US Export Control Halts Foreign Access to Anthropic's Fable 5 and Mythos 5 Models
English summary
The US government issued an export control directive requiring Anthropic to halt access to its Fable 5 and Mythos 5 models for any foreign national, including Anthropic's own foreign employees, worldwide. The order, received at 5:21 PM ET, cited a jailbreak technique; Anthropic reviewed the demo and found only minor, previously known vulnerabilities that also exist in other public models. Anthropic complied but expressed disagreement, arguing that if this standard were applied industry-wide, all frontier model deployments would be stopped. Access to other Anthropic models remains unaffected.
