US Commerce Department orders Anthropic to cut Fable 5, Mythos 5 access for foreign nationals

The U.S. Commerce Department on June 12, 2026 issued an export-control directive ordering Anthropic to withhold access to its newest models, "Fable 5" and "Mythos 5," from foreign nationals—including its own employees—prompting Anthropic to temporarily disable both models for all customers worldwide. The company says the directive arrived at 5:21 p.m. ET on June 12, and that it shut the models off immediately to ensure compliance. Access to other models, such as the Claude Opus series, was unaffected. (Anthropic statement)
