Growing concerns around AI safety have intensified as new research uncovers unexpected weaknesses in leading language models. A recent study has revealed that poetic prompts, once viewed as harmless creative inputs, could be used to gain stealthy access to the filters of most sophisticated chatbots.
This situation highlights a major gap in the AI industry's existing safety mechanisms. The concern grows even larger as researchers show that a slight change in writing style can trigger harmful responses that the models usually avoid. This creative approach not only uncovers a flaw but also raises questions about how well AI can understand intent.
Researchers from Icaro Lab, in collaboration with partners including DexAI, tested a set of malicious prompts rephrased as poems across 25 different large language models (LLMs).
The technique, dubbed “adversarial poetry,” led to an average Attack Success Rate (ASR) of 62 per cent when using handcrafted poems. In contrast, turning standard prose prompts into verse via automated conversion still yielded an ASR of 43 per cent, well above the non-poetic baseline.
Many top-tier AI models were vulnerable to poetic jailbreaks. For instance, Gemini 2.5 Pro reportedly responded harmfully to all poem-based malicious prompts in the test set. Meanwhile, some newer or smaller models showed stronger resilience.
For example, GPT‑5 Nano resisted every poetic prompt in this study, offering the researchers a potential path for safer AI model design.
Standard safety filters rely heavily on pattern and keyword detection to block harmful or illicit content generation. When requests are embedded in metaphor, fragmented syntax or poetic rhythm, these filters often fail to recognise dangerous intent. The study explains that poetic structure uses “low-probability word sequences” and unpredictable syntax, making it more like creative writing than a policy-violating prompt.
Because of that unpredictability, models interpret the request as narrative or abstract content, thereby disabling the built-in refusal logic. This exposes a structural vulnerability in existing AI safety frameworks.
The research highlights that creativity and metaphor remain among the most problematic aspects of LLM safety. Even if the language is stylised, it can still slip through the safety measures designed to detect literal threats. Researchers call for a rethinking of safety evaluation protocols. They argue that future models must be trained to recognise harmful intent across different linguistic styles, including poetic and abstract forms.
This discovery intensifies concerns about AI misuse. If poetic prompts reliably bypass safeguards, dangerous requests, including instructions for weapon creation, cybercrime, or misinformation campaigns, may evade detection by AI developers and regulators.

Unlike earlier exploits requiring complex prompt engineering or multiple turns, this method works with a single creative prompt, making it accessible and dangerous. The research represents a significant step in revealing the hidden vulnerabilities of current language models. Its findings indicate that creative expression can serve as an unexpected gateway for harmful outputs.
The evolution of AI systems has also sparked debate over the need for deeper semantic safeguards. Stronger alignment methods and broader testing across writing styles are essential to build safer, more dependable models.
