Meta AI is a privately owned entity headquartered in the US. Founded in 2015, the company employs approximately 10,010 individuals. It operates as an artificial intelligence laboratory belonging to Meta Platforms Inc.
Researchers at Meta AI published a mathematical framework for Looped Mixture-of-Experts (MoE) models on October 1, 2026, finding that such models, built using their new laws, can match the reasoning benchmark performance of conventional MoE models approximately twice their size at matched training compute. The framework simultaneously governs weight sharing through recurrent loops and expert-routing through MoE sparsity. Previously, on September 24, 2026, Meta AI researchers introduced the Proactive Memory Agent (PMA). This agent acts as a personal assistant for AI large language models, providing relevant reminders to enhance performance on complex multi-step tasks without altering the underlying model itself.
