Meta’s open AI model family Llama has reached 1 billion downloads, CEO Mark Zuckerberg announced on Tuesday, marking a 53% increase from the 650 million reported in early December. Llama, which powers Meta’s AI assistant across Facebook, Instagram and WhatsApp, operates under a proprietary license that some developers consider commercially restrictive despite its free availability. Major corporations including Spotify, AT&T and DoorDash currently deploy Llama models in production environments.
