Weekend White House talks expected
Discussions between Anthropic and the White House over restoring access to Claude Fable 5 are expected to continue through the weekend, aiming for a lasting policy framework.
Partial reinstatement letter
Lutnick sends a letter to Anthropic's Tom Brown permitting access to Mythos 5 for select cyber defenders and infrastructure providers, while maintaining other restrictions.
In‑person technical meeting
Anthropic’s red‑team, safeguards, and security leads present cybersecurity protections to officials from Commerce and the Office of the National Cyber Director in Washington D.C.
Weekend crisis calls begin
Multiple hourslong calls take place between Anthropic co‑founder Tom Brown, Commerce Secretary Howard Lutnick, National Cyber Director Sean Cairncross, and Anthropic policy head Sarah Heck to discuss a path forward.
Initial directive issued
Commerce Secretary Lutnick issues a directive imposing requirements on Anthropic regarding its covered models, effectively restricting Mythos 5 and Claude Fable 5.
Export ban imposed
The Commerce Department blocks Anthropic from allowing non‑U.S. users to access its newest AI model due to potential security vulnerabilities, leading the company to remove the model from the market.
The Trump administration partially lifted its ban on Anthropic's Mythos 5, allowing 'a small group of cyber defenders and infrastructure providers' to use the powerful cybersecurity model. This limited reinstatement signals a cautious U.S. approach to AI-driven cyber defense, while consumer access remains restricted.
After an export ban halted Anthropic’s model for non‑U.S. users, its security leads presented red‑teaming results to the White House. The talks hinge on proving the model cannot be weaponized by foreign cyber threats.
