The U.S. administration plans to lift export controls on Anthropic’s Fable 5 artificial intelligence model as soon as Tuesday evening, according to people familiar with the matter. The anticipated policy adjustment would permit Anthropic to restore public access to Fable 5 for all general users.
Anthropic halted public access to both its Mythos 5 and Fable 5 models earlier in June after receiving a White House directive intended to block foreign nationals from using those systems. The subsequent move to remove those export restrictions would reverse the narrower access regime and re-open Fable 5 beyond the limited user base imposed in June.
Last week the company said Washington had authorized the controlled release of Mythos to certain "trusted" U.S. organizations. Prior to that limited distribution, Anthropic had long delayed broadly releasing Fable and Mythos, citing concerns about the models' potential to be used in developing critical cybersecurity exploits.
Anthropic had initially consulted with several major U.S. organizations and banks ahead of making the models available to the public. The company made the models publicly accessible in early June before the White House order prompted the abrupt suspension of general access.

As presented by sources familiar with the issue, the planned regulatory change would effectively remove the export barrier that led Anthropic to curtail public use of Fable 5.
