Meta’s VP of AI research, Joelle Pineau, is planning to leave the company, she announced in a post on Facebook Tuesday. Pineau said she’s leaving in May after more than two years overseeing FAIR, Meta’s internal AI research lab led by Yann LeCun.

Pineau’s exit comes as Meta ramps up its AI efforts, with the company planning to spend $65 billion on AI infrastructure in 2025.

In a statement to Bloomberg News, a Meta spokesperson said the company does not have an immediate replacement for Pineau but is conducting a search for her successor. Last year, Meta reportedly reorganized the company to have its AI research unit report to the company’s chief product officer, Chris Cox.

As for Pineau, the executive said she’ll take some time off before jumping into an unnamed “new adventure.”
