The U.S. government ordered Anthropic PBC to block foreign nationals from its AI models, prompting Anthropic to shut down that access.
Anthropic halted public use of Fable 5 and Mythos 5.
CEO Dario Amodei and executives met White House officials on Monday and Tuesday but saw no breakthrough.

Summary

White House Negotiates

White House moved from export controls to negotiating a technical standards framework with Anthropic to assess AI security flaws.
Commerce Secretary Howard Lutnick and National Cyber Director Sean Cairncross called Anthropic co-founder Tom Brown, after which Anthropic sent senior researchers to the Commerce Department.
The framework would benchmark AI jailbreak classification and safeguard bypasses, while Anthropic says the incident is a narrow, non-universal technique.

History

Historical Context

In the 1990s, Phil Zimmermann’s PGP and Netscape’s SSL exposed U.S. export limits that capped commercial encryption at 40-bit keys, prompting legal challenges and a 1996 Executive Order 13026 that moved encryption to the Commerce Control List under the Clinton administration. Those relaxations spurred e-commerce growth. Today White House talks with Anthropic echo that shift, as Commerce seeks safeguards before AI models leave United States.
