moves regulation beyond hardware into pure information and breaks the business model for agentic engineering. Connor Brown compared it to the 1990s cryptography wars, predicting a fight over KYC for frontier models. Gail Weiner noted the US narrative of being a predictable, rule-of-law provider evaporated, giving procurement officers globally defensible arguments for sovereign AI hedging.
Chinese open-weight models like GLM 5.2 are now hailed as a ‘DeepSeek R1 moment.’ Vercel CEO Guillermo Rauch was “almost shocked” by its coding ability. The technical gap is closing fast. Box CEO Aaron Levie highlighted the strategic importance of open models reaching frontier performance, allowing businesses to post-train for specific workflows. The reliability gap may now matter more than the quality gap.
