GPT-5.6 launches in gated release; U.S. government restricts frontier AI model access

OpenAI announced GPT-5.6 in three tiers (Sol, Terra, Luna) but restricted early access to government-vetted partners at the Trump administration's request, framing the move as temporary while expressing frustration with the emerging involuntary licensing regime. Separately, the U.S. Commerce Department partially lifted a two-week export block on Anthropic's Claude Mythos 5, clearing access for 100+ trusted U.S. institutions while maintaining broader export controls. The episode establishes a new regulatory pattern in which Washington exerts direct control over frontier AI model releases, affecting both OpenAI and Anthropic. Additional items in the roundup cover Google integrating computer use into Gemini 3.5 Flash, Meta releasing Brain2Qwerty v2 for non-invasive brain-to-text decoding, and IBM's 0.7nm transistor design.
