An artificial intelligence startup that uses Anthropic PBC’s AI models sued the US over a government order that the maker of Claude and Mythos keep its most advanced technology out of the hands of foreign nationals.
The suit, filed Tuesday in federal court in Washington, comes less than two weeks after Anthropic disabled access to its most advanced AI models — Fable 5 and Mythos 5 — in response to the Trump administration’s export control. Legion, a litigation-technology company that builds tools for attorneys, is based in the US but said its software development employees include Canadian nationals who work from Canada.
