白宫说Moonshot AI 18天蒸馏出Kimi K3，技术专家直呼不可能。这事关乎开源模型存亡，初创公司都在反对。
白宫声称Moonshot AI通过蒸馏Anthropic的Fable 5（6月9日发布）在7月16日推出了Kimi K3。实际开发时间仅18天，因为Fable在6月12日至7月1日因出口管制暂停。技术观察者认为在18天内蒸馏一个2.8万亿参数模型在物理上不可行。近200家公司（含Y Combinator、Replit、Proton）警告禁止中国开源模型会扼杀数百家初创企业。

37 days to distil a frontier model?
The White House says Moonshot AI distilled Anthropic’s Fable 5 to build Kimi K3. Fable launched on 9 June. K3 launched on 16 July. That’s 37 days on paper - but in practice it’s 18, because Fable was suspended from 12 June to 1 July over export controls.
18 days to hammer a frontier model millions of times, process the outputs, and train a 2.8 trillion parameter system. Technical observers say that’s not just unlikely - it’s physically implausible.
The administration argues Moonshot ran a sophisticated, covert distillation platform over a longer window, hopping between access methods to avoid detection. But if they were distilling before Fable existed, what exactly were they distilling from?
And who wins if Chinese open-weight models are banned? The closed frontier labs. Start-ups that depend on low-cost open models get funnelled onto pricey closed APIs. Nearly 200 companies - including Y Combinator, Replit, and Proton - warned in writing that this would wipe out hundreds of start-ups overnight.
