Meta AI
In plain wordsThe artificial intelligence research group of Meta, the company behind Facebook and Instagram, known for the PyTorch software and the Llama models. It is also the name of Meta's chatbot.
The AI organization of Meta Platforms, built around its Fundamental AI Research lab (FAIR), and by extension the company's AI assistant of the same name. FAIR became known for open research and software: it created PyTorchPyTorch, prop. n.: The most widely used free software toolkit for building and training neural networks, especially in research; programmers write ordinary Python and it handles the calculus and the graphics chips. (first released in 2017), now the dominant deep-learning framework, the fastText library, influential self-supervised learningself-supervised learning, n.: A way for AI to learn from huge amounts of unlabeled data by setting itself fill-in-the-blank puzzles, such as guessing a hidden word or a missing patch of an image. methods for vision such as DINODINO, prop. n.: A family of Meta vision models that learn to understand images from millions of unlabeled photos, by training one network to agree with a slowly updated copy of itself., and the Segment Anything ModelSegment Anything Model, prop. n.: A family of AI models from Meta that trace the exact outline of whatever you point to in a photo or video, whether by clicking on it, drawing a box around it or, in newer versions, naming it. (2023). Meta's LlamaLlama, prop. n.: A family of AI language models from Meta, first released in 2023, whose trained settings can be downloaded and run by anyone, making them the foundation for thousands of other AI projects. models, first released in February 2023 with downloadable weights, made it the leading Western advocate of open-weightopen-weight model, n.: An AI model whose trained internal numbers are published for anyone to download and run on their own computers, even if the data and code used to make it stay private. release, although its Galactica science model was withdrawn three days after its 2022 debut and the April 2025 Llama 4 release drew criticism, including over a customized version submitted to the LMArenaLMArena, prop. n.: A public website that ranks AI chatbots by blind taste test: visitors put one question to two unnamed models, pick the reply they prefer, and millions of such votes produce the rankings. leaderboard. The Meta AI assistant, launched in 2023, is built into Facebook, Instagram, WhatsApp and Meta's smart glasses. Since mid-2025 these teams have sat within Meta Superintelligence LabsMeta Superintelligence Labs, prop. n.: A division Meta created in 2025 to pursue superintelligence, gathering all of the company's AI teams under new leaders recruited in an expensive hiring campaign..
Origin
Founded in December 2013 as Facebook AI Research (FAIR), with Yann LeCunYann LeCun, prop. n.: A French-American computer scientist who pioneered the neural networks that recognize images, led Meta's AI research for over a decade, and argues that chatbots alone will not reach human-level AI. as its first director and labs in New York and Menlo Park, later Paris (2015) and Montreal. After Facebook renamed itself Meta in 2021, the organization became Meta AI and FAIR was renamed Fundamental AI Research. LeCun, long its chief AI scientist, left in late 2025 to found a startup.
Usage note
'Meta AI' names both the research organization and the consumer assistant; 'FAIR' refers specifically to the fundamental-research lab.
