US export controls force Anthropic to disable Fable 5 and Mythos 5 for foreign nationals

美政府出口管制致Anthropic禁用Fable 5与Mythos 5

The US government suspended foreign-national access to Fable 5 and Mythos 5 on national security grounds. Anthropic disabled both models immediately; other Claude models are unaffected. Anthropic calls it a misunderstanding and is working to restore access. DAIR.AI's Elvis Saravia said he dropped Claude entirely this week and stressed the importance of sovereign AI. The post doesn't disclose the specific export control clause or a timeline for restoration.

Why it matters: Anthropic forced to disable two undisclosed models under export controls, affecting its own foreign staff — dense information, direct conflict. Score held at 82 because it's a single-source tweet; Anthropic's official statement and the specific regulatory text aren't out yet.
