周厚全

PhD student at HLT@SUDA, co-advised by Prof. Zhenghua Li and Prof. Min Zhang.

My research focuses on text error correction — spelling correction, grammatical error correction — and the evaluation and application of large language models. Previously I worked on constituency parsing, dependency parsing, and part-of-speech tagging.


Projects

🫑青椒模拟器 — A Little Simulator Powered by LLMs
I am interested in building LLM-powered applications. Here is a little simulator that Spico197 and I made: 🫑青椒模拟器. Feel free to play and give us feedback! Thanks to Kimi for API credits, and Warrier for the connection.
🚀 A Platform for LLM-powered Applications
Building on 🫑青椒模拟器, we developed a dedicated platform for LLM-powered applications with two new simulator demos.
🦗 赛博斗蛐蛐 — Cyber Crickets
How would LLMs fare at Texas Hold'em — a game demanding both mathematical reasoning and psychological tactics? We built an arena where Claude, ChatGPT, Gemini, Qwen, Kimi, and DeepSeek compete with table talk, opponent profiling, and visible chains of thought. Kimi stood out with effective bluffing strategies.
