US Grants Anthropic Restricted Access to Mythos 5 for 100 Critical Infrastructure Organizations

The US government has allowed Anthropic to restore access to its advanced AI model, Mythos 5, for approximately 100 vetted organizations defending critical infrastructure. The public-facing Fable 5 remains offline with no release date, while a two-week export ban persists for all other entities. Critics argue this marks a selective rollout of frontier AI, similar to OpenAI's restricted GPT-5 release.

Anthropic says US restored Mythos 5 access: but here's why the ban the world protested remains

The US government has let Anthropic switch Mythos 5 back on, but only for roughly 100 vetted organizations defending critical infrastructure. The public-facing Fable 5 stays offline with no timeline, and the two-week export ban remains in force for everyone else. Critics, including Sam Altman, warn that Washington is now picking which companies get frontier AI—a precedent OpenAI's own restricted GPT-5.6 rollout mirrors.
