Yoav Goldberg: Editing model weights is mechanical once we can read them
yoavgo · x · 2026-11-03
Responding to a question about whether editing weights is more than changing numbers, AI researcher Yoav Goldberg argues the difficulty lies in reading, not writing. Weights aren't "just an array of floats" — they're structured into matrices and vectors with known computations, and once humans can truly interpret them, editing becomes mechanical enough to be a course assignment (he notes such questions have already been used in exams).
