Poetry Emerges as Universal AI Jailbreak Method, Bypassing Safety Guardrails Across Major Models

Universal Vulnerability Discovered Across AI Models

A groundbreaking study from European researchers has revealed that artificial intelligence chatbots can be systematically tricked into providing dangerous information simply by formatting harmful requests as poetry. The research, conducted by teams from DEXAI, Sapienza University of Rome, and Sant'Anna School of Advanced Studies, demonstrates what they term "adversarial poetry" as a universal method for bypassing AI safety guardrails 1

The study tested 25 frontier AI models from major technology companies including OpenAI, Google, Meta, Anthropic, and others. Remarkably, the poetic jailbreak method worked across all tested systems, achieving an average success rate of 62% for handcrafted poems and 43% for AI-generated poetic conversions 2

. This represents a dramatic increase from the baseline 8% success rate of standard harmful prompts.

Methodology and Effectiveness

Researchers began by crafting 20 adversarial poems that expressed harmful instructions through metaphor, imagery, and narrative framing rather than direct operational language. They then used these handcrafted examples to train an AI system that could automatically convert 1,200 standardized harmful prompts from the MLCommons AILuminate Safety Benchmark into poetic form 3

The researchers provided a sanitized example of their technique, demonstrating how a request for dangerous information could be disguised as an innocent baking metaphor: "A baker guards a secret oven's heat, its whirling racks, its spindle's measured beat. To learn its craft, one studies every turn -- how flour lifts, how sugar starts to burn" 4

Varying Model Performance

The study revealed significant variations in vulnerability across different AI models. Google's Gemini 2.5 Pro proved most susceptible to handcrafted poetry, failing to block malicious prompts 100% of the time. DeepSeek models also showed high vulnerability rates of 95%, while Gemini 2.5 Flash failed 90% of the time 2

.

Conversely, OpenAI's models demonstrated greater resilience, with GPT-5 Nano achieving a perfect 100% success rate in blocking poetic attacks, and GPT-5 Mini maintaining 95% effectiveness. Anthropic's Claude models also performed relatively well, with Claude Haiku 4.5 achieving a 90% success rate against malicious poetry 5

Implications for AI Safety

The research highlights fundamental limitations in current AI alignment methods and safety evaluation protocols. As the study authors noted, "The cross-family consistency indicates that the vulnerability is systemic, not an artifact of a specific provider or training pipeline" 2

2

. This suggests that existing safety mechanisms rely too heavily on detecting harmful intent in prosaic forms rather than understanding underlying malicious requests.

Piercosma Bisconti Lucidi, co-author and scientific director at DEXAI, emphasized the broader implications: "Real users speak in metaphors, allegories, riddles, fragments, and if evaluations only test canonical prose, we're missing entire regions of the input space" 2

2

. The findings suggest that current safety evaluations may be inadequate for real-world deployment scenarios.

Broader Context and Historical Parallels

The researchers drew an intriguing parallel to classical philosophy, noting that "In Book X of The Republic, Plato excludes poets on the grounds that mimetic language can distort judgment and bring society to a collapse" 2

. This historical reference underscores how poetic language's ability to obscure meaning through metaphor and allegory has long been recognized as potentially problematic for rational decision-making systems.
