26-author study: a hardwired frontier AI training pause is technically feasible

wfithian · x · 2026-10-20

A 26-author interdisciplinary working group led by UC Berkeley's William Fithian argues governments could implement a "hardwired pause" of frontier AI training: phase out advanced training chips in favor of specialized inference-only chips that can't practically train new models, enabling a lasting, verifiable international agreement. A WSJ poll of 1,500 registered voters shows 63% support pausing AI development. Authors span Oxford China Policy Lab, Princeton, Stanford and more; co-authorship doesn't imply agreement with every claim.
