Interpreting a 4-Billion-Key Election Model Built with Claude Opus
AndyMasley · x · 2026-11-04
AndyMasley had Claude Opus build a 4-billion-key model to predict the US election, arguing the classic 13-key model lacked parameters for national elections' subtleties and that the 4-billion-key version "looks good for the Dems tonight." When attempting interpretability work on the keys, he found each key no longer maps to one clear concept — a hands-on case of the tension between scale and interpretability.
