Meta CEO Mark Zuckerberg announced Friday that former OpenAI researcher Shengjia Zhao will lead research efforts at the company’s new AI unit, Meta Superintelligence Labs (MSL). Zhao contributed to several of OpenAI’s largest breakthroughs, including ChatGPT, GPT-4, and the company’s first AI reasoning model, o1.

Zhao, previously a research scientist at OpenAI, played a pivotal role in creating GPT-4 and various lighter models such as version 4.1 and o3. He is among at least eight researchers who have recently transitioned from OpenAI to Meta.

Meta Platforms has appointed Shengjia Zhao, one of the co-creators of ChatGPT and GPT-4, as chief scientist of its recently launched Superintelligence Lab. The announcement was made by CEO Mark Zuckerberg in a Threads post on Friday, as Meta moves to bolster its capabilities in advanced artificial intelligence.
