Anthropic Blocks Fable 5 and Mythos 5 Globally After Trump Export Control Order
Original: Anthropic got hit by export rules nobody understands
Trump export rules forced Anthropic to cut access to Fable 5 and Mythos 5 for all users, including its own staff.
The Trump administration ordered Anthropic to block all foreign nationals from its AI models, a directive so broad it swept in US-based foreign nationals and Anthropic's own employees. Anthropics newest models, Fable 5 and Mythos 5, were taken offline for every user worldwide while the company fought to restore access.

The immediate practical consequence was the full suspension of Fable 5 and Mythos 5, the company's newest and most capable models, for every user, domestic and international alike.
