The Trump administration forced Anthropic to shutter Mythos 5

anthropic's frontier models, mythos 5 and fable 5, remain offline after 14 days of intense negotiations with the white house, which demanded a ban on access for foreign nationals due to national security concerns. the company claims compliance is currently impossible because existing export control frameworks for dual-use technology cannot be easily applied to live ai systems. although the commerce department previously tested fable 5 without objection, a last-minute report of a guardrail bypass—flagged reportedly by amazon ceo andy jassy—triggered the emergency order. experts like katie moussouris argue the vulnerability is overblown, but the indefinite shutdown could devastate anthropic's business and signal a chaotic future for ai regulation.
