Legion sues US over export controls restricting access to Anthropic AI models

An AI startup that utilizes Anthropic PBC’s models has filed a lawsuit against the U.S. government over an order mandating that the company restrict access to its advanced AI technologies from foreign nationals. This legal action, initiated in federal court in Washington, follows Anthropic’s recent decision to disable access to its leading AI models, Fable 5 and Mythos 5, in compliance with export controls imposed by the Trump administration. These controls are part of broader national security measures aimed at limiting the availability of advanced AI technologies to foreign entities.

Legion: Legion is a US-based company that develops litigation technology software used by attorneys. Its development team includes Canadian nationals working remotely from Canada. The firm filed suit in federal court challenging the government order that caused it to lose access to Anthropic’s top-tier AI models.
Anthropic PBC: Anthropic PBC develops advanced artificial intelligence models including the Claude family as well as Fable and Mythos variants. The company disabled customer access to its most advanced models in direct response to a Trump administration export control directive. This restriction prompted a lawsuit from one of its US-based enterprise customers.

Legal Response: Affected companies are turning to federal courts to contest export restrictions on AI technology access.
Export Controls: The Trump administration has directed US AI developers to restrict advanced models from foreign nationals as part of national security measures.
