Anthropic shuts down Mythos access after sweeping U.S. order
Anthropic has suspended access to its advanced AI models, Mythos and Fable 5, following a U.S. government order to restrict foreign national access. The company is complying with the directive while expressing concern over the precedent set by regulating software access for national security reasons.
Why it matters
This marks a significant escalation in U.S. government intervention in the AI industry, signaling a shift toward treating frontier AI models as sensitive national security assets similar to semiconductors.
