Oh! Graph: Fable 5 Blocked 72 Hours After Release—Why the U.S. Shut Its Own Doors

Anthropic's new models, Fable 5 and Mythos 5, drew immediate attention for their overwhelming performance upon release, but were completely blocked just three days later due to national security measures by the U.S. government. In this episode of Oh! Graph, we analyze what happened during those 72 hours from the models' release to their shutdown, why Amazon's report led to White House action, and how this incident is upending the AI strategies of both the U.S. and China through five key graphs.

We also examine the U.S. government's executive order requiring a 30-day pre-review for AI models, the proliferation of Chinese open-source models, and the trend of Chinese models dominating the top spots in weekly usage on OpenRouter. These developments highlight how the AI hegemony race has moved beyond simple performance competition into a battle over access control, export regulations, and technological sovereignty. Furthermore, we explore why this shutdown incident has reaffirmed the necessity of Sovereign AI for third-party regions such as South Korea, Europe, and Canada.
