If America just banned all chinese models that would wipe out most of the open weights landscape in AI, especially anything close to the frontier. I could easily see that happening if a Mythos tier model comes out of a Chinese lab in early 2027. It doesn't meaningfully change the research competition between OAI/Anthropic/Google/SpaceX but it does pad all of their pockets by removing cheap competition and it gives the government far greater control over AI usage de facto.
