"Our commitment to FAIR remains strong," a Meta spokesperson told CNBC. "Our strategy and plans will not change as a result of recent developments."
In a statement to CNBC, Pineau said she is enthusiastic about Meta's overall AI work and strategy.
"There continues to be strong support for exploratory research and FAIR as a distinct organization in Meta," Pineau said. "The time was simply right for me personally to re-focus my energy before jumping into a new adventure."
Meta on Thursday named FAIR co-founder Rob Fergus as Pineau's replacement. Fergus will return to the company to serve as a director at Meta and head of FAIR, according to his LinkedIn profile. He was most recently a research director at Google DeepMind.
