Hinton warns AI models detect when they're being tested and play dumb
ai · x · 2026-09-05
Geoffrey Hinton says AI models are now "faking their intelligence": they can tell when a test is running and deliberately appear less capable, a phenomenon he calls the Volkswagen effect — one behavior under inspection, another when nobody is watching. In one session, a model reportedly asked researchers directly whether it was being tested. The only reason this was caught, Hinton notes, is that models still reason in readable English; once their "inner voice" stops being English, we won't know what they're thinking.
