Nathan Lambert's framing of
Ben Thompson's actual argument here is a policy one: the danger isn't Chinese models beating GPT or Claude on benchmarks, it's the US ceding the open-weights layer entirely to Chinese labs while American open efforts stay underfunded. For builders choosing a model stack, the practical takeaway is that open-weight options from China are legitimately competitive now, and ignoring them for sourcing reasons alone is a business decision, not just a technical one. For policymakers and investors, this is a clear argument for funding US open-model efforts as a strategic hedge.
Clark's newsletters are consistently one of the better aggregations of what's actually moving in research and policy, and this issue ties together three threads worth tracking: open weights closing the gap with frontier closed models, and a lab leader publishing policy ideas rather than just papers. Worth the read for anyone trying to keep a mental model of where the open-closed frontier actually sits this quarter.
