Description
Today’s conversation is with Zhu Banghua, CTO of RadixArk / SGLang.
Zhu Banghua was the top student in his undergraduate class at Tsinghua University. He later studied at Berkeley under Jiantao Jiao and Michael Jordan.
After his PhD, he started his first company, NexusFlow. In the open-source community, he was one of the first to get PPO training working end-to-end. Soon after, the company was acquired by NVIDIA.
Less than six months after the acquisition, he walked away from the earn-out package and started another company with his close friend Sheng Ying, building RadixArk on top of SGLang. They raised a $100 million round of funding.
Congratulations to Banghua. Today, let’s dive deep into the story behind it all.
