Welcome to the AGI era of AI governance
The U.S. government forced Anthropic to suspend foreign access to its Claude Fable/Mythos models, opening a new AI governance era.
“The executive branch of the United States forcing Anthropic to turn off access — both internally and externally — to their latest Claude 5 Mythos/Fable models is the starting gun of a new era in AI governance.”— Nathan Lambert
The U.S. executive branch compelled Anthropic to cut off access to its frontier Fable/Mythos models for foreign nationals and users abroad, reportedly after Amazon tipped off the White House about a narrow jailbreak-related cybersecurity concern. Lambert frames this as the start of a new, unstable AGI-era governance regime, warning that model-weight export bans, political targeting of Anthropic, and economic instability could undermine the U.S. AI industry.
