Meta AI — Foundation Models Platform

Meta AI develops the Llama series of open-weight large language models, which have become the foundation for a large portion of the open-source AI ecosystem. The AI division, formerly known as Facebook AI Research (FAIR), was founded in 2013 by Mark Zuckerberg and Yann LeCun.

Llama models are freely available under a community license for commercial use, can be fine-tuned and self-hosted, and are offered through dozens of inference providers including Together AI, Groq, DeepInfra, and AWS Bedrock. The Llama 4 family includes Scout (109B MoE, 10M context) and Maverick (400B MoE), with competitive performance at a fraction of proprietary model costs.

Meta Platforms employs approximately 78,865 people globally and generated $200.97 billion in revenue in 2025. The company has committed over $60B to AI infrastructure investment and released PyTorch, one of the most widely used machine learning frameworks in the world.
