We announced ten weeks ago a billion downloads after the release of Llama 4. In just ten weeks, that number is now 1.2. And if you look at Hugging Face (where the downloads are happening), what’s cool is that most of these are derivatives. We have thousands of developers contributing. - Meta Platforms Chief Product Officer Chris Cox, 5/25
