Anthropic disables Fable 5 and Mythos 5 models after US export control directive

Summary

Anthropic abruptly shut down access to its newly launched Mythos 5 and Fable 5 AI models after receiving a US Commerce Department directive on Friday evening. The directive subjected the models to export controls restricting their use outside the United States. Anthropic stated that the only way to ensure immediate compliance was to disable both models for all customers. The Commerce Department reportedly had concerns that a "jailbreak" of the Fable 5 model could pose a national security threat.
