Llama 4

Llama is Meta's open model family and surrounding developer ecosystem. Official search results present the site as the home for industry-leading, open-source AI models such as Llama 4, together with documentation, licenses, prompting guides, and ecosystem resources. The website is aimed less at casual chatting and more at developers, researchers, and enterprises that want to access, deploy, customize, or build on Meta's model stack in their own products and workflows.
