James Liu

I'm an incoming Member of Technical Staff at Anthropic.

I'm finishing up my undergrad at MIT, where I was fortunate to work with Han Guo, Yoon Kim, and Song Han. I spent some time at Together AI as a research intern, where I was fortunate to work with Tianle Cai, Tri Dao, and Ben Athiwaratkun along with several other talented people.
