Anthropic Disables Fable and Mythos AI Models After US Export Control Directive

Anthropic shut down its newly launched Fable 5 and Mythos 5 models on Friday night, just days after their release, following a US Commerce Department directive that subjected the models to export controls. The company stated that abruptly disabling access for all customers was the only way to ensure immediate compliance with the government order. According to an Axios report, the Trump administration was concerned about a jailbreak that bypassed safety guardrails on topics including cybersecurity and biology, and requested a pause to harden the national security apparatus, a process expected to be completed in a few weeks.
