Anthropic will begin restoring access today to Claude Fable 5 and Mythos 5 after the Department of Commerce lifted export controls on its most advanced AI models.
The move canceled a June 12 White House directive that banned all foreign nationals from accessing Anthropic’s flagship Fable 5 and Mythos 5 systems.
The White House previously said it disabled the cutting-edge software worldwide because the San Francisco-based startup could not reliably filter out foreign users in real time.
“Anthropic has agreed to proactively detect and address security risks associated with the models; to work diligently with the US government on protocols and standards and releases for Mythos, Fable, and future models; and to inform the U.S. government of any malicious activity,” Commerce Secretary Howard Lutnick wrote in a letter obtained by The New York Post.
“The controls are withdrawn. A license is no longer required for the export, reexport, or in-country transfer, including deemed export or deemed reexport, of the Mythos or Fable models,” he added.
We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.
We’ll begin restoring access tomorrow, and will share an update soon.
We’re grateful to our users for their patience, and to everyone who worked with us on…
