Anthropic said Friday it will remove access to two AI models, Fable 5 and Mythos 5, to comply with a Trump administration directive restricting foreign nationals from using its latest systems due to security concerns.

Anthropic PBC Chief Executive Officer Dario Amodei said the government should have the power to block artificial intelligence developers from deploying new AI models if they present certain risks.

Anthropic PBC was forced to abruptly pull the plug on foreign access to two of its most powerful artificial intelligence models, Fable 5 and Mythos 5, just days after it launched them. The sudden decision to do so came shortly after the U.S. Commerce Department issued a sweeping export control order citing urgent security concerns over the models.

Anthropic says Mythos won't help users build competing AI models. Critics said the move quietly degrades responses and limits competition.

Guardrails make the powerful model less useful for AI researchers, though the company said it would grant safeguard-free access to the science community.

The order asks AI companies to share previews of powerful new models with the government before they are released to the public.
