The Korean Telecom Giant at the Center of Anthropic’s Mythos Controversy

Key Points:

• The Trump administration imposed export controls on Anthropic’s advanced AI models, Claude Mythos and Fable 5, following concerns over SK Telecom’s access due to alleged ties to China and identified vulnerabilities flagged by Amazon.
• Anthropic restricted access to these models entirely for foreign nationals after the White House demanded limiting access to US citizens only, a move the company found difficult to implement while preserving privacy.
• SK Telecom, a major South Korean telecom firm with historical business links to China through its parent company SK Group, had been granted access as part of Anthropic’s Project Glasswing, which includes collaborations with US government and other Korean organizations.
• Despite SK Telecom’s denial of current ties to China, US officials remained wary due to the conglomerate’s extensive business interests in China and past joint ventures with Chinese state-owned carriers.
• The dispute remains unresolved after negotiations, with the White House and Anthropic at odds over restoring access, highlighting ongoing national security concerns regarding advanced AI technology export controls.
