Anthropic Limits AI Models Under US Security Order

AI safety company Anthropic has disabled its most advanced models for users located outside the United States ^[1]. This action follows a direct national security order from the U.S. government ^[2]. The directive aims to prevent foreign entities from using powerful AI tools to identify and exploit software vulnerabilities ^[1].

Specific high-end models, including those identified as Fable and Mythos, are reportedly affected by the new restrictions ^[2]. This intervention highlights growing government oversight of the artificial intelligence sector ^[1]. While Anthropic adjusts to these security mandates, other industry leaders like OpenAI are facing separate regulatory probes into potential user harm as they prepare for public offerings ^[3].
