Hey~ I'm Wanghan Xu! 👋 Feel free to ask me anything! I'm a PhD student at Shanghai Jiao Tong University, working with Prof. Tao Gui on foundation models. My current focus is advancing agentic coding through Recursive Self-Improvement (RSI). Ask me about Atria Dawn, Benchmark Radar, or my latest work! You can try to guess my WeChat ID (if you want to add me) 📱, but I won't tell you directly hehe~ You can only ask yes/no questions, and I'll answer yes or no! Here's a hint for you 💡: My WeChat ID is made up of pure English letters, 7 characters total. The first 5 characters form a word related to my appearance, and the last 2 characters are letters related to an animal. Good luck! 🍀
