Meta CEO Mark Zuckerberg on Friday said Shengjia Zhao, the co-creator of OpenAI’s ChatGPT, will serve as the chief scientist of Meta Superintelligence Labs.

Zuckerberg has been on a multibillion-dollar artificial intelligence hiring blitz in recent weeks, highlighted by a $14 billion investment in Scale AI. In June, Zuckerberg announced a new organization called Meta Superintelligence Labs that’s made up of top AI researchers and engineers. 

Zhao’s name was listed among other new hires in the June memo, but Zuckerberg said Friday that Zhao co-founded the lab and “has been our lead scientist from day one.” Zhao will work directly with Zuckerberg and Alexandr Wang, the former CEO of Scale AI who is acting as Meta’s chief AI officer.

“Shengjia has already pioneered several breakthroughs including a new scaling paradigm and distinguished himself as a leader in the field,” Zuckerberg wrote in a social media post. “I’m looking forward to working closely with him to advance his scientific vision.”

In addition to co-creating ChatGPT, Zhao helped build OpenAI’s GPT-4, mini models, 4.1 and o3, and he previously led synthetic data at OpenAI, according to Zuckerberg’s June memo.

Meta Superintelligence Labs will be where employees work on foundation models such as the open-source Llama family of AI models, products and Fundamental Artificial Intelligence Research projects.

The social media company will invest “hundreds of billions of dollars” into AI compute infrastructure, Zuckerberg said earlier this month.

“The next few years are going to be very exciting!” Zuckerberg wrote Friday.
