About
I am an AI Research Engineer at KRAFTON AI, where I work on in-game embodied agents for real-time human-AI collaboration. My research focuses on evaluating and aligning co-playable agents by grounding model behavior in gameplay trajectories, dialogue, and player preference signals. I am particularly interested in building evaluation and data-generation pipelines that make agent behavior more measurable, scalable, and aligned with user experience.

2026.06 · PUBG Ally enters public beta
- PUBG Ally is the world’s first in-game AI agent: a voice-enabled teammate that reasons, acts, and plays alongside you in a live battle royale.
- Runs on-device with NVIDIA ACE; speaks English, Korean, and Chinese.
- I evaluate and align Ally so it behaves like a teammate players actually want. Our team shared the technical story; a full tech report is coming soon.
