About
Hi, there! I’m Yifei, currently a member of technical staff at xAI, on leave from my Ph.D. at Berkeley advised by prof. Sergey Levine.
These days, I am most interested in interactive decision-making/reinforcement learning with LLM/VLMs (i.e. LLM/VLM agent). In particular, I am interested in large-scale self-improvement where the agent improves itself through open-ended reinforcement learning without relying on any human supervision.

If time allows, I will try to put down my reflections in blog posts. Feel free to let me know if there is a specific topic that you would like me to write a blog post about!
