Anthropic suspends Fable 5 & Mythos 5 after US order
What happened
Anthropic suspended access to its Fable 5 and Mythos 5 models after a US export-control directive, disabling those models for all foreign nationals. The order applied globally and Anthropic cited a demonstrated jailbreak technique and government national-security concerns, making access loss operationally real for buyers using those models. Watch for supplier notices and regulatory guidance that may expand or clarify affected capabilities
Why the category manager should care
Treat model access as a governance and supply-risk item; map dependencies and require contractual remedies because regulatory orders can cut access overnight
