Opus Keeps Butchering a Joke-Rewriting Task, Ignoring Explicit Instructions to Preserve Punchlines

ivan_bezdomny · x · 2026-11-10

A blogger reports that Opus consistently fails on a humor-rewriting problem: it not only fails to write better jokes but actively butchers the original, losing both the premise and the punchline even when explicitly instructed to keep them — and it can't write a working prompt or process for itself.

The author's take: once a smarter model finally solves this kind of problem, the task likely can't be "farmed back down" to less intelligent models — suggesting humor may serve as a marker capability for model intelligence tiers.
