About
Hi, I'm Hyeonbin.
Interested in how AIs “learn”.
I'm a master's student @ KAIST AI, advised by Minjoon Seo.
and also an intern on the AI Companion Team @ KRAFTON.
I'm
interested in how agentic systems can self‑improve based on iterative feedbacks.
Previously, I did research on LLM reasoning, including latent and mathematical reasoning.
Feel free to contact me for discussions and collaborations! :)
