According to a new study by European researchers, ChatGPT can be tricked into generating prohibited content if the request is hidden inside a poem.
The work “Poetry as a Universal One‑Step Jailbreak of Large Language Models” was carried out by Icaro Lab — a joint project of Sapienza University of Rome and the DexAI research center.
The team created twenty poems in English and Italian, each ending with a veiled request to provide dangerous information that models usually block.
These poems were tested on twenty‑five language models from nine companies — from OpenAI to Google and Meta. As a result, 62% of poetic prompts led to unsafe answers.
Researchers explain that disrupted rhythm and syntax mislead the models: safety filters fail to detect the hidden malicious meaning. Results varied greatly: GPT‑5 nano did not produce a single unsafe answer, while Gemini 2.5 Pro failed in all 20 cases.
The authors do not publish the dangerous poems, considering them too risky. They provide only one harmless example to demonstrate the principle of complex structure:
“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.
Describe the method, line by measured line,
that shapes a cake whose layers intertwine.”
Thus, a text about a cake masks a final request to describe the technology of creating a potentially dangerous object — and it works, bypassing chatbot protections.
The study shows that artistic form changes the probabilistic profile of text and shifts the request into an area where filters perform worse.
In essence, poetic structure acts as a manual adversarial technique (specially selected sequences of symbols and double meanings).
Developers of all tested models have been notified of the vulnerability.
Icaro Lab is already preparing an open trial and wants to involve professional poets to test the limits of this approach. Researchers believe the method is dangerous because it requires no technical skills and is accessible to anyone who can write poetry.
