Anthropic disabled Mythos 5 and Fable 5 after a US Commerce Department export-control order barred their use abroad. The administration asked for a pause amid reports of a narrow jailbreak letting Fable 5 analyze code for vulnerabilities. Anthropic says the issue produced only minor findings and that other models, like GPT-5.5, have similar capabilities.

The US government issued an export control order to cut off all foreign-national access to Anthropic’s Fable 5 and Mythos 5, citing a potential jailbreak vulnerability. Anthropic says the reported exploit is narrow, already known across other models, and disagrees that it warrants a full suspension. The company plans to share more details within 24 hours and restore access if possible.
