Opus 5.5 told to act like GPT-2 copies and extends the user's entire prompt

A user asked Claude Opus 5.5 to act like GPT-2 in a conversation — and the model actually delivered, copying and extending the user's entire prompt just like early language models famously did.
The spot-on imitation of GPT-2's prompt-echoing behavior went viral, with one replier joking "there's a little GPT-2 in all of us." It's a funny showcase of how well newer models can channel the quirks of their predecessors on demand.
