OpenAI researcher dismisses interpolation-regime theory as answer to data wall

willdepue · x · 2026-11-06

A user asks: if we're hitting the data wall, why not keep scaling model size and hope to enter double descent's interpolation regime where test error falls again?

OpenAI's willdepue flatly rejects the premise: "this type of theory is just not real. the interpolation regime?" The attached chart shows the classic double descent curve, with test error peaking at the interpolation threshold (1 parameter/data ratio) before declining with further scale.
