US Lifts Restriction on Anthropic’s Claude Fable, Mythos 5
Anthropic announced that it has received notice that the U.S. Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.
The company said Mythos 5 has already been restored for select U.S. organisations after receiving government approval on June 26.
Anthropic added that it will continue to expand access through its Glasswing cybersecurity program, which provides vetted organisations with access to advanced AI models for defensive security testing.
In a post on X, Commerce Secretary Howard Lutnick said officials worked closely with Anthropic to review the models before approving broader access.
“Over the past two weeks, we have worked closely with Anthropic to analyse and approve Fable 5 to ensure alignment across the US Government and strengthen America’s leadership in AI,” Lutnick wrote.
The restrictions were imposed in mid-June under what Anthropic described as a government directive issued under national security authorities.
Meanwhile, Anthropic on Tuesday introduced Claude Science, an artificial intelligence app for researchers that integrates common scientific tools, produces auditable artifacts, and manages computing resources.
The platform includes a coordinating agent with more than 60 skills and connectors for genomics, proteomics, and cheminformatics, plus a reviewer agent that checks citations and calculations, the company said.
Claude Science is available in beta on macOS and Linux for Pro, Max, Team, and Enterprise plans, according to a statement. Wall Street Up as Tech Stocks Dominate Global Markets Theme
