## Nauti's Take

Anthropic frames this as a controlled restart, but the real story is the shift in power. The company no longer decides alone who gets access to its strongest model; Washington now has a direct role. That may improve safety, but it also creates an opaque gatekeeping layer: who counts as trusted, who is excluded, and by which criteria? For Europe, this is a reminder not to treat US frontier models as permanently reliable infrastructure.
