3rd-year CS undergraduate at Soongsil University. I work at the intersection of AI systems, security, and infrastructure β building things that ship to real users and contributing to open-source projects I rely on.
LLM Jailbreak Comparative Study β Independent research under Prof. Bong Jun Choi (AI Security Lab, SSU)
Evaluated adversarial robustness of Claude Sonnet vs GPT-4o across 4 experiment types and 9 prompt categories. Discovered a turn-count reversal effect in extended multi-turn attacks (Claude 0%β50%, GPT-4o 0%β0% refusal).
