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 3.1's 405B-parameter version (July 2024) reached performance comparable to GPT-4 with weights anyone could download for free. Meta AI is integrated into WhatsApp, Instagram, Facebook, and Messenger, and the company is spending tens of billions a year on AI capital expenditure.
