Toby Ord: we can't map benchmark scaling gains to real-world returns, like pre-scaling-law era

tobyordoxford · x · 2026-10-21

Toby Ord points out a methodological gap in RSI debates: pre-training scaling once looked grim (error falling as compute^1/20 per Kaplan/Chinchilla) yet the error-to-revenue transformation was steep (error^-20). When arguing whether r>1 from benchmark scaling results, we have little ability to pin down the benchmark-to-real-world return function, so results can't be carried across to real-world scaling questions.
