Big Tech AI Divisions
Meta AI is the AI research and product organization inside Meta (Facebook, Instagram, WhatsApp). The team ships the open-weight Llama model family and operates the FAIR research lab. Meta's open-weight strategy on Llama 2, Llama 3, and Llama 3.1 405B reset the open-weight model landscape and pushed every other major lab to re-state its own release policy.
Why this matters in 2026
Llama 3.1 405B (released July 2024 with open weights) was the largest open-weight model release in history and reshaped the build-vs-buy calculation for enterprise AI teams. PyTorch's continued dominance as the de-facto ML framework means Meta AI hires shape tooling decisions far beyond their employer.
