Meta AI

Meta's open-source strategy — releasing the Llama model family to the public — has been the most disruptive move in AI since ChatGPT's launch, democratizing access to frontier model weights and spawning thousands of fine-tuned derivatives. Llama 3 (released April 2024) with its 405B parameter version achieved performance comparable to GPT-4 at open-source pricing (free). Meta AI is now the world's most widely deployed AI assistant, integrated into WhatsApp (3B users), Instagram, Facebook, and Messenger. The company is spending $37B on AI capital expenditures in 2024, and Mark Zuckerberg's bet on open AI infrastructure is profiled in The Wall Street Journal's series on the AI wars.
