The compute race turned into an open confrontation this week. On July 22 the White House science adviser accused Moonshot AI of distilling Anthropic's Fable model to build Kimi K3 and of obtaining export-restricted Nvidia servers, publishing no evidence; Treasury put sanctions and Entity List designations "on the table." A day later the UK and U.S. safety institutes jointly measured K3 and found it "significantly below the most recent frontier cyber-capable models" — the first bilateral state evaluation of a Chinese model, and an answer at odds with the week's rhetoric. Beijing's Commerce Ministry rejected the accusations on July 27 as "a classic case of hegemonic behavior in the AI sphere" and promised countermeasures. Meanwhile the control machinery kept moving in the background: Senator Warren invoked the Export Control Reform Act to compel BIS documents on a foundry loophole she says the 2025 rescission left open, and the record now shows Washington using export-control authority against a specific frontier model — reaching foreign nationals inside the United States.

AI capability has become an instrument of national power, and governments increasingly treat frontier models, the chips that train them, and the talent that builds them as strategic assets — with export controls, restrictions, and state investment to match. This page tracks the competition on observable actions: what governments actually do, what capabilities each bloc demonstrably fields, and how the claims of an 'arms race' hold up against the record.
