In a surprising development, Joelle Pineau, the head of artificial intelligence (AI) research at Meta, has announced her departure from the company. Pineau, who serves as the vice president of AI research, shared the news in a LinkedIn post, stating that her last day at Meta will be on 30 May.
Her exit comes at a pivotal moment for Meta as the company aims to assert its dominance in the competitive AI landscape against rivals like OpenAI and Google. CEO Mark Zuckerberg has made AI a central focus, investing billions in the ambition to create an AI assistant with over a billion users and achieving artificial general intelligence—machines that can perform tasks and make decisions akin to human capabilities.
“In light of the significant changes happening in the world and the accelerating race for AI, I believe it’s time to make room for others to continue this important work,” Pineau remarked. “I’ll be cheering for you all, confident that you have everything needed to develop the best AI systems and responsibly integrate them into the lives of billions.”
Pineau has been a key figure in Meta’s AI endeavors, leading the company’s fundamental AI research unit, known as FAIR, since 2023. Her leadership has been instrumental in advancing various cutting-edge projects, including Meta’s open-source Llama AI models and the widely-used PyTorch software for developers.
Having joined Meta in 2017 to establish its Montreal AI research lab, Pineau is also a computer science professor at McGill University, where she co-directs the reasoning and learning lab.
Her announcement comes just weeks before Meta’s upcoming LlamaCon AI conference on 29 April, where the company is expected to unveil the latest version of its Llama models. Chris Cox, Meta’s Chief Product Officer, indicated in March that Llama 4 will support AI agents, a trending topic in the generative AI space. Additionally, reports suggest that a standalone app for Meta’s AI chatbot may also be announced.
A spokesperson from Meta expressed gratitude for Pineau’s contributions, stating, “We thank Joelle for her leadership of FAIR. She has been a vital advocate for open source and has driven significant breakthroughs in our products and the underlying science.”
While Pineau has not disclosed her future plans, she indicated that she will take some time for reflection before embarking on her next adventure.
“Meta AI” Standalone App
As CNBC reported a month ago, Meta is set to introduce a standalone app for its AI assistant “Meta AI” in the second quarter of 2025. This move aligns with Zuckerberg’s ambition to position Meta as a leader in AI, competing with companies like OpenAI and Alphabet.
The Meta AI chatbot, which debuted in September 2023, serves as a generative AI assistant integrated into Meta’s apps, including Facebook and WhatsApp. Recently, the chatbot replaced the search feature in these platforms, allowing users to interact with it more directly.
Zuckerberg has stated that he aims for Meta AI to reach over a billion users this year, transforming it into the leading AI assistant. While currently available only through Meta’s apps and website, a dedicated app could enhance user interaction and personalization.
Additionally, Meta is exploring a subscription model for its AI services, similar to offerings from competitors like OpenAI and Microsoft. Amid growing pressure to innovate, Zuckerberg has emphasized the importance of advancing Meta’s AI technologies. The company has not yet commented on the details of the app or its features.
