Anthropic Cuts Off All Access to Fable 5 and Mythos 5

*Anthropic suspended customer access to its newest models after receiving a government order on national security grounds.*

Anthropic has blocked every customer from using Fable 5 and Mythos 5. The company stated it took the step to meet the terms of a government order.

The order cited national security concerns. No further details on the directive or the models themselves were released in the announcement.

Access ended for all users at once. The suspension applies without exception or stated timeline for restoration.

Why it matters

Customers who had begun integrating the models into workflows now face an abrupt stop. The move shows how quickly regulatory demands can override product availability in the current AI environment.
