Why it matters

DARWIN’s experiments support continually updating jailbreak evaluations and guardrail training rather than relying on fixed attack strategies and datasets.

DARWIN is a research framework that evolves jailbreak strategies through discovery, mutation, selection, and target feedback, then trains guardrails on emerging adversarial prompts. The authors report attack success above 90% on GPT-5.5 and 95.0% average unsafe recall for DARWIN-Guard across evaluated safety benchmarks, alongside a nearly 100% benign pass rate on standard benign benchmarks.
