Linus Chik
I'm a CS undergrad working on AI safety: how LLM agents behave once deployed, evals and interpretability. Currently: a pre-registered study of tacit collusion between LLM agents in auctions.

It started when I was 13, at a Microsoft Azure workshop that showed me what NLP could do. That took me to a bronze medal at IOAI 2025. I'm now a first-year CS student at NTU's College of Computing and Data Science, and independently working through the ARENA curriculum on mechanistic interpretability.
Outside of school and coding: big fan of Riichi Mahjong, rhythm games like osu!, manga, light novels and visual novels, VTubers (結城さくな、星街すいせい) and hunting for underrated music artists. If you want the long version, it lives on Outside.
I'm open to research ideas, hackathon pitches and CTF teams. Message me on LinkedIn or X, or email linusc9516 [at] gmail [dot] com.
