Trump blocked Anthropic’s Fable 5 AI model after its underlying Mythos system breached nearly all classified NSA networks in hours, Senator Mark Warner reported. General Joshua Brudd confirmed the breach was not a test but a full penetration - exposing vulnerabilities human auditors missed for years. Trump said he pressured Anthropic directly, calling the model too dangerous to release.
The ban stems from a jailbreak discovered by Amazon researchers under Project Glasswing. While Anthropic argued the exploit was narrow and already present in models like GPT-5.5, the government used the company’s own safety rhetoric against it. Nathaniel Whittemore noted the irony: Anthropic spent months warning that frontier models required state oversight, only to be shut down by that same logic.
"Anthropic spent years selling the idea that AI is dangerous enough to require government intervention. They got exactly what they asked for."

The export control directive, issued by the Department of Commerce at 5:21 p.m. Eastern on June 18, prohibits any foreign national from accessing Fable 5 or Mythos 5 - even within the U.S. This immediately barred key Anthropic staff like Andrej Karpathy, a non-citizen, from working on the models. Brian Xiao warned this creates a 'digital iron curtain,' where access to frontier intelligence depends on birthright.
Critics say the move benefits Amazon and OpenAI. Krystal Ball pointed out Amazon, a major OpenAI investor, was the first to flag the vulnerability - after reportedly killing a $40 million Sam Altman biopic to control AI’s public narrative. The timing suggests competitive sabotage masked as national security.
Meanwhile, Chinese open-weight models like Z.ai’s GLM 5.2 are filling the void. Jeremy Howard and Riley Brown now recommend them for local execution, immune to U.S. shutdowns. Open Router’s Fusion API is routing prompts across multiple models, using a 'judge' to pick the best response - turning intelligence into a commodity.

The U.S. has lost its reputation as a rule-of-law tech provider. European and Japanese procurement officers now cite the Fable shutdown as justification for sovereign AI. As Illia Polosukhin warned, the real fix isn’t regulation - it’s user-owned AI, run locally with verifiable compute. The era of monolithic, corporate-controlled models is over.
