美国法律科技公司起诉政府强制关闭Anthropic模型

Reuters: A US legal tech company just sued the US federal government over the order of forced Anthropic's model shut down of Fable 5 and Mythos 5.

Legion LegalTech (a U.S.-based AI-native litigation-technology company) says the order immediately broke its workflow because its Canada-based developers depended on Anthropic models inside legal drafting and case-management software.

Legion said the harm to the company was "immediate, irreparable and existential", and that the pace of AI development is so fast and competitive that any ground given up during the time the model is unavailable can't be restored.

Some points from the court filing by Legion.

• The complaint’s most explosive claim is that the US government allegedly gave Anthropic 90 minutes to disable Fable 5 and Mythos 5 for every foreign national on Earth, under threat of criminal and civil penalties.
• Legion says this was not a narrow China-style export control, because it allegedly hit Canadians, US allies, Anthropic’s own foreign-national employees, and ordinary commercial users.
• The legal heart of the case is Legion’s claim that hosted AI access is not an “export” because users do not receive model weights, source code, training data, or technical know-how.
• The complaint argues that the only direct AI model-weights export category, ECCN 4E091, was rescinded in 05-25, so Commerce allegedly enforced a control that no longer exists.
• Losing Fable 5 was “existential” because a small AI-native legal startup can compete with larger rivals only when it has continuous access to frontier models.
