DARWIN: Evolving Jailbreak Adversary and Guardrail for LLM Safety Evaluation and Protection

Weiwei Qi, Zefeng Wu, Zhilin Guo +5

Most existing LLM safety evaluation and defense methods follow a static formulation: jailbreak vulnerabilities are evaluated with fixed attack methods, and guardrails are trained o…
