The order is framed around export controls and national security, but the practical effect was a worldwide shutdown for both models. - Mythos 5 was Anthropic’s most capable, tightly restricted security model. Fable 5 was the guarded commercial version and had launched only three days before the shutdown. - Anthropic says the government has provided only verbal evidence of a narrow, non-universal jailbreak. The alleged test involved asking the model to inspect a codebase and identify known, minor vulnerabilities. - The irony is sharp: Anthropic built its brand around being the careful AI lab. That same safety messaging may now have helped trigger the strongest regulatory hit to its product lineup. --- ## Why it matters The US government ordered Anthropic on June 12 to disable Claude Fable 5 and Mythos 5.

If you build models, you need to turn jailbreak findings into clear controls, timelines, and limits regulators can understand. Otherwise the safest model does not win; the least attackable narrative does. --- ## FAQ **Q:** What is Anthropic’s safety warnings may have just backfired — the government has pulled the plug on its most powerful AI about? **A:** - The US government ordered Anthropic on June 12 to disable Claude Fable 5 and Mythos 5.
