US Commerce Dept Halts Foreign Access to Anthropic's Fable 5 and Mythos 5

The US Commerce Department issued an export control directive to Anthropic on June 12, 2026, ordering an immediate halt to foreign access to Fable 5 and Mythos 5, prompting Anthropic to temporarily disable both models across all platforms. The directive targets "any foreign national" regardless of location—including foreign nationals residing in the US and Anthropic's foreign employees—and is grounded in national security concerns. The scope spans multiple channels including AWS Bedrock, Google Cloud, Microsoft Foundry, Snowflake, Box and the direct Claude API, with the full shutdown carried out within hours of the directive's receipt. Other Claude models are unaffected.
