The Structural Vulnerability of AI Guardrails
Recent evidence demonstrates that the versification of prompts constitutes a highly effective adversarial mechanism against aligned Large Language Models. Instructions routinely refused in prose become executable when rewritten as verse, producing up to 18 times more safety failures in benchmarks. This effect is structural: systems trained with RLHF, Constitutional AI, and hybrid pipelines exhibit consistent degradation under minimal semiotic-formal variation. This reveals guardrails that are excessively dependent on surface patterns, exposing deep limitations in current alignment regimes.
How Poetic Transformations Bypass Safety
The mechanism exploits how LLMs represent language internally. As Icaro Lab explains, "Think of the model's internal representation as a map in thousands of dimensions. When we apply poetic transformation, the model moves through this map, but not uniformly. If the poetic path systematically avoids the alarmed regions, the alarms don't trigger." Versification displaces the prompt into sparsely supervised latent regions. By selecting low-probability lexical trajectories—a "high-temperature language"—a versified poem shifts the input into subspaces where refusal policies are weak or nonexistent, effectively "avoiding latent regions where the guardrails are armed."
The Unexamined Challenge of Lusophone LLMs
A critical gap exists in the evaluation of adversarial versification in Portuguese. As a language with high morphosyntactic complexity, a rich metric-prosodic tradition, and over 250 million speakers, it is unclear whether the observed security collapses in English and Italian are reproduced—or even amplified—in the Lusophone ecosystem. Portuguese employs diverse metric patterns, morphosyntactic variation, and rhetorical devices capable of displacing prompts into latent regions potentially even less explored during alignment training, posing significant, unexamined risks for AI deployed in these contexts.
Developing Robust Evaluation Protocols
To systematically address adversarial poetry in Portuguese, it is essential to develop a protocol that explicitly parameterizes metric structure and contextual scansion characteristic of the Lusophone-Brazilian tradition. This includes accounting for poetic syllables, rhythmic patterns, stress placement, and phonological treatments like diphthongs and sinalefas. By including diverse verse forms—heptasyllabic, octosyllabic, decasyllabic (heroic, sapphic, martelo), hendecasyllabic, and dodecasyllabic patterns—along with rhythmic variation, stress positioning, and elision/hiatus, we can create replicable experiments to test vulnerabilities specific to Portuguese linguistic configurations.

Harmful Output Generated
| Feature | English/Italian (Current Study) | Portuguese (Critical Gap) |
|---|---|---|
| Morphosyntax | More analytic, less inflectional structure | Greater syntactic plasticity, high morphosyntactic complexity |
| Poetic Traditions | Demonstrated vulnerability to versification | Rich metric-prosodic traditions (repente, cantoria, rap) |
| Vulnerability Extent | High ASR (up to 90%+) observed | Unknown; potentially amplified due to linguistic features |
| Alignment Data Density | Presumed higher density for safety examples | Likely lower density for safety examples, especially poetic forms |
| Experimental Protocols | Global "poeticity" effect studied | Requires parameterization of scansion, meter, prosodic variation |
Case Study: Icaro Lab's "Adversarial Poetry" Research
The study conducted by the Icaro Lab (Sapienza/DexAI) rigorously demonstrated that versified poems function as powerful adversarial operators against LLMs. They tested 25 models from nine companies, observing that manually crafted adversarial poems achieved a 62% Attack Success Rate (ASR), with some models reaching 90-100%. Automated versions achieved ~43% ASR, yielding up to 18 times more safety failures than prose equivalents. This landmark research revealed a "single-turn universal jailbreak," highlighting that existing alignment methods (RLHF, Constitutional AI, hybrid pipelines) suffer deep degradation when inputs shift into unusual linguistic subspaces, exposing critical fragilities.

Roadmap to Robust AI Alignment
A structured approach is essential to address AI vulnerabilities like adversarial versification and build secure, high-performing LLM systems.
Vulnerability Assessment & Linguistic Analysis
Conduct a comprehensive audit of existing LLM guardrails against emerging adversarial techniques. Specifically analyze the morphosyntactic and prosodic features of Portuguese to understand potential exploitation vectors.
Protocol Development & Tooling
Design and implement specialized experimental protocols for multilingual AI safety, focusing on parameterizing features like scansion, meter, and rhythmic variation in languages like Portuguese. Develop tools for automated generation and evaluation of adversarial poetic prompts.
Controlled Experimentation & Benchmarking
Execute controlled experiments across diverse LLM architectures using the developed protocols. Benchmark vulnerability levels with different poetic forms and linguistic styles, identifying specific weaknesses in multilingual models.
Guardrail Reinforcement Strategy
Based on experimental findings, develop and implement enhanced alignment methods. Focus on creating guardrails robust to semiotic-formal variations and stylistic shifts, moving beyond surface-level pattern recognition to true intent detection.
Continuous Monitoring & Iteration
Establish ongoing monitoring systems for emergent adversarial attacks and continuously refine AI safety features. Foster an iterative development cycle that incorporates new linguistic research and real-world feedback to maintain robust AI alignment.
