Constitutional grafting: character training for open models under $500, skipping $440k of compute
voooooogel · x · 2026-10-29
Developer wassname open-sourced constitutionalgrafting, claiming success at baking a new moral character into an open-weight model for under $500. The method trains LoRA adapters on the Base model using a virtue-ethics constitution, then grafts them onto the Instruct model — bypassing roughly $440k of training at under $1k. The demo character is Musonius; the repo includes configs, constitution texts, and a research journal (WIP).
