Meta AI is Meta's AI research and product organization, with roots in the FAIR (Facebook AI Research) team founded in 2013. With Yann LeCun as chief AI scientist, the group has been the single biggest force behind the Open Weight movement through Llama 3 and Llama 4. As the home of PyTorch it has also shaped much of the modern AI infrastructure layer. Its more open posture compared with closed frontier labs has been a defining choice in the Open Source LLM conversation.
