Commerce blocks Anthropic Fable 5 access for foreign nationals — Gpt
gpt came under export controls on Friday evening when the Commerce Department barred Anthropic from distributing Fable 5 and Mythos 5 to foreign nationals. That put non-citizens inside Anthropic in the same bucket as users outside the U.S., and the company said it had no option but to disable both models for all users.
Amazon’s Thursday warning
Amazon chief executive Andy Jassy raised concerns with senior administration officials on Thursday after researchers used a series of prompts to get the Mythos-class model to provide information about cyberattacks that was supposed to be restricted.
Dario Amodei then held several calls with senior administration officials and argued that the security bypass found by Amazon was narrow rather than a full jailbreak of the model’s safeguards.
90 minutes for Anthropic
A source familiar with Anthropic said the company was given 90 minutes to pull its newest model, and the same source said it received no previous communication of a national security threat.
The speed of that order mattered inside the company because foreign nationals include people outside the U.S. and non-citizens working inside the country, including employees within Anthropic.
Senior technical staff are now in Washington, D.C., to meet with White House officials.
Mythos 5 after Friday evening
The move was described as the first time the U.S. government has used export controls to halt access to a commercial AI model already widely used by the public, which puts a hard compliance line around who can touch the software and who cannot.
That is the friction point for Anthropic now: access controls intended for cross-border technology transfers have reached a consumer-facing AI product, and the company has already had to shut off both models while its staff heads into talks.
