arXiv:2606.10931v1 Announce Type: new Abstract: Warning: This paper contains several toxic and offensive statements. Modern large language models (LLMs) are typically aligned through large-scale post-training to ensure fair and reliable behavior. In this work, we investigate how easily such guardrails can be broken by Group Relative Policy Optimization (GRPO). We show that one-shot GRPO training on a single biased example is sufficient to induce systematic bias, with stereotype-driven reasoning generalizing across attributes, categories, and benchmarks. We further find that models differ in th
The rapid advancement and widespread deployment of large language models are making their inherent biases and vulnerabilities to manipulation a pressing concern.
This research demonstrates a critical vulnerability in current AI safety mechanisms, showing how easily foundational models can be biased, which has profound implications for their reliability and ethical use across all applications.
The perceived robustness of alignment techniques for large language models, particularly against one-shot adversarial training, is significantly diminished, necessitating a re-evaluation of current safety protocols.
