Joelle Pineau, the vice president for AI research at Meta, has announced her decision to step down at the end of May, marking the end of an eight-year tenure at the social media giant.
Pineau, a prominent figure in artificial intelligence research, shared the news in a social media post on Tuesday, stating that the ongoing transformation in the AI landscape and Meta’s evolving focus made this the right time for her departure.
“Today, as the world undergoes significant change, as the race for AI accelerates, and as Meta prepares for its next chapter, it is time to create space for others to pursue the work,” she wrote.
Meta has yet to announce her replacement, and the company has not issued an official comment on her departure.
A key figure in Meta’s AI development
Pineau, who is also a computer science professor at McGill University in Montreal, has been one of the leading voices behind Meta’s open-source AI strategy. Her work has been instrumental in the development of Llama, Meta’s flagship large language model (LLM), which has gained attention for its open-access approach. Unlike some competitors, Meta has chosen to release core components of its AI models to the public, allowing researchers and developers to build upon them.
Her announcement comes just ahead of Meta’s inaugural LlamaCon AI conference on April 29, an event designed to highlight the company’s latest AI advancements. The timing raises speculation about what direction Meta’s AI research will take following her departure.
A decade of AI research at Meta
Meta’s AI research division, previously known as Facebook AI Research (FAIR), has been at the forefront of machine learning, natural language processing, and AI-driven innovation. The group was initially founded in 2013 by a team that included Yann LeCun, one of the world’s most renowned AI researchers.
LeCun stepped down as the director of FAIR in 2018 but has remained Meta’s chief AI scientist, continuing to influence the company’s AI research strategy. Pineau took on a leadership role within the division in 2023, overseeing research efforts during a period of rapid industry advancements and increased competition from companies like OpenAI, Google DeepMind, and Anthropic.
The future of AI at Meta
Pineau’s departure comes at a critical moment for Meta, as the company is making significant investments in AI-driven products, including AI chatbots, virtual assistants, and content recommendation algorithms across its platforms.
With rivals such as OpenAI’s ChatGPT, Google’s Gemini, and Anthropic’s Claude pushing AI innovation forward, Meta faces growing pressure to keep pace in the AI arms race. CEO Mark Zuckerberg has repeatedly emphasised the company’s commitment to advancing AI technology, integrating it further into Facebook, Instagram, and WhatsApp.

Pineau’s open-source philosophy has been a defining feature of Meta’s AI research, setting it apart from competitors who take a more closed, proprietary approach. It remains to be seen whether her successor will continue this ethos or shift towards a more commercially driven AI strategy.
A legacy in AI research
During her tenure, Pineau played a crucial role in fostering ethical AI development, promoting transparency, and ensuring that AI models could be accessed and improved upon by the wider research community.
Her departure raises questions about the next phase of Meta’s AI ambitions and whether the company will continue down the open-source path she championed.
With no immediate successor announced, Meta will need to carefully navigate this transition as it prepares for its next wave of AI advancements in an increasingly competitive field.
