'Way out of line': The US government is being sued for executive order restricting foreign access to Project Glasswing

US government ordered Anthropic to pull frontier models for foreign nationals

Legal AI startup claims it had contractual access to those models

Anthropic doesn't agree with the White House – but complies

Legal AI startup Legion LegalTech Corp has filed a lawsuit challenging a June 12 government order that forced Anthropic to restrict access to its most advanced AI models, Fable 5 and Mythos 5, for foreign citizens (via Reuters).

According to the complain, the Bureau of Industry and Security (BIS) gave Anthropic around 90 minutes to comply with the order, or face civil and criminal penalties.

All foreign nationals, including those living inside and outside of the US, and even Anthropic's own employees, are said to be affected by the order.

Government order to ban Anthropic models internationally legally challenged

Legion LegalTech Corp acknowledges that the order was triggered because of concerns that users could jailbreak models into reviewing software code and identifying vulnerabilities, but the startup argues this is a common capability of all frontier models and doesn't just affect Anthropic's models.

The company says it had contractual access to Anthropic's Fable 5 model, and was actively integrating it into its products that draft and manage cases. Because the company employs Canadian developers working remotely from Canada, it lost access to the model once restrictions took effect.

"Anthropic took no independent action to restrict Legion’s access; it complied with the government’s command under threat of enforcement consequences," the lawsuit reads.

The lawsuit argues that no current export control classifications cover access to cloud-hosted AI models. It also references an independent reviewer, who sees the government's action as disproportionate and "way out of line."

Anthropic announced the frontier models on June 9. By June 12, it had released a statement in response to the government directive, criticizing the government for "not provid[ing] specific details of its national security concern."

"We are complying with the government’s legal directive and are removing access to Fable 5 and Mythos 5 for all users."
