Amazon's AI Security Research Led to the White House Blocking Foreign Nationals From Anthropic's Models

Amazon's cybersecurity team spent months probing Anthropic's Fable 5 model. They fed it prompts until it started spitting out details useful for cyberattacks — things like vulnerability data that could be used against U.S. companies. They put it in a paper.

Andy Jassy took those findings to the White House. Within days, the government issued an export control directive that told Anthropic to cut off foreign nationals from using Fable 5 and Mythos 5. Anthropic complied. Amazon hasn't said anything since.

The directive didn't just hit researchers and students — it affects immigrants, workers, and small business owners who rely on these models for their work. The White House is now deciding which of us can use AI and which of us can't.

Why this matters for us: when policy makers start drawing lines around who gets access to the tools that power the economy, our comunidad ends up paying the price without always knowing who drew the line.
