Anthropic Battles White House Order to Block Foreign Access to Fable 5 and Mythos 5

Original: All the news about Anthropic’s new AI fight with the White House

A June 12th US government order demands Anthropic cut off foreign access to its just-launched Fable 5 and Mythos 5 models.

Anthropic is simultaneously fighting two government disputes: a pre-existing standoff with the Pentagon and a new White House order issued June 12th requiring it to block foreign access to Fable 5 and Mythos 5. The models had launched only three days earlier, on June 9th, with Anthropic claiming Fable 5 surpasses any previously available AI system in capability. The episode marks an escalation of US national security oversight directly targeting named frontier AI models rather than hardware or general policy frameworks.

Anthropic found itself navigating two concurrent government confrontations in mid-June 2026, highlighting the intensifying collision between frontier AI development and US national security policy.
