U.S. partially reverses Anthropic AI ban for Mythos but keeps Fable 5 off the market

General News

Summary

Anthropic has regained limited U.S. approval to redeploy Claude Mythos 5 to a restricted set of organizations that operate and defend critical infrastructure. The company still cannot make Fable 5 broadly available, so the public rollout remains blocked for now. The change follows direct engagement with the U.S. government and appears to cover more than 100 companies and institutions. The article frames this as a sign that frontier AI releases are increasingly governed by export controls and controlled access rather than open launches.
