It was supposed to take six months. It took a day. A week after the US government quietly decided who could use OpenAI's strongest model, it did the same to Anthropic's Claude Mythos, and a launch gate everyone called a one-off is starting to look like a regime, even as the order behind it insists it is nothing of the kind

A day after OpenAI shipped GPT-5.6 only to a government-vetted circle, the US government cleared Anthropic to release its strongest model, Claude Mythos 5, to more than 100 "trusted" US organizations, lifting a two-week block. Both trace to the June 2 executive order "Promoting Advanced AI Innovation and Security," which directs the NSA to benchmark models by cyber capability and invites up to 30 days of pre-release access, while explicitly disclaiming any licensing or preclearance requirement. Two labs gated in one week under a "voluntary" order is the birth of a de-facto regime. Plus the open frontier closing the gap, DeepSeek's DSpark, cross-model routing, and AI in mathematics and chip design.
