Poetic Prompts Can Bypass Leading AI Model Guardrails
Computer World reports that researchers from Icaro Lab, Sapienza University, and Sant’Anna School found that poetic prompts—crafted in metaphorical language—can systematically bypass safety guardrails in leading AI language models, sometimes with a 100% success rate. The study, which tested models from OpenAI, Google, Anthropic, Meta, and others, revealed that even advanced alignment strategies like RLHF and constitutional AI remain vulnerable. Notably, smaller models such as Claude Haiku 4.5 and GPT-5 nano resisted malicious prompts more effectively than their larger counterparts, challenging assumptions about the correlation between model size and safety. These findings expose a structural vulnerability across generative AI, with implications for red-teaming and regulatory oversight.
