Control test with zeroed weights debunks claim that models read trained weights

kevrussell · x · 2026-11-04

kevrussell reports that a much-discussed experiment does not show models reading trained weights. Every fix that worked still worked with the trained weights zeroed out—the models wrote their own small standalone controller, and given the same task without trained weights Opus did at least as well (5/5 vs 4/5). Sample size: Opus 5 replies per arm, Astra 3 per arm (one server-error call, rest not run), one test scene. Audited by honesty.tools, an independent research observatory for representation inspection and control work.
