- The White House imposed export restrictions on Anthropic's Mythos, driven in part by fears that a China-linked group had accessed the model, according to a Semafor report.
- Anthropic told Semafor the government never raised China during export-control discussions, and the White House has not confirmed the report.
- Trump adviser David Sacks posted on X about the models' reported ability to be jailbroken — a claim Anthropic has denied — without mentioning China.
- If the Chinese government obtained Mythos 5 or Fable 5, it could attempt to reverse-engineer the model through distillation, training a "student" AI to replicate the advanced system's behavior.
- Anthropic has called Mythos too dangerous and powerful for public consumption, yet a Discord group reportedly had access to the model for two weeks before the breach was discovered and cut off.
Why it matters: Export controls on a frontier model like Mythos show the White House is now treating leading AI systems as national-security assets, and the reported China-linked access — which Anthropic says never came up in talks — combined with the two-week Discord breach reveals how porous the perimeter around these models actually is. Distillation would let an adversary clone capabilities without stealing the weights outright.
